What are the specifications and features of the Miller Spectrum 375 X-TREME?

The Spectrum 375 X-TREME is a portable air plasma cutting system with rated output of 30 amps DC at 92 volts with 240 VAC input power. It features a 400 volts DC open circuit voltage, constant current output characteristic, and operates at a 35% duty cycle at 30 amps with 240 VAC input. The unit includes an XT30 torch designed for handheld use, safety interlock devices, and a rated cutting capacity of 3/8 inch at 18 ipm (457 mm/min) for edge start cuts. (Page 11-13)

How do I properly connect the air/gas supply to the Spectrum 375?

Use only clean, dry air with 90 to 120 psi (621 to 827 kPa) pressure. Obtain a hose with 1/4 NPT right-hand thread fitting, wrap the threads with teflon tape or apply pipe sealant, and install the fitting in the gas/air inlet opening. Route the hose to your gas/air supply. Ensure that all connections are properly assigned and tightened, and verify that correct air pressure and airflow are set to prevent torch overheating. (Page 15)

What electrical input power requirements does the Miller Spectrum 375 need?

The Spectrum 375 accepts either 120 VAC or 240 VAC single-phase input power at 50/60 Hz. For 120 VAC input with 20 amps capacity, it requires 25.6 volts AC RMS with 11.4 amps RMS input current. For 240 VAC input, it requires 13.6 volts AC RMS with 8.1 amps RMS input current. A 15 or 20 ampere individual branch circuit protected by time-delay fuses or circuit breaker is required for 120 VAC input. (Page 11, 15)

4

What should I do if the Spectrum 375 overheats during operation?

If the unit overheats, the thermostat opens, output stops, the Temperature trouble light turns on, and the cooling fan runs. You must wait fifteen minutes for the unit to cool or until the temperature light goes off before continuing. To prevent overheating, reduce amperage or duty cycle before starting to cut again. Exceeding the duty cycle can damage the unit and void the warranty. (Page 13)

5

How do I interpret the status and trouble lights on the Spectrum 375?

The Power light indicates input power status. The Pressure, Cup, and Temperature lights indicate system conditions. A steady Power light means input power is okay and the system is normal if Pressure/Cup/Temp lights are off. When the Pressure light is on, it indicates no or low (below 40 psi) input pressure. When the Cup light is on, the torch cup is loose or off. When the Temperature light is on, the power source has overheated and needs to cool down. Flashing lights indicate specific fault conditions that require checking consumables, torch, or input pressure. (Page 27)

6

What are the recommended cutting speeds for the Spectrum 375 at different amperages?

At 30 amperes output on mild steel, cutting speeds range from 104.8 ipm for 12 gauge to 6.4 ipm for 5/8 inch thickness. At 27 amperes, speeds range from 115.0 ipm for 12 gauge to 4.8 ipm for 5/8 inch. At 20 amperes, speeds range from 158.4 ipm for 1/16 inch to 6.4 ipm for 3/8 inch thickness. These recommended speeds are approximately 80% of maximum, and aluminum and stainless steel cutting speeds may be reduced as much as 20%. (Page 20)

Section 1 − Safety Precautions - Read Before Using

pom_2010−03 Protect yourself and others from injury — read and follow these precautions. 1-1. Symbol Usage DANGER! − Indicates a hazardous situation which, if not avoided, will result in death or serious injury. The possible hazards are shown in the adjoining symbols or explained in the text. Indicates a hazardous situation which, if not avoided, could result in death or serious injury. The possible hazards are shown in the adjoining symbols or ex- plained in the text. NOTICE − Indicates statements not related to personal injury.  Indicates special instructions. This group of symbols means Warning! Watch Out! ELECTRIC SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult sym- bols and related instructions below for necessary actions to avoid the hazards. 1-2. Plasma Arc Cutting Hazards The symbols shown below are used throughout this manual to call attention to and identify possible hazards. When you see the symbol, watch out, and follow the related instructions to avoid the hazard. The safety information given below is only a summary of the more complete safety information found in the Safety Standards listed in Section 1-5. Read and follow all Safety Standards. Only qualified persons should install, operate, maintain, and repair this unit. During operation, keep everybody, especially children, away. CUTTING can cause fire or explosion. Hot metal and sparks blow out from the cutting arc. The flying sparks and hot metal, hot workpiece, and hot equipment can cause fires and burns. Check and be sure the area is safe before doing any cutting.  Remove all flammables within 35 ft (10.7 m) of the cutting arc. If this is not possible, tightly cover them with approved covers.  Do not cut where flying sparks can strike flammable material.  Protect yourself and others from flying sparks and hot metal.  Be alert that sparks and hot materials from cutting can easily go through small cracks and openings to adjacent areas.  Watch for fire, and keep a fire extinguisher nearby.  Be aware that cutting on a ceiling, floor, bulkhead, or partition can cause fire on the hidden side.  Do not cut on closed containers such as tanks or drums.  Connect work cable to the work as close to the cutting area as prac- tical to prevent cutting current from traveling long, possibly unknown paths and causing electric shock, sparks, and fire hazards.  Do not use plasma cutter to thaw frozen pipes.  Never cut containers with potentially flammable materials inside − they must be emptied and properly cleaned first.  Do not cut where the atmosphere may contain flammable dust, gas, or liquid vapors (such as gasoline).  Do not cut pressurized cylinders, pipes, or vessels.  Do not cut containers that have held combustibles.  Wear oil-free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.  Do not locate unit on or over combustible surfaces.  Remove any combustibles, such as a butane lighter or matches, from your person before doing any cutting.  After completion of work, inspect area to ensure it is free of sparks, glowing embers, and flames.  Use only correct fuses or circuit breakers. Do not oversize or by- pass them.  Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B for hot work and have a fire watcher and extinguisher nearby. Touching live electrical parts can cause fatal shocks or severe burns. The torch and work circuit are electrically live whenever the output is on. The input power circuit and machine internal circuits are also live when power is on. Plasma arc cutting requires higher voltages than welding to start and maintain the arc (200 to 400 volts dc are common), but may also use torches designed with safety interlock systems which turn off the machine when the shield cup is loosened or if tip touches electrode inside the nozzle. Incorrectly installed or improperly grounded equipment is a hazard. ELECTRIC SHOCK can kill.  Do not touch live electrical parts.  Wear dry, hole-free insulating gloves and body protection.  Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground.  Do not touch torch parts if in contact with the work or ground.  Turn off power before checking, cleaning, or changing torch parts.  Disconnect input power before installing or servicing this equip- ment. Lockout/tagout input power according to OSHA CFR 1910.147 (see Safety Standards).  Properly install and ground this equipment according to its Owner’s Manual and national, state, and local codes.  Check and be sure that input power cord ground wire is properly connected to ground terminal in disconnect box or that cord plug is connected to a properly grounded receptacle outlet − always verify the supply ground.  When making input connections, attach proper grounding conduc- tor first.  Keep cords dry, free of oil and grease, and protected from hot metal and sparks.  Frequently inspect input power cord for damage or bare wiring − re- place cord immediately if damaged − bare wiring can kill.  Turn off all equipment when not in use.  Inspect and replace any worn or damaged torch cable leads.  Do not wrap torch cable around your body.  Ground the workpiece to a good electrical (earth) ground if required by codes.  Use only well-maintained equipment. Repair or replace damaged parts at once.  Wear a safety harness if working above floor level.  Keep all panels and covers securely in place.  Do not bypass or try to defeat the safety interlock systems.  Use only torch(es) specified in Owner’s Manual.  Keep away from torch tip and pilot arc when trigger is pressed.  Clamp work cable with good metal-to-metal contact to workpiece (not piece that will fall away) or worktable as near the cut as practical.  Insulate work clamp when not connected to workpiece to prevent contact with any metal object.

OM-254 193 Page 2 SIGNIFICANT DC VOLTAGE exists in inverter power sources AFTER the re- moval of input power.  Turn Off unit, disconnect input power, check voltage on input ca- pacitors, and be sure it is near zero (0) volts before touching any parts. Check capacitors according to instructions in Mainte- nance Section of Owner’s Manual or Technical Manual before touching any parts. ELECTRIC SHOCK can kill.  On inverter power sources, failed parts can ex- plode or cause other parts to explode when power is applied. Always wear a face shield and long sleeves when servicing inverters. EXPLODING PARTS can injure. Sparks and hot metal blow out from the cutting arc. Chipping and grinding cause flying metal. FLYING SPARKS can injure.  Wear approved face shield or safety goggles with side shields.  Wear proper body protection to protect skin.  Wear flame-resistant ear plugs or ear muffs to prevent sparks from entering ears. Arc rays from the cutting process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. ARC RAYS can burn eyes and skin.  Wear face protection (helmet or shield) with a proper shade of filter lenses to protect your face and eyes from arc rays and sparks when cutting or watching. ANSI Z49.1 (see Safety Standards) suggests a No. 9 shade (with No. 8 as minimum) for all cutting currents less than 300 amperes. Z49.1 adds that lighter filter shades may be used when the arc is hidden by the workpiece. As this is normally the case with low current cutting, the shades suggested in Table 1 are pro- vided for the operator’s convenience.  Wear approved safety glasses with side shields under your helmet or shield.  Use protective screens or barriers to protect others from flash, glare and sparks; warn others not to watch the arc.  Wear protective clothing made from durable, flame-resistant material (leather, heavy cotton, or wool) and foot protection. Table 1. Eye Protection For Plasma Arc Cutting Current Level In Amperes Minimum Shade Number Below 20 20 − 40 40 − 60 60 − 100 #4 #5 #6 #8 Prolonged noise from some cutting applications can damage hearing if levels exceed limits specified by OSHA (see Safety Standards). NOISE can damage hearing.  Use approved ear plugs or ear muffs if noise level is high.  Warn others nearby about noise hazard. FUMES AND GASES can be hazardous. Cutting produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.  Keep your head out of the fumes. Do not breathe the fumes.  If inside, ventilate the area and/or use local forced ventilation at the arc to remove cutting fumes and gases.  If ventilation is poor, wear an approved air-supplied respirator.  Read and understand the Material Safety Data Sheets (MSDSs) and the manufacturer’s instruction for metals to be cut, coatings, and cleaners.  Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Fumes from cutting and oxygen depletion can alter air quality causing injury or death. Be sure the breathing air is safe.  Do not cut in locations near degreasing, cleaning, or spraying oper- ations. The heat and rays of the arc can react with vapors to form highly toxic and irritating gases.  Do not cut on coated metals, such as galvanized, lead, or cadmium plated steel, unless the coating is removed from the cutting area, the area is well ventilated, and while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes when cut.  Do not cut containers with toxic or reactive materials inside or containers that have held toxic or reactive materials − they must be emptied and properly cleaned first. PLASMA ARC can injure. The heat from the plasma arc can cause serious burns. The force of the arc adds greatly to the burn hazard. The intensely hot and powerful arc can quickly cut through gloves and tissue.  Keep away from the torch tip.  Do not grip material near the cutting path.  The pilot arc can cause burns − keep away from torch tip when trig- ger is pressed.  Wear proper flame-retardant clothing covering all exposed body ar- eas.  Point torch away from your body and toward work when pressing the torch trigger − pilot arc comes on immediately.  Turn off power source and disconnect input power before disas- sembling torch or changing torch parts.  Use only torch(es) specified in the Owner’s Manual. Gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylin- ders are normally part of metalworking processes, be sure to treat them carefully. CYLINDERS can explode if damaged.  Protect compressed gas cylinders from excessive heat, mechani- cal shocks, physical damage, slag, open flame, sparks, and arcs.  Install and secure cylinders in an upright position by chaining them to a stationary support or equipment cylinder rack to prevent falling or tipping.  Keep cylinders away from any cutting or other electrical circuits.  Never allow electrical contact between a plasma arc torch and a cylinder.  Never cut on a pressurized cylinder − explosion will result.  Use only correct gas cylinders, regulators, hoses, and fittings de- signed for the specific application; maintain them and associated parts in good condition.  Turn face away from valve outlet when opening cylinder valve.  Keep protective cap in place over valve except when cylinder is in use or connected for use.  Use the right equipment, correct procedures, and sufficient number of persons to lift and move cylinders.  Read and follow instructions on compressed gas cylinders, asso- ciated equipment, and Compressed Gas Association (CGA) publication P-1 listed in Safety Standards.

OM-254 193 Page 3 1-3. Additional Symbols For Installation, Operation, And Maintenance HOT PARTS can burn.  Do not touch hot parts bare handed.  Allow cooling period before working on equipment.  To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns. MOVING PARTS can injure.  Keep away from moving parts such as fans.  Keep all doors, panels, covers, and guards closed and securely in place.  Have only qualified persons remove doors, panels, covers, or guards for maintenance and troubleshooting as necessary.  Reinstall doors, panels, covers, or guards when maintenance is finished and before reconnecting input power.

Read Instructions.

 Read and follow all labels and the Owner’s Manual carefully before installing, operating, or servicing unit. Read the safety information at the beginning of the manual and in each section.  Use only genuine replacement parts from the manufacturer.  Perform maintenance and service according to the Owner’s Manuals, industry standards, and national, state, and local codes. FLYING METAL or DIRT can injure eyes.  Wear safety glasses with side shields or wear face shield.

Electric And Magnetic Fields (Emf)

can affect Implanted Medical Devices.  Wearers of Pacemakers and other Implanted Medical Devices should keep away.  Implanted Medical Device wearers should consult their doctor and the device manufacturer before going near arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations. OVERUSE can cause OVERHEATING.  Allow cooling period; follow rated duty cycle.  Reduce amperage (thickness) or reduce duty cycle before starting to cut again. EXPLODING HYDROGEN hazard.  When cutting aluminum underwater or with the water touching the underside of the aluminum, free hydrogen gas may collect under the work- piece.  See your cutting engineer and water table instructions for help. FALLING EQUIPMENT can injure.  Use lifting eye to lift unit only, NOT running gear, gas cylinders, or any other accessories.  Use equipment of adequate capacity to lift unit.  If using lift forks to move unit, be sure forks are long enough to ex- tend beyond opposite side of unit.  Keep equipment (cables and cords) away from moving vehicles when working from an aerial location.  Follow the guidelines in the Applications Manual for the Revised NIOSH Lifting Equation (Publication No. 94−110) when manually lifting heavy parts or equipment. FIRE OR EXPLOSION hazard.  Do not locate unit on, over, or near combustible surfaces.  Do not install unit near flammables.  Do not overload building wiring − be sure power supply system is properly sized, rated, and protected to handle this unit. STATIC (ESD) can damage PC boards.  Put on grounded wrist strap BEFORE handling boards or parts.  Use proper static-proof bags and boxes to store, move, or ship PC boards. H.F. RADIATION can cause interference.  High frequency (H.F.) can interfere with radio navigation, safety services, computers, and communications equipment.  Have only qualified persons familiar with elec- tronic equipment perform this installation.  The user is responsible for having a qualified electrician promptly correct any interference problem resulting from the installation.  If notified by the FCC about interference, stop using the equipment at once.  Have the installation regularly checked and maintained.  Keep high-frequency source doors and panels tightly shut, keep spark gaps at correct setting, and use grounding and shielding to minimize the possibility of interference. ARC CUTTING can cause interference.  Electromagnetic energy can interfere with sensitive electronic equipment such as computers and computer-driven equipment such as robots.  To reduce possible interference, keep cables as short as possible, close together, and down low, such as on the floor.  Locate cutting operation 100 meters from any sensitive electronic equipment.  Be sure this cutting power source is installed and grounded according to this manual.  If interference still occurs, the user must take extra measures such as moving the machine, using shielded cables, using line filters, or shielding the work area.

EMF Information Electric current flowing through any conductor causes localized electric and magnetic fields (EMF). Welding current creates an EMF field around the welding circuit and welding equipment. EMF fields may interfere with some medical implants, e.g. pacemakers. Protective measures for per- sons wearing medical implants have to be taken. For example, access restrictions for passers−by or individual risk assessment for welders. All welders should use the following procedures in order to minimize expos- ure to EMF fields from the welding circuit:

  • Keep cables close together by twisting or taping them, or using a
  • cable cover.
  • Do not place your body between welding cables. Arrange cables
  • to one side and away from the operator.
  • Do not coil or drape cables around your body.
  • Keep head and trunk as far away from the equipment in the weld-
  • ing circuit as possible.
  • Connect work clamp to workpiece as close to the weld as
  • possible.
  • Do not work next to, sit or lean on the welding power source.
  • Do not weld whilst carrying the welding power source or wire
  • feeder. About Implanted Medical Devices: Implanted Medical Device wearers should consult their doctor and the device manufacturer before performing or going near arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations. If cleared by your doctor, then following the above procedures is recom- mended.

Consulter les symboles et les instructions ci-dessous y afférant pour les actions nécessaires afin d’éviter le danger. 2-2. Dangers liés au coupage à l’arc au plasma Les symboles présentés ci-après sont utilisés tout au long du présent manuel pour attirer votre attention et identifier les ris- ques de danger. Lorsque vous voyez un symbole, soyez vigilant et suivez les directives mentionnées afin d’éviter tout danger. Les consignes de sécurité présentées ci-après ne font que résumer l’information contenue dans les normes de sécurité énumérées à la section 1-5. Veuillez lire et respecter toutes ces normes de sécurité. L’installation, l’utilisation, l’entretien et les réparations ne doi- vent être confiés qu’à des personnes qualifiées. Au cours de l’utilisation, tenir toute personne à l’écart et plus particulièrement les enfants. LE COUPAGE présente un risque de feu ou d’explosion. Des particules de métal chaud et des étincelles peuvent jaillir de la pièce au moment du coupage. Les étincelles et le métal chaud, la pièce à couper chauffée et l’équipement chaud peuvcnt causer un feu ou des brûlures. Avant de commencer à travailler, assurez-vous que l’endroit est sécuritaire.  Déplacez toute matière inflammable se trouvant à l’intérieur d’un périmètre de 10,7 m (35 pi) de la pièce à couper. Si cela est impos- sible, vous devez les couvrir avec des housses approuvées et bien ajustées.  Ne coupez pas dans un endroit où des étincelles pourraient attein- dre des matières inflammables.  Protégez−vous, ainsi que toute autre personne travaillant sur les lieux, contre les étincelles et le métal chaud.  Assurez−vous qu’aucune étincelle ni particule de métal ne peut se glisser dans de petites fissures ou tomber dans d’autres pièces.  Afin d’éliminer tout risque de feu, soyez vigilant et gardez toujours un extincteur à la portée de la main.  Si vous coupez sur un plafond, un plancher ou une cloison, soyez conscient que cela peut entraîner un feu de l’autre côté.  Ne coupez pas sur un contenant fermé tel qu’un réservoir ou un bi- don.  Fixez le câble de masse sur la pièce à couper, le plus près possible de la zone à couper afin de prévenir que le courant de coupage ne prenne une trajectoire inconnue ou longue et ne cause ainsi une décharge électrique, d’étincelles ou un feu.  Ne pas utiliser le coupeur plasma pour dégeler des conduites ge- lées.  Ne coupez jamais des contenants qui peuvent contenir des matiè- res inflammables. Vous devez en premier lieu les vider et les nettoyer convenablement.  Ne coupez pas quand l’atmosphère peut contenir des poussières, gaz ou vapeurs (comme l’essence) inflammables.  Ne coupez pas dans un endroit où l’atmosphère risque de contenir de la poussière ou des vapeurs explosives.  Ne coupez pas de bouteilles, de tuyaux ou de contenants pressuri- sés.  Ne coupez pas de contenants qui ont déjà reçu des combustibles.  Portez des vêtements de protection exempts d’huile tels que des gants en cuir, une veste résistante, des pantalons sans revers, des bottes et un casque.  Ne placez pas le poste sur une surface combustible ou au−dessus de celle−ci.  Une fois le travail achevé, assurez−vous qu’il ne reste aucune tra- ce d’étincelles incandescentes ni de flammes.  Utiliser exclusivement des fusibles ou coupe−circuits appropriés. Ne pas augmenter leur puissance; ne pas les ponter.  Avant le coupage, retirez tout combustible de vos poches, par exemple un briquet au butane ou des allumettes. Touching live electrical parts can cause fatal shocks or severe burns. The torch and work circuit are electrically live whenever the output is on. The input power circuit and machine internal circuits are also live when power is on. Le coupage plasma nécessite des tensions plus importantes que le soudage pour amorcer et maintenir l’arc (200 à 400VDC est typique), mais peut être utilisé avec des torches équipées de systèmes de verrouillage de sécurité qui arrêtent la machine en cas de buse desserrée ou si l’électrode touche la tuyère. Incorrectly installed or improperly grounded equipment is a hazard. UN CHOC ÉLECTRIQUE peut tuer.  Ne touchez pas aux pièces électriques sous tension.  Portez des gants isolants et des vêtements de protection secs et sans trous.  Isolez−vous de la pièce à couper et du sol en utilisant des housses ou des tapis assez grands afin d’éviter tout contact physique avec la pièce à couper ou le sol.  Ne touchez pas aux pièces du chalumeau si vous êtes en contact avec la pièce à couper ou le sol.  Mettez l’appareil hors tension avant d’effectuer la vérification, le nettoyage ou le changement d’une pièce du chalumeau.  Coupez l’alimentation d’entrée avant d’installer l’appareil ou d’ef- fectuer l’entretien. Verrouillez ou étiquetez la sortie d’alimentation selon la norme OSHA 29 CFR 1910.147 (reportez−vous aux Prin- cipales normes de sécurité).  Installez le poste correctement et mettez-le à la terre convenable- ment selon les consignes du manuel de l’opérateur et les normes nationales, provinciales et locales.  Assurez−vous que le fil de terre du cordon d’alimentation est cor- rectement relié à la borne de terre dans la boîte de coupure ou que la fiche du cordon est branchée à une prise correctement mise à la terre − vous devez toujours vérifier la mise à la terre.

    Page 10

    OM-254 193 Page 6  Avant d’effectuer les connexions d’alimentation, vous devez relier le bon fil de terre.  Les câbles doivent être exempts d’humidité, d’huile et de graisse; protégez−les contre les étincelles et les pièces métalliques chau- des.  Vérifiez fréquemment le cordon d’alimentation afin de vous assurer qu’il n’est pas altéré ou à nu, remplacez−le immédiatement s’il l’est. Un fil à nu peut entraîner la mort.  L’équipement doit être hors tension lorsqu’il n’est pas utilisé.  Vérifiez et remplacez les cosses du câble du chalumeau si elles sont usées ou altérées.  Le câble du chalumeau ne doit pas s’enrouler autour de votre corps.  Si les normes le stipulent, la pièce à couper doit être mise à la terre.  Utilisez uniquement de l’équipement en bonne condition. Réparez ou remplacez immédiatement toute pièce altérée.  Portez un harnais de sécurité si vous devez travailler au−dessus du sol.  Assurez−vous que tous les panneaux et couvercles sont correcte- ment en place.  N’essayez pas d’aller à l’encontre des systèmes de verrrouillage de sécurité ou de les contourner.  Utilisez uniquement le ou les chalumeaux recommandés dans le manuel de l’opérateur.  N’approchez pas le tube du chalumeau et l’arc pilote lorsque la gâ- chette est enfoncée.  Le câble de masse doit être pincé correctement sur la pièce à cou- per, métal contre métal (et non de telle sorte qu’il puisse se détacher), ou sur la table de travail le plus près possible de la ligne de coupage.  Isoler la pince de masse quand pas mis à la pièce pour éviter le contact avec tout objet métallique. DÉCHARGES ÉLECTRIQUES poten- tiellement mortelles. Il reste une TENSION DC NON NÉGLIGEABLE dans les sources de soudage onduleur UNE FOIS l’alimentation coupée.  Mettre l’unité hors tension, mesurer la tension des condensa- teurs d’entrée et s’assurer qu’elle est pratiquement nulle avant de toucher à l’une quelconque des pièces. Mesurer cette tension conformément aux directives énoncées à la section Entretien du manuel de l’utilisateur ou du manuel technique avant de toucher à l’une quelconque des pièces. Risque de blessure en cas

    D’Explosion Des Pièces.

     Mise sous tension, toute pièce défectueuse des sources d’alimentation de l’inverseur peut exploser ou faire exploser d’autres pièces. Pour entretenir les inverseurs, toujours porter un masque protecteur et un vêtement à man- ches longues. Le coupage plasma produit des étincelles et projec- tions de métal à très haute température. Lorsque la pièce refroidit, du laitier peut se former.

    Les

    Étincelles

    Projetées

    peuvent provoquer des blessures.  Portez une visière ou des lunettes de sécurité avec des écrans la- téraux approuvées.  Portez des vêtements de protection adéquats afin de protéger vo- tre peau.  Ayez recours à des protège−tympans ou à un serre−tête ignifuges afin d’éviter que les étincelles n’entrent dans vos oreilles. Les rayons d’arc provenant du procédé de coupage produisent des rayons visibles et invisibles intenses (ultraviolets et infrarouges) qui peuvent entraîner des brûlures aux yeux et à la peau. LES RAYONS D’ARC peuvent entraî- ner des brûlures aux yeux et à la peau.  Une protection faciale (casque ou masque) avec des lunettes filt- rantes de teinte adéquate est indispensable pour protéger le visage et les yeux des rayonnements de l’arc et des étincelles pendant la découpe ou en regardant simplement ANSI Z49.1 (re- portez−vous aux Principales normes de sécurité) suggère d’utiliser un filtre de teinte n 9 (n 8 étant le minimum) pour tout travail de coupage faisant appel à un courant de moins de 300 A. On mentionne également dans la norme Z49.1 qu’un filtre plus fai- ble peut être utilisé lorsque l’arc est caché par la pièce à couper. Comme cela est habituellement le cas pour les travaux de coupage à faible courant, les teintes énumérées au tableau 1 sont fournies à titre d’information pour l’opérateur.  Porter des lunettes de sécurité à coques latérales sous votre cas- que ou écran facial.  Ayez recours à des écrans protecteurs ou à des rideaux pour pro- téger les autres contre les rayonnements, les étincelles et les éblouissements; prévenez toute personne sur les lieux de ne pas regarder l’arc.  Portez des vêtements confectionnés avec des matières résistan- tes et ignifuges (cuir, coton lourd ou laine) et des bottes de protection. Tableau 1. Protection des yeux pour le coupage au plasma d’arc Intensité de courant en ampères Filtre de teinte (minimum) Moins de 20 no. 4 20 − 40 no. 5 40 − 60 no. 6 60 − 100 no. 8 Certaines applications de coupage produisent un bruit constant, ce qui peut endommager l’ouïe si le niveau sonore dépasse les limites permises par l’OSHA (reportez−vous aux Principales normes de sécurité). LE BRUIT peut endommager l’ouïe.  Utilisez des protège−tympans ou un serre−tête antibruit si le ni- veau sonore est élevé.  Prévenez toute personne sur les lieux du danger relié au bruit. LES FUMÉES ET LES GAZ peuvent être dangereux. Le coupage produit des vapeurs et des gaz. Respirer ces vapeurs et ces gaz peut être dangereux pour la santé.  Ne mettez pas votre tête au−dessus des vapeurs. Ne respirez pas ces vapeurs.  Si vous êtes à l’intérieur au moment du coupage, ventilez la pièce ou ayez recours à une ventilation aspirante installée près de l’arc pour évacuer les vapeurs et les gaz.  Si la ventilation est médiocre, utilisez un respirateur anti−vapeurs approuvé.  Lire et comprendre les spécifications de sécurité des matériaux (MSDS) et les instructions du fabricant concernant les métaux, les consommables, les revêtements, les nettoyants et les dégrais- seurs.  Travaillez dans un espace restreint uniquement s’il est bien ventilé ou si vous portez un respirateur anti−vapeurs. Les vapeurs cau- sées par le coupage et l’épuisement de l’oxygène peuvent altérer la qualité de l’air et entraîner des blessures ou la mort. Assurez−vous que l’air ambiant est sain pour la santé.

    Page 11

    OM-254 193 Page 7  Ne coupez pas dans un endroit près d’opérations de décapage, de nettoyage ou de vaporisation. La chaleur et les rayons d’arc peu- vent réagir avec les vapeurs et former des gaz hautement toxiques et irritants.  Ne coupez pas des métaux enrobés tels que des métaux galvani- sés, contenant du plomb ou de l’acier plaqué au cadmium, à moins que l’enrobage ne soit ôté de la surface du métal à couper, que l’en- droit où vous travaillez ne soit bien ventilé, ou que vous ne portiez un respirateur anti−vapeurs. Les enrobages ou tous métaux qui contiennent ces éléments peuvent créer des vapeurs toxiques s’ils sont coupés.  Ne coupez pas de contenants qui renferment ou ont renfermés des matières toxiques ou réactives − vous devez en premier lieu les vi- der et les nettoyer convenablement. L’ARC PLASMA peut provoquer des blessures. La chaleur dégagée par le plasma d’arc peut entraîner de sérieuses brûlures. La force de l’arc est un facteur qui s’ajoute au danger de brûlures. La chaleur intense et la puissance de l’arc peuvent rapidement passer au travers de gants et de tissus.  N’approchez pas le tube du chalumeau.  Ne saisissez pas la pièce à couper près de la ligne de coupage.  L’arc pilote peut causer des brûlures − n’approchez pas le tube du chalumeau lorsque vous avez appuyé sur le gâchette.  Portez des vêtements de protection adéquats qui recouvrent tout votre corps.  Ne pointez pas le chalumeau en direction de votre corps ni de la pièce à couper lorsque vous appuyez sur la gâchette − l’arc pilote s’allume automatiquement.  Mettez l’alimentation hors tension et débranchez le cordon d’ali- mentation avant de démonter le chalumeau ou de changer une pièce du chalumeau.  Utilisez uniquement le ou les chalumeaux recommandés dans le manuel de l’opérateur. Les bouteilles de gaz contiennent du gaz sous haute pression. Si une bouteille est endommagée, elle peut exploser. Puisque les bouteilles de gaz font habituellement partie d’un processus de travail des métaux, assurez−vous de les manipuler correctement. LES BOUTEILLES peuvent exploser si elles sont endommagées.  Protégez les bouteilles de gaz comprimé contre la chaleur excessi- ve, les chocs mécaniques, des dommages physiques, le laitier, la flamme, les étincelles et l’arc.  Installez et attachez les bouteilles dans la position verticale à l’aide d’une chaîne, sur un support stationnaire ou un châssis porte−bou- teille afin de prévenir qu’elles ne tombent ou ne basculent.  Les bouteilles ne doivent pas être près de la zone de coupage ni de tout autre circuit électrique.  Un contact électrique ne doit jamais se produire entre un chalu- meau de plasma d’arc et une bouteille.  Ne coupez jamais sur une bouteille pressurisée − une explosion en résulterait.  Utilisez uniquement des bouteilles de gaz, des détendeurs, des boyaux et des raccords conçus pour l’application déterminée. Gar- dez−les, ainsi que toute autre pièce associée, en bonne condition.  Détournez votre visage du détendeur−régulateur lorsque vous ou- vrez la soupape de la bouteille.  Le couvercle du détendeur doit toujours être en place, sauf lorsque vous utilisez la bouteille ou qu’elle est reliée pour usage ultérieur.  Utiliser les équipements corrects, les bonnes procédures et suffi- samment de personnes pour soulever et déplacer les bouteilles.  Lire et suivre les instructions sur les bouteilles de gaz comprimé, l’équipement connexe et le dépliant P-1 de la CGA (Compressed Gas Association) mentionné dans les principales normes de sécu- rité. 2-3. Dangers supplémentaires en relation avec l’installation, le fonctionnement et la maintenance LES PIÈCES CHAUDES peuvent provoquer des brûlures.  Ne pas toucher des parties chaudes à mains nues.  Prévoir une période de refroidissement avant d’utiliser l’équipement.  Ne pas toucher aux pièces chaudes, utiliser les outils recom- mandés et porter des gants de soudage et des vêtements épais pour éviter les brûlures. Les

    Pièces

    Mobiles

    peuvent provoquer des blessures.  S’abstenir de toucher des organes mobiles tels que des ventilateurs.  Maintenir fermés et verrouillés les portes, pan- neaux, recouvrements et dispositifs de protec- tion.  Lorsque cela est nécessaire pour des travaux d’entretien et de dépannage, faire retirer les portes, panneaux, recouvrements ou dispositifs de protection uniquement par du personnel qua- lifié.  Remettre les portes, panneaux, recouvrements ou dispositifs de protection quand l’entretien est terminé et avant de rebrancher l’alimentation électrique.

    Lire Les Instructions.

     Lire et appliquer les instructions sur les étiquettes et le Mode d’emploi avant l’instal- lation, l’utilisation ou l’entretien de l’appareil. Lire les informations de sécurité au début du manuel et dans chaque section.  N’utiliser que les pièces de rechange recommandées par le constructeur.  Effectuer l’entretien en respectant les manuels d’utilisation, les normes industrielles et les codes nationaux, d’état et locaux. DES PIECES DE METAL ou DES SA- LETES peuvent provoquer des bles- sures dans les yeux.  Porter des lunettes de sécurité avec écrans latéraux ou un écran facial.

    Page 12

    OM-254 193 Page 8 Les CHAMPS ÉLECTROMAGNÉTIQUES (CEM) peuvent affecter les implants médicaux.  Les porteurs de stimulateurs cardiaques et autres implants médicaux doivent rester à distance.  Les porteurs d’implants médicaux doivent consulter leur médecin et le fabricant du dispositif avant de s’approcher de la zone où se déroule du soudage à l’arc, du soudage par points, du gougeage, de la découpe plasma ou une opération de chauffage par induction. L’EMPLOI EXCESSIF peut

    Surchauffer L’Équipement.

     Prévoir une période de refroidissement; re- specter le cycle opératoire nominal.  Réduire l’ampérage (épaisseur) avant de con- tinuer à couper ou réduire le facteur de marche. Danger D’EXPLOSION

    D’Hydrogène.

     Lors du coupage d’aluminium partiellement ou totalement immergé dans l’eau, de l’hydrogène libre peut s’accumuler sous la pièce.  Consultez votre ingénieur de coupage et les instructions de la table de coupage. LA CHUTE DE L’ÉQUIPEMENT peut provoquer des blessures.  Utiliser l’anneau de levage uniquement pour soulever l’appareil, NON PAS les chariot, les bouteilles de gaz ou tout autre accessoire.  Utiliser un engin d’une capacité appropriée pour soulever l’appareil.  En utilisant des fourches de levage pour déplacer l’unité, s’assu- rer que les fourches sont suffisamment longues pour dépasser du côté opposé de l’appareil.  Tenir l’équipement (câbles et cordons) à distance des véhicules mobiles lors de toute opération en hauteur.  Suivre les consignes du Manuel des applications pour l’équation de levage NIOSH révisée (Publication Nº94–110) lors du levage manuelle de pièces ou équipements lourds. Risque D’INCENDIE OU

    D’Explosion.

     Ne pas placer l’appareil sur, au-dessus ou à proximité de surfaces infllammables.  Ne pas installer l’appareil à proximité de pro- duits inflammables  Ne pas surcharger l’installation électrique − s’assurer que l’alimen- tation est correctement dimensionné et protégé avant de mettre l’appareil en service.

    Les

    Charges

    Électrostati-

    QUES peuvent endommager les cir- cuits imprimés.  Etablir la connexion avec la barrette de terre avant de manipuler des cartes ou des pièces.  Utiliser des pochettes et des boîtes antistatiques pour stocker, déplacer ou expédier des cartes PC.

    Le Rayonnement Haute Fré-

    QUENCE (H.F.) risque de provoquer des interférences.  Le Rayonnement haute frequence (H.F.) peut provoquer des interférences avec les équipe- ments de radio−navigation et de communica- tion, les services de sécurité et les ordinateurs.  Demander seulement à des personnes qualifiées familiarisées avec des équipements électroniques de faire fonctionner l’installa- tion.  L’utilisateur est tenu de faire corriger rapidement par un électricien qualifié les interférences résultant de l’installation.  Si le FCC signale des interférences, arrêter immédiatement l’appa- reil.  Effectuer régulièrement le contrôle et l’entretien de l’installation.  Maintenir soigneusement fermés les portes et les panneaux des sources de haute fréquence, maintenir les éclateurs à une distan- ce correcte et utiliser une terre et et un blindage pour réduire les interférences éventuelles. LE COUPAGE Ã L’ARC peut causer des interférence.  L’énergie électromagnétique peut gêner le fonctionnement d’appareils électroniques comme des ordinateurs et des robots.  Pour réduire la possibilité d’interférence, maintenir les câbles aussi courts que possible, les grouper, et les poser aussi bas que possi- ble (ex. par terre).  Veiller à couper à une distance de 100 mètres de tout équipement électronique sensible.  S’assurer que la source de coupage est correctement branchée et mise à la terre.  Si l’interférence persiste, l’utilisateur doit prendre des mesures supplémentaires comme écarter la machine, utiliser des câbles blindés de des filtres, ou boucler la zone de travail.

Informations relatives aux CEM Le courant électrique qui traverse tout conducteur génère des champs électromagnétiques (CEM) à certains endroits. Le courant de soudage crée un CEM autour du circuit et du matériel de soudage. Les CEM peuvent créer des interférences avec certains implants médicaux comme des stimulateurs cardiaques. Des mesures de protection pour les porteurs d’implants médicaux doivent être prises: par exemple, des restrictions d’accès pour les passants ou une évaluation individuelle des risques pour les soudeurs. Tous les soudeurs doivent appliquer les procédures suivantes pour minimiser l’exposition aux CEM provenant du circuit de soudage:

  • Rassembler les câbles en les torsadant ou en les attachant avec
  • du ruban adhésif ou avec une housse.
  • Ne pas se tenir au milieu des câbles de soudage. Disposer les
  • câbles d’un côté et à distance de l’opérateur.
  • Ne pas courber et ne pas entourer les câbles autour de votre
  • corps.
  • Maintenir la tête et le torse aussi loin que possible du matériel du
  • circuit de soudage.
  • Connecter la pince sur la pièce aussi près que possible de la
  • soudure.
  • Ne pas travailler à proximité d’une source de soudage, ni
  • s’asseoir ou se pencher dessus.
  • Ne pas souder tout en portant la source de soudage ou le
  • dévidoir. En ce qui concerne les implants médicaux : Les porteurs d’implants doivent d’abord consulter leur médecin avant de s’approcher des opérations de soudage à l’arc, de soudage par points, de gougeage, du coupage plasma ou de chauffage par induction. Si le médecin approuve, il est recommandé de suivre les procédures précé- dentes.

Electrical Service Guide Failure to follow these electrical service guide recommendations could create an electric shock or fire hazard. These recommendations are for a dedicated circuit sized for the rated output and duty cycle of the welding power source. In dedicated circuit installations, the National Electrical Code (NEC) allows the receptacle or conductor rating to be less than the rating of the circuit protection device. All components of the circuit must be physically compatible. See NEC articles 210.21, 630.11, and 630.12. NOTICE − Actual input voltage should not be 10% less than minimum and/or 10% more than maximum input voltages listed in table. If actual input voltage is outside this range, output may not be be available. 50/60 Hz Single Phase Input Voltage (V) 120 240 Input Amperes (A) At Rated Output A 15 or 20 ampere individual branch circuit protected by time-delay fuses or circuit breaker is required.

Plasma Cutting System Practices Pulling rather than pushing the torch makes cutting easier. Use a proper guide or template for accurate cutting operations. ! The pilot arc starts immediately when trigger is pressed. Maintain approximately a 90° angle to the workpiece surface for proper cutting results. Always connect work clamp to a clean, paint-free location on workpiece, as close to cutting area as possible. 90° DO NOT start pilot arc without cutting or gouging as this shortens the service life of the nozzle and electrode. Sparks should pass through the workpiece and out the bottom when cutting. If sparks flare back from surface, this usually is an indication that either travel speed is too fast or amperage is set too low. When doing extended (non-shielded) cutting, maintain approximately 1/16 in. standoff between electrode and surface. 1/16 in. (1.6 mm) DO NOT put pressure on shield when drag cutting; instead, slide shield along the surface for proper cutting results. Wt

    OM-254 193 Page 29 7-7. Checking/Replacing Retaining Cup, Tip, And Electrode ! Overtightening will strip threads. Do not overtighten retaining cup during assembly. Do not cross-thread parts causing stripping. Use care during torch assembly and parts replacement. ! Inspect shield cup, tip, and electrode for wear before cutting or whenever cutting speed has been signifi- cantly reduced. Do not operate torch without a tip or electrode in place. Be sure to use genuine replacement parts.  A good practice is to replace both the tip and electrode at the same time. Ref. 253554-A Turn Off power source. 1 Shield Cup Remove shield cup. Check cup for cracks, and replace if necessary. 2 Tip 3 Opening Remove tip. Check tip, and replace if open- ing is deformed or 50% oversize. If inside of tip is not clean and bright, clean with steel wool. Be sure to remove any pieces of steel wool afterwards. 4 Electrode Check electrode. If center has a pit more than a 1/16 in. (2 mm) deep, remove and re- place electrode. 5 Swirl Ring Remove swirl ring.
