10 totalWhat is the Miller Matic 211 and what welding processes does it support?
The Miller Matic 211 Auto-Set w/MVP is an arc welding power source and wire feeder that supports both MIG (GMAW) welding and Flux Cored (FCAW) welding processes. It features Auto-Set technology with a Multi-Voltage Plug (MVP) for flexible power input options.
What are the specifications and power requirements for the Miller Matic 211?
The Miller Matic 211 is available in two configurations: 120 VAC (90A @ 20V DC, 20% duty cycle) and 230 VAC (150A @ 23.5V DC, 30% duty cycle). The 120V model requires a 20-ampere individual branch circuit with time-delay fuses, while the 230V model requires proper electrical service setup as detailed in Section 4-8. Both models weigh 74 lbs and have identical dimensions of 17-1/2 x 10-5/8 x 15-3/4 inches.
How do I install and thread welding wire in the Miller Matic 211?
To thread welding wire, first lay the gun cable straight and pull/hold the wire while cutting off the end. Remove the gun nozzle and contact tip, then open the pressure assembly. Push wire through guides into the gun while holding it, ensuring proper drive roll positioning. Feed wire to check drive roll pressure and tighten the knob to prevent slipping. Then cut off wire, close the door, turn on power, and press the gun trigger until wire exits the gun. Finally, reinstall the contact tip and nozzle.
What should I do if the Miller Matic 211 overheats or if the over-temperature light flashes?
If the unit overheats, the thermostat opens, output stops, and the cooling fan runs. Allow the fan to run with the gun trigger switch off; the thermostat will close when the unit has cooled. The 120V model has a 20% duty cycle (3 minutes welding, 7 minutes resting) and the 230V model has a 30% duty cycle (2 minutes welding, 8 minutes resting). Wait fifteen minutes for the unit to cool and reduce amperage or duty cycle before resuming welding.
How do I set up the Auto-Set feature on the Miller Matic 211?
To use Auto-Set mode, rotate the Wire Speed control into the blue/green area corresponding to your weld wire diameter (.030 or .035), and the Auto-Set light will turn on. Then rotate the Voltage control inside the blue/green scale for the applicable material thickness (24 gauge to 3/8 inch), and the unit will automatically provide the appropriate voltage for the selected wire diameter and material thickness.
What are the proper polarity and cable connections for MIG and flux-cored welding?
For GMAW (MIG) welding with solid wire and shielding gas, use DCEP (Reverse polarity) with the gun cable connected to the positive (+) terminal and work cable to the negative (−) terminal. For FCAW (Flux-Cored) self-shielding wire with no gas, use DCEN (Straight polarity) with the gun cable connected to the negative (−) terminal and work cable to the positive (+) terminal. Always follow the wire manufacturer's recommended polarity.

Section 1 − Safety Precautions - Read Before Using
som _2010−03 7 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. Arc Welding 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. ELECTRIC SHOCK can kill. Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit is electrically live whenever the output is on. The input power circuit and machine internal circuits are also live when power is on. In semiautomatic or automatic wire welding, the wire, wire reel, drive roll housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is a hazard. 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 use AC output in damp areas, if movement is confined, or if there is a danger of falling. Use AC output ONLY if required for the welding process. If AC output is required, use remote output control if present on unit. Additional safety precautions are required when any of the follow- ing electrically hazardous conditions are present: in damp locations or while wearing wet clothing; on metal structures such as floors, gratings, or scaffolds; when in cramped positions such as sitting, kneeling, or lying; or when there is a high risk of unavoid- able or accidental contact with the workpiece or ground. For these conditions, use the following equipment in order presented: 1) a semiautomatic DC constant voltage (wire) welder, 2) a DC manual (stick) welder, or 3) an AC welder with reduced open-circuit volt- age. In most situations, use of a DC, constant voltage wire welder is recommended. And, do not work alone! Disconnect input power or stop engine before installing or servicing this equipment. Lockout/tagout input power according to OSHA 29 CFR 1910.147 (see Safety Standards). Properly install and ground this equipment according to its Owner’s Manual and national, state, and local codes. Always verify the supply ground − 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. When making input connections, attach proper grounding conduc- tor first − double-check connections. 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 − replace cord immediately if damaged − bare wiring can kill. Turn off all equipment when not in use. Do not use worn, damaged, undersized, or poorly spliced cables. Do not drape cables over your body. If earth grounding of the workpiece is required, ground it directly with a separate cable. Do not touch electrode if you are in contact with the work, ground, or another electrode from a different machine. Do not touch electrode holders connected to two welding ma- chines at the same time since double open-circuit voltage will be present. Use only well-maintained equipment. Repair or replace damaged parts at once. Maintain unit according to manual. Wear a safety harness if working above floor level. Keep all panels and covers securely in place. Clamp work cable with good metal-to-metal contact to workpiece or worktable as near the weld as practical. Insulate work clamp when not connected to workpiece to prevent contact with any metal object. Do not connect more than one electrode or work cable to any single weld output terminal. SIGNIFICANT DC VOLTAGE exists in inverter weld- ing power sources AFTER removal of inputpower. Turn Off inverter, disconnect input power, and discharge input capacitors according to instructions in Maintenance Section before touching any parts. HOT PARTS can burn. Do not touch hot parts bare handed. Allow cooling period before working on equip- ment. To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. FUMES AND GASES can be hazardous.OM-239 988 Page 2 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 welding 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 instructions for metals, consumables, coatings, cleaners, and degreasers. Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Always have a trained watch- person nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the breath- ing air is safe. Do not weld in locations near degreasing, cleaning, or spraying op- erations. The heat and rays of the arc can react with vapors to form highly toxic and irritating gases. Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless the coating is removed from the weld 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 if welded. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off from the weld. Wear an approved welding helmet fitted with a proper shade of filter lenses to protect your face and eyes from arc rays and sparks when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards). Wear approved safety glasses with side shields under your helmet. 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. ARC RAYS can burn eyes and skin. Welding on closed containers, such as tanks, drums, or pipes, can cause them to blow up. Sparks can fly off from the welding arc. The flying sparks, hot workpiece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire. Check and be sure the area is safe before doing any welding. WELDING can cause fire or explosion. Remove all flammables within 35 ft (10.7 m) of the welding arc. If this is not possible, tightly cover them with approved covers. Do not weld where flying sparks can strike flammable material. Protect yourself and others from flying sparks and hot metal. Be alert that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Watch for fire, and keep a fire extinguisher nearby. Be aware that welding on a ceiling, floor, bulkhead, or partition can cause fire on the hidden side. Do not weld on closed containers such as tanks, drums, or pipes, unless they are properly prepared according to AWS F4.1 (see Safety Standards). Do not weld where the atmosphere may contain flammable dust, gas, or liquid vapors (such as gasoline). Connect work cable to the work as close to the welding area as practical to prevent welding current from traveling long, possibly unknown paths and causing electric shock, sparks, and fire hazards. Do not use welder to thaw frozen pipes. Remove stick electrode from holder or cut off welding wire at contact tip when not in use. Wear oil-free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap. Remove any combustibles, such as a butane lighter or matches, from your person before doing any welding. 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. FLYING METAL or DIRT can injure eyes. Welding, chipping, wire brushing, and grinding cause sparks and flying metal. As welds cool, they can throw off slag. Wear approved safety glasses with side shields even under your welding helmet. BUILDUP OF GAS can injure or kill. Shut off shielding gas supply when not in use. Always ventilate confined spaces or use approved air-supplied respirator.

can affect ImplantedMedical 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. NOISE can damage hearing. Noise from some processes or equipment can damage hearing. Wear approved ear protection if noise level is high. Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylinders are normally part of the welding process, 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 flames, sparks, and arcs. Install cylinders in an upright position by securing to a stationary support or cylinder rack to prevent falling or tipping. Keep cylinders away from any welding or other electrical circuits. Never drape a welding torch over a gas cylinder. Never allow a welding electrode to touch any cylinder. Never weld on a pressurized cylinder − explosion will result. Use only correct shielding gas cylinders, regulators, hoses, and fit- tings designed 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 num- ber of persons to lift and move cylinders. Read and follow instructions on compressed gas cylinders, associated equipment, and Compressed Gas Association (CGA) publication P-1 listed in Safety Standards.OM-239 988 Page 3 1-3.

Dangers relatifs au soudage à l’arc Les symboles représentés ci-dessous sont utilisés dans ce ma- nuel pour attirer l’attention et identifier les dangers possibles. En présence de l’un de ces symboles, prendre garde et suivre les instructions afférentes pour éviter tout risque. Les instructions en matière de sécurité indiquées ci-dessous ne constituent qu’un sommaire des instructions de sécurité plus complètes fournies dans les normes de sécurité énumérées dans la Sec- tion 2-5. Lire et observer toutes les normes de sécurité. Seul un personnel qualifié est autorisé à installer, faire fonc- tionner, entretenir et réparer cet appareil. Pendant le fonctionnement, maintenir à distance toutes les personnes, notamment les enfants de l’appareil. UNE DÉCHARGE ÉLECTRIQUE peut entraîner la mort. Le contact d’organes électriques sous tension peut provoquer des accidents mortels ou des brûlures graves. Le circuit de l’électrode et de la pièce est sous tension lorsque le courant est délivré à la sortie. Le circuit d’alimentation et les circuits inter- nes de la machine sont également sous tension lorsque l’alimentation est sur Marche. Dans le mode de soudage avec du fil, le fil, le dérouleur, le bloc de commande du rouleau et toutes les parties métalli- ques en contact avec le fil sont sous tension électrique. Un équipement installé ou mis à la terre de manière incorrecte ou impropre constitue un danger. Ne pas toucher aux pièces électriques sous tension. Porter des gants isolants et des vêtements de protection secs et sans trous. S’isoler 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 pas se servir de source électrique à courant électrique dans les zones humides, dans les endroits confinés ou là où on risque de tomber. Se servir d’une source électrique à courant électrique UNIQUE- MENT si le procédé de soudage le demande. Si l’utilisation d’une source électrique à courant électrique s’avère nécessaire, se servir de la fonction de télécommande si l’appareil en est équipé. D’autres consignes de sécurité sont nécessaires dans les condi- tions suivantes : risques électriques dans un environnement humide ou si l’on porte des vêtements mouillés ; sur des structures métalliques telles que sols, grilles ou échafaudages ; en position coincée comme assise, à genoux ou couchée ; ou s’il y a un risque élevé de contact inévitable ou accidentel avec la pièce à souder ou le sol. Dans ces conditions, utiliser les équipements suivants, dans l’ordre indiqué : 1) un poste à souder DC à tension constante (à fil), 2) un poste à souder DC manuel (électrode) ou 3) un poste à souder AC à tension à vide réduite. Dans la plupart des situations, l’utilisation d’un poste à souder DC à fil à tension constante est re- commandée. En outre, ne pas travailler seul ! Couper l’alimentation ou arrêter le moteur avant de procéder à l’in- stallation, à la réparation ou à l’entretien de l’appareil. Déverrouiller l’alimentation selon la norme OSHA 29 CFR 1910.147 (voir nor- mes de sécurité). Installer le poste correctement et le mettre à la terre convenable- ment selon les consignes du manuel de l’opérateur et les normes nationales, provinciales et locales. Toujours vérifier la terre du cordon d’alimentation. Vérifier et s’assurer que le fil de terre du cordon d’alimentation est bien raccordé à la borne de terre du sectionneur ou que la fiche du cordon est raccordée à une prise correctement mise à la terre. En effectuant les raccordements d’entrée, fixer d’abord le conduc- teur de mise à la terre approprié et contre-vérifier les connexions. Les câbles doivent être exempts d’humidité, d’huile et de graisse; protégez−les contre les étincelles et les pièces métalliques chaudes. Vérifier fréquemment le cordon d’alimentation afin de s’assurer qu’il n’est pas altéré ou à nu, le remplacer 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. Ne pas utiliser des câbles usés, endommagés, de grosseur insuffi- sante ou mal épissés. Ne pas enrouler les câbles autour du corps. Si la pièce soudée doit être mise à la terre, le faire directement avec un câble distinct. Ne pas toucher l’électrode quand on est en contact avec la pièce, la terre ou une électrode provenant d’une autre machine. Ne pas toucher des porte électrodes connectés à deux machines en même temps à cause de la présence d’une tension à vide dou- blée. N’utiliser qu’un matériel en bon état. Réparer ou remplacer sur-le- champ les pièces endommagées. Entretenir l’appareil conformé- ment à ce manuel. Porter un harnais de sécurité si l’on doit travailler au-dessus du sol. S’assurer que tous les panneaux et couvercles sont correctement en place. Fixer le câble de retour de façon à obtenir un bon contact métal- métal avec la pièce à souder ou la table de travail, le plus près pos- sible de la soudure. Isoler la pince de masse quand pas mis à la pièce pour éviter le contact avec tout objet métallique. Ne pas raccorder plus d’une électrode ou plus d’un câble de masse à une même borne de sortie de soudage.OM-239 988 Page 6 Il reste une TENSION DC NON NÉGLIGEABLE dans les sources de soudage onduleur UNE FOIS l’alimentation coupée. Arrêter les convertisseurs, débrancher le courant électrique et décharger les condensateurs d’alimentation selon les instructions indiquées dans la partie Entretien avant de toucher les pièces. LES PIÈCES CHAUDES peuvent provoquer des brûlures. Ne pas toucher à mains nues les parties chaudes. Prévoir une période de refroidissement avant de travailler à l’équipement. Ne pas toucher aux pièces chaudes, utiliser les outils recomman- dés et porter des gants de soudage et des vêtements épais pour éviter les brûlures. LES FUMÉES ET LES GAZ peuvent être dangereux. Le soudage génère des fumées et des gaz. Leur inhalation peut être dangereux pour votre santé. Eloigner votre tête des fumées. Ne pas respirer les fumées. À l’intérieur, ventiler la zone et/ou utiliser une ventilation forcée au niveau de l’arc pour l’évacuation des fumées et des gaz de soudage. Si la ventilation est médiocre, porter 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. Travailler dans un espace fermé seulement s’il est bien ventilé ou en portant un respirateur à alimentation d’air. Demander toujours à un surveillant dûment formé de se tenir à proximité. Des fumées et des gaz de soudage peuvent déplacer l’air et abaisser le niveau d’oxygène provoquant des blessures ou des accidents mortels. S’assurer que l’air de respiration ne présente aucun danger. Ne pas souder dans des endroits situés à proximité d’opérations de dégraissage, de nettoyage ou de pulvérisation. La chaleur et les rayons de l’arc peuvent réagir en présence de vapeurs et for- mer des gaz hautement toxiques et irritants. Ne pas souder des métaux munis d’un revêtement, tels que l’acier galvanisé, plaqué en plomb ou au cadmium à moins que le revête- ment n’ait été enlevé dans la zone de soudure, que l’endroit soit bien ventilé, et en portant un respirateur à alimentation d’air. Les revêtements et tous les métaux renfermant ces éléments peuvent dégager des fumées toxiques en cas de soudage. LES RAYONS DE L’ARC peuvent provoquer des brûlures dans les yeux et sur la peau. Le rayonnement de l’arc du procédé de soudage génère des rayons visibles et invisibles intense (ultraviolets et infrarouges) susceptibles de provoquer des brûlure dans les yeux et sur la peau. Des étincelles sont projetées pendant le soudage. Porter un casque de soudage approuvé muni de verres filtrants approprié pour protéger visage et yeux pour protéger votre visage et vos yeux pendant le soudage ou pour regarder (voir ANSI Z49.1 et Z87.1 énuméré dans les normes de sécurité). Porter des lunettes de sécurité avec écrans latéraux même sous votre casque. Avoir recours à des écrans protecteurs ou à des rideaux pour protéger les autres contre les rayonnements les éblouissements et les étincelles ; prévenir toute personne sur les lieux de ne pas regarder l’arc. Porter des vêtements confectionnés avec des matières résistan- tes et ignifuges (cuir, coton lourd ou laine) et des bottes de protection. LE SOUDAGE peut provoquer un incendie ou une explosion. Le soudage effectué sur des conteneurs fermés tels que des réservoirs, tambours ou des conduites peut provoquer leur éclatement. Des étincelles peuvent être projetées de l’arc de soudure. La projection d’étincelles, des pièces chaudes et des équipements chauds peut provoquer des incendies et des brûlures. Le contact accidentel de l’électrode avec des objets métalliques peut provoquer des étincelles, une explosion, un surchauffement ou un incendie. Avant de commencer le soudage, vérifier et s’assurer que l’endroit ne présente pas de danger. Déplacer toutes les substances inflammables à une distance de 10,7 m de l’arc de soudage. En cas d’impossibilité les recouvrir soigneusement avec des protections homologués. Ne pas souder dans un endroit là où des étincelles peuvent tomber sur des substances inflammables. Se protéger et d’autres personnes de la projection d’étincelles et de métal chaud. Des étincelles et des matériaux chauds du soudage peuvent facilement passer dans d’autres zones en traversant de petites fissures et des ouvertures. Surveiller tout déclenchement d’incendie et tenir un extincteur à proximité. Le soudage effectué sur un plafond, plancher, paroi ou séparation peut déclencher un incendie de l’autre côté. Ne pas effectuer le soudage sur des conteneurs fermés tels que des réservoirs, tambours, ou conduites, à moins qu’ils n’aient été préparés correctement conformément à AWS F4.1 (voir les nor- mes de sécurité). Ne soudez pas si l’air ambiant est chargé de particules, gaz, ou va- peurs inflammables (vapeur d’essence, par exemple). Brancher le câble de masse sur la pièce le plus près possible de la zone de soudage pour éviter le transport du courant sur une longue distance par des chemins inconnus éventuels en provo- quant des risques d’électrocution, d’étincelles et d’incendie. Ne pas utiliser le poste de soudage pour dégeler des conduites ge- lées. En cas de non utilisation, enlever la baguette d’électrode du porte- électrode ou couper le fil à la pointe de contact. Porter des vêtements de protection dépourvus d’huile tels que des gants en cuir, une chemise en matériau lourd, des pantalons sans revers, des chaussures hautes et un couvre chef. Avant de souder, retirer toute substance combustible de vos po- ches telles qu’un allumeur au butane ou des allumettes. Une fois le travail achevé, assurez−vous qu’il ne reste aucune trace d’étincelles incandescentes ni de flammes. Utiliser exclusivement des fusibles ou coupe−circuits appropriés. Ne pas augmenter leur puissance; ne pas les ponter. Une fois le travail achevé, assurez−vous qu’il ne reste aucune trace d’étincelles incandescentes ni de flammes. Utiliser exclusivement des fusibles ou coupe−circuits appropriés. Ne pas augmenter leur puissance; ne pas les ponter. Suivre les recommandations dans OSHA 1910.252(a)(2)(iv) et NFPA 51B pour les travaux à chaud et avoir de la surveillance et un extincteur à proximité. DES PIECES DE METAL ou DES SALETES peuvent provoquer des blessures dans les yeux. Le soudage, l’écaillement, le passage de la pièce à la brosse en fil de fer, et le meulage génèrent des étincelles et des particules métalliques volantes. Pendant la période de refroidissement des soudures, elles risquent de projeter du laitier. Porter des lunettes de sécurité avec écrans latéraux ou un écran facial.

risquent de provoquer des blessures ou même la mort. Fermer l’alimentation du gaz protecteur en cas de non-utilisation. Veiller toujours à bien aérer les espaces confi- nés ou se servir d’un respirateur d’adduction d’air homologué. 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. LE BRUIT peut endommager l’ouïe. Le bruit des processus et des équipements peut affecter l’ouïe. Porter des protections approuvées pour les oreilles si le niveau sonore est trop élevé. Des bouteilles de gaz protecteur contiennent du gaz sous haute pression. Si une bouteille est endom- magée, elle peut exploser. Du fait que les bouteilles de gaz font normalement partie du procédé de soudage, les manipuler avec précaution. LES BOUTEILLES peuvent exploser si elles sont endommagées. Protéger les bouteilles de gaz comprimé d’une chaleur excessive, des chocs mécaniques, des dommages physiques, du laitier, des flammes ouvertes, des étincelles et des arcs. Placer les bouteilles debout en les fixant dans un support station- naire ou dans un porte-bouteilles pour les empêcher de tomber ou de se renverser. Tenir les bouteilles éloignées des circuits de soudage ou autres circuits électriques. Ne jamais placer une torche de soudage sur une bouteille à gaz. Une électrode de soudage ne doit jamais entrer en contact avec une bouteille. Ne jamais souder une bouteille pressurisée − risque d’explosion. Utiliser seulement des bouteilles de gaz protecteur, régulateurs, tuyaux et raccords convenables pour cette application spécifique ; les maintenir ainsi que les éléments associés en bon état. Détourner votre visage du détendeur-régulateur lorsque vous ouvrez la soupape de la bouteille. Le couvercle du détendeur doit toujours être en place, sauf lorsque la bouteille est utilisée 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 Risque D’INCENDIE OUD’Explosion.
Ne pas placer l’appareil sur, au-dessus ou à proximité de surfaces inflammables. Ne pas installer l’appareil à proximité de pro- duits inflammables. Ne pas surcharger l’installation électrique − s’assurer que l’alimentation est correctement dimensionnée et protégée avant de mettre l’appareil en service. LA CHUTE DE L’ÉQUIPEMENT peut provoquer des blessures. Utiliser l’anneau de levage uniquement pour soulever l’appareil, NON PAS les chariots, les bouteilles de gaz ou tout autre accessoire. Utiliser un équipement de levage de capacité suffisante pour lever 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.L’Emploi

peuvent provoquer des blessures. Porter un écran facial pour protéger le visage et les yeux. Affûter l’électrode au tungstène uniquement à la meuleuse dotée de protecteurs. Cette manœuvre est à exécuter dans un endroit sûr lorsque l’on porte l’équipement homologué de protection du visage, des mains et du corps. Les étincelles risquent de causer un incendie − éloigner toute sub- stance inflammable.Les Charges Électrostati-
QUES peuvent endommager les cir- cuits imprimés. Établir la connexion avec la barrette de terre avant de manipuler des cartes ou des pièces. Utiliser des pochettes et des boîtes antista- tiques pour stocker, déplacer ou expédier des cartes de circuits imprimes.OM-239 988 Page 8 Les PIÈCES MOBILES peuvent causer des blessures. Ne pas s’approcher des organes mobiles. Ne pas s’approcher des points de coincement tels que des rouleaux de commande. LES FILS DE SOUDAGE peuvent provoquer des blessures. Ne pas appuyer sur la gâchette avant d’en avoir reçu l’instruction. Ne pas diriger le pistolet vers soi, d’autres personnes ou toute pièce mécanique en engageant le fil de soudage. Les PIÈCES MOBILES peuvent causer des blessures. S’abstenir de toucher des organes mobiles tels que des ventilateurs. Maintenir fermés et verrouillés les portes, panneaux, recouvrements et dispositifs de protection. 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.Le
Rayonnement

Fréquence
(H.F.)
risque de provoquer des interférences. Le rayonnement haute fréquence (H.F.) peut provoquer des interférences avec les équi- pements de radio−navigation et de com- munication, les services de sécurité et les ordi- nateurs. 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’ap- pareil. 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 un blindage pour réduire les interférences éventuelles. LE SOUDAGE À L’ARC risque de provoquer des interférences. L’énergie électromagnétique risque de provoquer des interférences pour l’équipement électronique sensible tel que les ordinateurs et l’équipement commandé par ordinateur tel que les robots. Veiller à ce que tout l’équipement de la zone de soudage soit compatible électromagnétiquement. Pour réduire la possibilité d’interférence, maintenir les câbles de soudage aussi courts que possible, les grouper, et les poser aussi bas que possible (ex. par terre). Veiller à souder à une distance de 100 mètres de tout équipe- ment électronique sensible. Veiller à ce que ce poste de soudage soit posé et mis à la terre conformément à ce mode d’emploi. En cas d’interférences après avoir pris les mesures précéden- tes, il incombe à l’utilisateur de prendre des mesures supplé- mentaires telles que le déplacement du poste, l’utilisation de câ- bles blindés, l’utilisation de filtres de ligne ou la pose de protec- teurs dans la zone de travail. 2-4.

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:

Use shorter electrode extension (stickout). Workpiece dirty. Remove all grease, oil, moisture, rust, paint, undercoating, and dirt from work surface before welding. Insufficient shielding gas at welding arc. Increase flow of shielding gas at regulator/flowmeter and/or prevent drafts near welding arc. Dirty welding wire. Use clean, dry welding wire. Eliminate pickup of oil or lubricant on welding wire from feeder or liner. Incorrect polarity. Check polarity required by welding wire, and change to correct polarity at welding power source. 8-9. Troubleshooting − Porosity Porosity − small cavities or holes resulting from gas pockets in weld metal.S-0635
Possible Causes Corrective Actions Insufficient shielding gas at welding arc. Increase flow of shielding gas at regulator/flowmeter and/or prevent drafts near welding arc. Remove spatter from gun nozzle. Check gas hoses for leaks. Place nozzle 1/4 to 1/2 in. (6-13 mm) from workpiece. Hold gun near bead at end of weld until molten metal solidifies. Wrong gas. Use welding grade shielding gas; change to different gas. Dirty welding wire. Use clean, dry welding wire. Eliminate pick up of oil or lubricant on welding wire from feeder or liner. Workpiece dirty. Remove all grease, oil, moisture, rust, paint, coatings, and dirt from work surface before welding. Use a more highly deoxidizing welding wire (contact supplier). Welding wire extends too far out of nozzle. Be sure welding wire extends not more than 1/2 in. (13 mm) beyond nozzle. 8-10. Troubleshooting − Excessive Penetration Good Penetration Excessive Penetration − weld metal melting through base metal and hanging underneath weld. Excessive PenetrationS-0639
Possible Causes Corrective Actions Excessive heat input. Select lower voltage range and reduce wire feed speed. Increase travel speed.OM-239 988 Page 40 8-11. Troubleshooting − Lack Of Penetration Lack Of Penetration − shallow fusion between weld metal and base metal. Lack of Penetration Good Penetration
S-0638
Possible Causes Corrective Actions Improper joint preparation. Material too thick. Joint preparation and design must provide access to bottom of groove while maintaining proper welding wire extension and arc characteristics. Improper weld technique. Maintain normal gun angle of 0 to 15 degrees to achieve maximum penetration. Keep arc on leading edge of weld puddle. Be sure welding wire extends not more than 1/2 in. (13 mm) beyond nozzle. Insufficient heat input. Select higher wire feed speed and/or select higher voltage range. Reduce travel speed. Incorrect polarity. Check polarity required by welding wire, and change to correct polarity at welding power source. 8-12. Troubleshooting − Incomplete Fusion Incomplete Fusion − failure of weld metal to fuse completely with base metal or a preceeding weld bead.S-0637
Possible Causes Corrective Actions Workpiece dirty. Remove all grease, oil, moisture, rust, paint, undercoating, and dirt from work surface before welding. Insufficient heat input. Select higher voltage range and/or adjust wire feed speed. Improper welding technique. Place stringer bead in proper location(s) at joint during welding. Adjust work angle or widen groove to access bottom during welding. Momentarily hold arc on groove side walls when using weaving technique. Keep arc on leading edge of weld puddle. Use correct gun angle of 0 to 15 degrees. 8-13. Troubleshooting − Burn-Through Burn-Through − weld metal melting completely through base metal resulting in holes where no metal remains.S-0640
Possible Causes Corrective Actions Excessive heat input. Select lower voltage range and reduce wire feed speed. Increase and/or maintain steady travel speed.OM-239 988 Page 41 8-14. Troubleshooting − Waviness Of Bead Waviness Of Bead − weld metal that is not parallel and does not cover joint formed by base metal.
S-0641
Possible Causes Corrective Actions Welding wire extends too far out of nozzle. Be sure welding wire extends not more than 1/2 in. (13 mm) beyond nozzle. Unsteady hand. Support hand on solid surface or use two hands. 8-15. Troubleshooting − Distortion Distortion − contraction of weld metal during welding that forces base metal to move. Base metal moves in the direction of the weld bead.S-0642
Possible Causes Corrective Actions Excessive heat input. Use restraint (clamp) to hold base metal in position. Make tack welds along joint before starting welding operation. Select lower voltage range and/or reduce wire feed speed. Increase travel speed. Weld in small segments and allow cooling between welds.OM-239 988 Page 42 8-16.

8-17. Troubleshooting Guide For Semiautomatic Welding Equipment Problem Probable Cause Remedy Wire feed motor operates, but wire does not feed. Too little pressure on wire feed rolls. Increase pressure setting on wire feed rolls. Incorrect wire feed rolls. Check size stamped on wire feed rolls, replace to match wire size and type if necessary. Wire spool brake pressure too high. Decrease brake pressure on wire spool. Restriction in the gun and/or assembly. Check and replace cable, gun, and contact tip if damaged. Check size of contact tip and cable liner, replace if necessary. Wire curling up in front of the wire feed rolls (bird nesting). Too much pressure on wire feed rolls. Decrease pressure setting on wire feed rolls. Incorrect cable liner or gun contact tip size. Check size of contact tip and check cable liner length and diameter, replace if necessary. Gun end not inserted into drive housing properly. Loosen gun securing bolt in drive housing and push gun end into housing just enough so it does not touch wire feed rolls. Dirty or damaged (kinked) liner. Replace liner. Wire feeds, but no gas flows. Gas cylinder empty. Replace empty gas cylinder. Gas nozzle plugged. Clean or replace gas nozzle. Gas cylinder valve not open or flowmeter not adjusted. Open gas valve at cylinder and adjust flow rate. Restriction in gas line. Check gas hose between flowmeter and wire feeder, and gas hose in gun and cable assembly. Loose or broken wires to gas solenoid. Have Factory Authorized Service Agent repair wiring. Gas solenoid valve not operating. Have Factory Authorized Service Agent replace gas solenoid valve. Incorrect primary voltage connected to welding power source. Check primary voltage and relink welding power source for correct voltage.OM-239 988 Page 43 Problem Remedy Probable Cause Welding arc not stable. Wire slipping in drive rolls. Adjust pressure setting on wire feed rolls. Replace worn drive rolls if necessary. Wrong size gun liner or contact tip. Match liner and contact tip to wire size and type. Incorrect voltage setting for selected wire feed speed on welding power source. Readjust welding parameters. Loose connections at the gun weld cable or work cable. Check and tighten all connections.
