Section 1 − Safety Precautions - Read Before Using

OM- 253086 Page 2 Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. FUMES AND GASES can be hazardous.  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. The recommended way to determine adequate ventilation is to sample for the composition and quantity of fumes and gases to which personnel are exposed.  If ventilation is poor, wear an approved air-supplied respirator.  Read and understand the Safety Data Sheets (SDSs) and the manufacturer’s instructions for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.  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 body protection made from durable, flame−resistant mate- rial (leather, heavy cotton, wool). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap. 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 containers that have held combustibles, or on closed containers such as tanks, drums, or pipes unless they are properly prepared according to AWS F4.1 and AWS A6.0 (see Safety Standards).  Do not weld where the atmosphere can 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 body protection made from durable, flame−resistant material (leather, heavy cotton, wool). Body protection includes oil-free clothing 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.  Read and understand the Safety Data Sheets (SDSs) and the manufacturer’s instructions for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals. 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 compressed gas supply when not in use.  Always ventilate confined spaces or use approved air-supplied respirator.

OM- 253086 Page 3 1-3. Additional Symbols For Installation, Operation, And Maintenance FIRE OR EXPLOSION hazard.  Do not install or place 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. 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 and support unit.  If using lift forks to move unit, be sure forks are long enough to extend 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 manu- ally lifting heavy parts or equipment. OVERUSE can cause OVERHEATING  Allow cooling period; follow rated duty cycle.  Reduce current or reduce duty cycle before starting to weld again.  Do not block or filter airflow to unit. FLYING SPARKS can injure.  Wear a face shield to protect eyes and face.  Shape tungsten electrode only on grinder with proper guards in a safe location wearing proper face, hand, and body protection.  Sparks can cause fires — keep flammables away. 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. MOVING PARTS can injure.  Keep away from moving parts.  Keep away from pinch points such as drive rolls. WELDING WIRE can injure.  Do not press gun trigger until instructed to do so.  Do not point gun toward any part of the body, other people, or any metal when threading welding wire. BATTERY EXPLOSION can injure.  Do not use welder to charge batteries or jump start vehicles unless it has a battery charging feature designed for this purpose. 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.

EMF Information Electric current flowing through any conductor causes localized electric and magnetic fields (EMF). The current from arc welding (and allied pro- cesses including spot welding, gouging, plasma arc cutting, and induction heating operations) creates an EMF field around the welding circuit. EMF fields can interfere with some medical implants, e.g. pace- makers. Protective measures for persons wearing medical implants have to be taken. For example, restrict access for passers−by or con- duct individual risk assessment for welders. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit:

Section 2 − Consignes De Sécurité − Lire Avant Utilisation

OM-253086 Page 6 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. Pour déterminer la bonne ventilation, il est recommandé de procéder à un prélèvement pour la composition et la quantité de fumées et de gaz auxquels est exposé le personnel.  Si la ventilation est médiocre, porter un respirateur anti-vapeurs approuvé.  Lire et comprendre les fiches de données de sécurité et les instruc- tions du fabricant concernant les adhésifs, les revêtements, les nettoyants, les consommables, les produits de refroidissement, les dégraisseurs, les flux et les métaux.  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 intenses (ultraviolets e infrarouges) susceptibles de provoquer des brûlures 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 un équipement de protection pour le corps fait d’un matériau résistant et ignifuge (cuir, coton robuste, laine). La protection du corps comporte des vêtements sans huile comme par ex. des gants de cuir, une chemise solide, des pantalons sans revers, des chaussures hautes et une casquette. 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 incen- dies et des brûlures. Le contact accidentel de l’électrode avec des objets métalliques peut provoquer des étincelles, une explosion, un sur- chauffement 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 et AWS A6.0 (voir les Normes de Sécurité).  Ne pas souder là où l’air ambiant pourrait contenir des poussières, gaz ou émanations 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 un équipement de protection pour le corps fait d’un matériau résistant et ignifuge (cuir, coton robuste, laine). La protection du corps comporte des vêtements sans huile comme par ex. des gants de cuir, une chemise solide, des pantalons sans revers, des chaussures hautes et une casquette.  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.  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.  Lire et comprendre les fiches de données de sécurité et les instruc- tions du fabricant concernant les adhésifs, les revêtements, les nettoyants, les consommables, les produits de refroidissement, les dégraisseurs, les flux et les métaux. 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 ref- roidissement des soudures, elles risquent de projeter du laitier.  Porter des lunettes de sécurité avec écrans latéraux ou un écran facial.

OM-253086 Page 7 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. Les bouteilles de gaz comprimé contiennent du gaz sous haute pression. Si une bouteille est endommagée, 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 comprimé, régulateurs, tuyaux et raccords convenables pour cette application spécifique; les maintenir ainsi que les éléments associés en bon état.  Tourner le dos à la sortie de vanne lors de l’ouverture de la vanne de la bouteille. Ne pas se tenir devant ou derrière le régulateur lors de l’ouverture de la vanne.  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 sécurité. 2-3. Dangers supplémentaires en relation avec l’installation, le fonctionnement et la maintenance Risque D’INCENDIE OU D’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’assurer 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 EXCESSIF peut

Section 15 − Selecting And Preparing A Tungsten

For Dc Or Ac Welding With Inverter Machines

OM-253086 Page 69 15-2. Preparing Tungsten Electrode For DC Electrode Negative (DCEN) Welding Or AC Welding With Inverter Machines Grinding the tungsten electrode produces dust and flying sparks which can cause injury and start fires. Use local exhaust (forced ventilation) at the grinder or wear an approved respirator. Read MSDS for safety information. Consider using tungsten containing ceria, lanthana, or yttria instead of thoria. Grinding dust from thoriated electrodes contains low-level radioactive material. Properly dispose of grinder dust in an environmentally safe way. Wear proper face, hand, and body protection. Keep flammables away. Ideal Tungsten Preparation − Stable Arc 1 Grinding Wheel Grind end of tungsten on fine grit, hard abrasive wheel before welding. Do not use wheel for other jobs or tungsten can become contaminated causing lower weld quality. 2 Tungsten Electrode A 2% ceriated tungsten is recommended. 3 Ideal Grind Angle Range: 15° to 30°  30 degrees is the recommended elec- trode grind angle. 4 Straight Ground Grind lengthwise, not radial. 1 3 Causes Wandering Arc 2 Wrong Tungsten Radial Grinding Preparation 15° to 30° 4 1-1/2 To 4 Times Electrode Diameter Notes
