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 explained 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 symbols 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 1-7. 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 following 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 unavoidable 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 voltage. 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). 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 conductor first − double-check connections. Keep cords dry, free of oil and grease, and protected from hot metal and sparks. Frequently inspect input power cord and ground conductor for damage or bare wiring – replace immediately if damaged – bare wiring can kill. Turn off all equipment when not in use. Do not use worn, damaged, undersized, or repaired 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. Use only well-maintained equipment. Repair or replace damaged parts at once. Maintain unit according to manual. Do not touch electrode holders connected to two welding machines at the same time since double open-circuit voltage will be present. 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. Disconnect cable for process not in use. Use GFCI protection when operating auxiliary equipment. Do not test or reset GFCI receptacles at idle speed/low voltage or the GFCI will be damaged and not provide protection from electric shock caused by a ground fault. SIGNIFICANT DC VOLTAGE exists in inverter power sources AFTER stopping engine. Stop engine on inverter 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 equipment. To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns. Properly install, ground, and operate this equipment according to its Owner’s Manual and national, state, and local codes. OM-267 212 Page 1 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. FUMES AND hazardous. GASES can be Welding 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 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 watchperson nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the breathing air is safe. Do not weld in locations near degreasing, cleaning, or spraying operations. 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. 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. ARC RAYS can burn eyes and skin. 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 material (leather, heavy cotton, wool). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap. WELDING can cause fire or explosion. 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. 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. OM-267 212 Page 2 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 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 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 bypass 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. NOISE can damage hearing. Noise from some processes or equipment can damage hearing. Wear approved ear protection if noise level is high. 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. CYLINDERS can explode if damaged. Compressed 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. Protect compressed gas cylinders from excessive heat, mechanical 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 compressed gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them and associated parts in good condition. Turn face away from valve outlet when opening cylinder valve. Do not stand in front of or behind the regulator when opening the 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, associated equipment, and Compressed Gas Association (CGA) publication P-1 listed in Safety Standards. 1-3. Engine Hazards BATTERY EXPLOSION can injure. Always wear a face shield, rubber gloves, and protective clothing when working on a battery. Stop engine before disconnecting or connecting battery cables, battery charging cables (if applicable), or servicing battery. Do not allow tools to cause sparks when working on a battery. Do not use welder to charge batteries or jump start vehicles unless the unit has a battery charging feature designed for this purpose. Observe correct polarity (+ and −) on batteries. Disconnect negative (−) cable first and connect it last. Keep sparks, flames, cigarettes, and other ignition sources away from batteries. Batteries produce explosive gases during normal operation and when being charged. Follow battery manufacturer’s instructions when working on or near a battery. FUEL can cause fire or explosion. Stop engine and let it cool off before checking or adding fuel. Do not add fuel while smoking or if unit is near any sparks or open flames. Do not overfill tank — allow room for fuel to expand. Do not spill fuel. If fuel is spilled, clean up before starting engine. Dispose of rags in a fireproof container. Always keep nozzle in contact with tank when fueling. MOVING PARTS can injure. Keep away from moving parts such as fans, belts, and rotors. Keep all doors, panels, covers, and guards closed and securely in place. Stop engine before installing or connecting unit. Have only qualified persons remove doors, panels, covers, or guards for maintenance and troubleshooting as necessary. To prevent accidental starting during servicing, disconnect negative (−) battery cable from battery. Keep hands, hair, loose clothing, and tools away from moving parts. Reinstall doors, panels, covers, or guards when servicing is finished and before starting engine. Before working on generator, remove spark plugs or injectors to keep engine from kicking back or starting. Block flywheel so that it will not turn while working on generator components. EXHAUST SPARKS can cause fire. Do not let engine exhaust sparks cause fire. Use approved engine exhaust spark arrestor in required areas — see applicable codes. 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. STEAM AND HOT COOLANT can burn. If possible, check coolant level when engine is cold to avoid scalding. Always check coolant level at overflow tank, if present on unit, instead of radiator (unless told otherwise in maintenance section or engine manual). If the engine is warm, checking is needed, and there is no overflow tank, follow the next two statements. Wear safety glasses and gloves and put a rag over radiator cap. Turn cap slightly and let pressure escape slowly before completely removing cap. Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell. NEVER use inside a home or garage, EVEN IF doors and windows are open. Only use OUTSIDE and far away from windows, doors, and vents. BATTERY ACID can BURN SKIN and EYES. Do not tip battery. Replace damaged battery. Flush eyes and skin immediately with water. ENGINE HEAT can cause fire. Do not locate unit on, over, or near combustible surfaces or flammables. Keep exhaust and exhaust pipes way from flammables. 1-4. Compressed Air Hazards COMPRESSED AIR EQUIPMENT can injure or kill. Incorrect installation or operation of this unit could result in equipment failure and personal injury. Only qualified persons should install, operate, and service this unit according to its Owner’s Manual, industry standards, and national, state, and local codes. Do not exceed the rated output or capacity of the compressor or any equipment in the compressed air system. Design compressed air system so failure of any component will not put people or property at risk. Before working on compressed air system, turn off and lockout/ tagout unit, release pressure, and be sure air pressure cannot be accidentally applied. Do not work on compressed air system with unit running unless you are a qualified person and following the manufacturer’s instructions. Do not modify or alter compressor or manufacturer-supplied equipment. Do not disconnect, disable, or override any safety equipment in the compressed air system. Use only components and accessories approved by the manufacturer. Keep away from potential pinch points or crush points created by equipment connected to the compressed air system. Do not work under or around any equipment that is supported only by air pressure. Properly support equipment by mechanical means. OM-267 212 Page 3 HOT METAL from air arc cutting and gouging can cause fire or explosion. Do not cut or gouge near flammables. Watch for fire; keep extinguisher nearby. COMPRESSED AIR can injure or kill. Before working on compressed air system, turn off and lockout/tagout unit, release pressure, and be sure air pressure cannot be accidentally applied.

EMF Information Electric current flowing through any conductor causes localized electric and magnetic fields (EMF). The current from arc welding (and allied processes including spot welding, gouging, plasma arc cutting, and induction heating operations) creates an EMF field around the welding circuit. EMF fields may interfere with some medical implants, e.g. pacemakers. Protective measures for persons wearing medical implants have to be taken. For example, restrict access for passers−by or conduct individual risk assessment for welders. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit: 1. Keep cables close together by twisting or taping them, or using a cable cover. 2. Do not place your body between welding cables. Arrange cables to one side and away from the operator. 3. Do not coil or drape cables around your body. OM-267 212 Page 6 4. Keep head and trunk as far away from the equipment in the welding circuit as possible. 5. Connect work clamp to workpiece as close to the weld as possible. 6. Do not work next to, sit or lean on the welding power source. 7. 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 recommended.

Dangers relatifs au soudage à l’arc Les symboles présentés ci-après sont utilisés tout au long du présent manuel pour attirer votre attention et identifier les risques 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 2-7. Veuillez lire et respecter toutes ces normes de sécurité. L’installation, l’utilisation, l’entretien et les réparations ne doivent être confiés qu’à des personnes qualifiées. Au cours de l’utilisation, tenir toute personne à l’écart et plus particulièrement les enfants. UN CHOC ÉLECTRIQUE peut tuer. Un simple contact avec des pièces électriques peut provoquer une électrocution ou des blessures graves. L’électrode et le circuit de soudage sont sous tension dès que l’appareil est sur ON. Le circuit d’entrée et les circuits internes de l’appareil sont également sous tension à ce moment-là. En soudage semi-automatique ou automatique, le fil, le dévidoir, le logement des galets d’entraînement et les pièces métalliques en contact avec le fil de soudage sont sous tension. Des matériels mal installés ou mal mis à la terre présentent un danger. Ne jamais toucher les pièces électriques sous tension. Porter des gants et des vêtements de protection secs ne comportant pas de trous. S’isoler de la pièce et de la terre au moyen de tapis ou d’autres moyens isolants suffisamment grands pour empêcher le contact physique éventuel avec la pièce ou la terre. 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 UNIQUEMENT 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. Des précautions de sécurité supplémentaires sont requises dans des environnements à risque comme: les endroits humides ou lorsque l’on porte des vêtements mouillés; sur des structures métalliques au sol, grillages et échafaudages; dans des positions assises, à genoux et allongées; ou quand il y a un risque important de contact accidentel avec la pièce ou le sol. Dans ces cas utiliser les appareils suivants dans l’ordre de préférence: 1) un poste à souder DC semi−automatique de type CV (MIG/MAG), 2) un poste à souder manuel (électrode enrobée) DC, 3) un poste à souder manuel AC avec tension à vide réduite. Dans la plupart des cas, un poste courant continu de type CV est recommandé. Et, ne pas travailler seul! Couper l’alimentation ou arrêter le moteur avant de procéder à l’installation, à la réparation ou à l’entretien de l’appareil. Déverrouiller l’alimentation selon la norme OSHA 29 CFR 1910.147 (voir normes de sécurité). Installez, mettez à la terre et utilisez correctement cet équipement conformément à son Manuel d’Utilisation et aux réglementations nationales, gouvernementales et locales. Installer et mettre à la terre correctement cet appareil conformément à son manuel d’utilisation et aux codes nationaux, provinciaux et municipaux. 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 conducteur 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 et le conducteur de mise à la terre afin de s’assurer qu’il n’est pas altéré ou dénudé −, le remplacer immédiatement s’il l’est −. Un fil dénudé peut entraîner la mort. Mettre l’appareil hors tension quand on ne l’utilise pas. Ne pas utiliser des câbles usés, endommagés, sous dimensionnés ou réparés. 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 utiliser le connecteur de pièce ou le câble de retour. 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 doublée. N’utiliser qu’un matériel en bon état. Réparer ou remplacer sur-le-champ les pièces endommagées. Entretenir l’appareil conformément à ce manuel. Porter un harnais de sécurité quand on travaille en hauteur. Maintenir solidement en place tous les panneaux et capots. Fixer le câble de retour de façon à obtenir un bon contact métalmétal avec la pièce à souder ou la table de travail, le plus près possible 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. Débrancher le câble pour le procédé non utilisé. OM-267 212 Page 7 Utiliser une protection différentielle lors de l’utilisation d’un équipement auxiliaire. Ne pas tester ni réarmer les prises femelles avec différentiel au régime de ralenti/en basse tension: cela endommagerait le disjoncteur différentiel, qui ne remplirait plus son rôle de protection contre une électrocution causée par un défaut de masse. Il reste une TENSION DC NON NÉGLIGEABLE dans les sources de soudage onduleur UNE FOIS le moteur coupé. Couper l’alimentation du poste et décharger les condensateurs d’entrée comme indiqué dans la Section Maintenance avant de toucher des composants. 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 recommandés et porter des gants de soudage et des vêtements épais pour éviter les brûlures. 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. 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 instructions 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 former 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 revêtement 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. OM-267 212 Page 8 LES ACCUMULATIONS DE GAZ risquent de provoquer des blessures ou même la mort. Fermer l’alimentation du gaz comprimé en cas de non utilisation. Veiller toujours à bien aérer les espaces confinés ou se servir d’un respirateur d’adduction d’air homologué. 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 et 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 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 et AWS A6.0 (voir les Normes de Sécurité). Ne soudez pas si l’air ambiant est chargé de particules, gaz, ou vapeurs 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 provoquant des risques d’électrocution, d’étincelles et d’incendie. Ne pas utiliser le poste de soudage pour dégeler des conduites gelées. En cas de non utilisation, enlever la baguette d’électrode du porteélectrode 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 poches 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. LE BRUIT peut affecter l’ouïe. Le bruit des processus et des équipements peut affecter l’ouïe. Porter des protections approuvés pour les oreilles si le niveau sonore est trop élevé. 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. Si des BOUTEILLES sont endommagées, elles pourront exploser. Des bouteilles de gaz comprimé protecteur 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. 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 stationnaire 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. Maintenir le chapeau de protection sur la soupape, sauf en cas d’utilisation ou de branchement de la bouteille. Utiliser les équipements corrects, les bonnes procédures et suffisamment 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 existant en relation avec le moteur L’EXPLOSION DE LA BATTERIE peut provoquer des blessures. Toujours porter une protection faciale, des gants en caoutchouc et vêtements de protection lors d’une intervention sur la batterie. Arrêter le moteur avant de débrancher ou de brancher des câbles de batterie, des câbles de chargeur de batterie (le cas échéant) ou de batterie d’entretien. Eviter de provoquer des étincelles avec les outils en travaillant sur la batterie. Ne pas utiliser l’appareil de soudage pour charger des batteries ou faire démarrer des véhicules à l’aide de câbles de démarrage, sauf si l’appareil dispose d’une fonctionnalité de charge de batterie destinée à cet usage. Observer la polarité correcte (+ et −) sur les batteries. Débrancher le câble négatif (–) en premier lieu. Le rebrancher en dernier lieu. Les sources d’étincelles, flammes nues, cigarettes et autres sources d’inflammation doivent être maintenues à l’écart des batteries. Ces dernières produisent des gaz explosifs en fonctionnement normal et en cours de charge. Respecter les consignes du fabricant de la batterie pour travailler sur une batterie ou à proximité. LE CARBURANT MOTEUR peut provoquer un incendie ou une explosion. Arrêter le moteur avant de vérifier le niveau de carburant ou de faire le plein. Ne pas faire le plein en fumant ou proche d’une source d’étincelles ou d’une flamme nue. Ne pas faire le plein de carburant à ras bord; prévoir de l’espace pour son expansion. Faire attention de ne pas renverser de carburant. Nettoyer tout carburant renversé avant de faire démarrer le moteur. Jeter les chiffons dans un récipient ignifuge. Toujours garder le pistolet en contact avec le réservoir lors du remplissage. Les PIÈCES MOBILES peuvent causer des blessures. S’abstenir de toucher des parties mobiles telles que des ventilateurs, courroies et rotors. Maintenir fermés et verrouillés les portes, panneaux, recouvrements et dispositifs de protection. Arrêter le moteur avant d’installer ou brancher l’appareil. 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 qualifié. OM-267 212 Page 9 Pour empêcher tout démarrage accidentel pendant les travaux d’entretien, débrancher le câble négatif (−) de batterie de la borne. Ne pas approcher les mains, cheveux, vêtements lâches et outils des organes mobiles. Remettre en place les portes, panneaux, recouvrements ou dispositifs de protection à la fin des travaux d’entretien et avant de mettre le moteur en marche. Avant d’intervenir, déposer les bougies ou injecteurs pour éviter la mise en route accidentelle du moteur. Bloquer le volant moteur pour éviter sa rotation lors d’une intervention sur le générateur. LES ÉTINCELLES À L’ÉCHAPPEMENT peuvent provoquer un incendie. Empêcher les étincelles d’échappement du moteur de provoquer un incendie. Utiliser uniquement un pare-étincelles approuvé − voir codes en vigueur. LES PIÈCES CHAUDES peuvent provoquer des brûlures. Ne pas toucher des parties chaudes à mains nues. Prévoir une période de refroidissement avant de travailler à l’équipement. Ne pas toucher aux pièces chaudes, utiliser les outils recommandés et porter des gants de soudage et des vêtements épais pour éviter les brûlures. LA VAPEUR ET LE LIQUIDE DE REFROIDISSEMENT CHAUD peuvent provoquer des brûlures. Il est préférable de vérifier le liquide de refroidissement une fois le moteur refroidi pour éviter de se brûler. Toujours vérifier le niveau de liquide de refroidissement dans le vase d’expansion (si présent), et non dans le radiateur (sauf si précisé autrement dans la section maintenance du manuel du moteur). Si le moteur est chaud et que le liquide doit être vérifié, opérer comme suivant. Mettre des lunettes de sécurité et des gants, placer un torchon sur le bouchon du radiateur. Dévisser le bouchon légèrement et laisser la vapeur s’échapper avant d’enlever le bouchon. L’utilisation d’un groupe autonome à l’intérieur PEUT VOUS TUER EN QUELQUES MINUTES. Les fumées d’un groupe autonome contient du monoxyde de carbone. C’est un poison invisible et inodore. JAMAIS utiliser dans une maison ou garage, même avec les portes et fenêtres ouvertes.

Informations relatives aux CEM Le courant électrique qui traverse tout conducteur génère des champs électromagnétiques (CEM) à certains endroits. Le courant issu d’un soudage à l’arc (et de procédés connexes, y compris le soudage par points, le gougeage, le découpage plasma et les opérations de chauffage par induction) crée un champ électromagnétique (CEM) autour du circuit de soudage. 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: 1. Rassembler les câbles en les torsadant ou en les attachant avec du ruban adhésif ou avec une housse. 2. Ne pas se tenir au milieu des câbles de soudage. Disposer les câbles d’un côté et à distance de l’opérateur. 3. Ne pas courber et ne pas entourer les câbles autour de votre corps. 4. Maintenir la tête et le torse aussi loin que possible du matériel du circuit de soudage. 5. Connecter la pince sur la pièce aussi près que possible de la soudure. 6. Ne pas travailler à proximité d’une source de soudage, ni s’asseoir ou se pencher dessus. 7. 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 précédentes. OM-267 212 Page 13 OM-267 212 Page 14 Complete Parts List available at www.MillerWelds.com SECTION 3 − DEFINITIONS 3-1.

Stick Welding Procedure ! Weld current starts when electrode touches workpiece. ! Weld current can damage electronic parts in vehicles. Disconnect both battery cables before welding on a vehicle. Place work clamp as close to the weld as possible. Equipment Needed: Tools Needed: Always wear appropriate per1 sonal protective clothing. Workpiece Make sure workpiece is clean before welding. 2 Constant Current Welding Power Source 5 2 3 6 7 3 Electrode Before striking an arc, insert an electrode in the electrode holder. A small diameter electrode requires less current than a large one. Follow recommendations of the electrode manufacturer when setting weld amperage (see Section 13-2). 4 1 Work Clamp Place as close to the weld as possible. 4 Insulated Electrode Holder 5 Electrode Holder Position 6 Arc Length Arc length is the distance from the electrode to the workpiece. A short arc with correct amperage will give a sharp, crackling sound. Correct arc length is related to electrode diameter. Examine the weld bead to determine if the arc length is correct. Arc length for 1/16 and 3/32 in. diameter electrodes should be about 1/16 in. (1.6 mm); arc length for 1/8 and 5/32 in. electrodes should be about 1/8 in. (3 mm). 7 Slag Use a chipping hammer and wire brush to remove slag. Remove slag and check weld bead before making another weld pass. stick 2015 - 04 − 151 593 OM-267 212 Page 42 6013 7014 7018 7024 Ni-Cl 308L ALL DEEP EP ALL DEEP 6013 EP,EN ALL LOW GENERAL 7014 EP,EN ALL MED 7018 EP ALL MED SMOOTH, EASY, FAST LOW HYDROGEN, STRONG 7024 EP,EN NI-CL EP FLAT HORIZ FILLET ALL 308L EP ALL USAGE EP 6011 AC PENETRATION 3/32 1/8 5/32 3/16 7/32 1/4 1/16 5/64 3/32 1/8 5/32 3/16 7/32 1/4 3/32 1/8 5/32 3/16 7/32 1/4 3/32 1/8 5/32 3/16 7/32 1/4 3/32 1/8 5/32 3/16 7/32 1/4 3/32 1/8 5/32 3/16 3/32 1/8 5/32 DC* 6010 ELECTRODE 450 400 350 300 AMPERAGE RANGE 250 200 150 POSITION 6010 & 6011 100 50 DIAMETER ELECTRODE 13-2.

Striking an Arc 1 ! Weld current starts when electrode touches workpiece. 1 2 3 Electrode Workpiece Arc Scratch Technique 2 Drag electrode across workpiece like striking a match; lift electrode slightly after touching work. If arc goes out, electrode was lifted too high. If electrode sticks to workpiece, use a quick twist to free it. Tapping Technique 3 Bring electrode straight down to workpiece; then lift slightly to start arc. If arc goes out, electrode was lifted too high. If electrode sticks to workpiece, use a quick twist to free it. 1 2 3 S-0049 / S-0050 OM-267 212 Page 43 2 13-4. Positioning Electrode Holder 1 2 After learning to start and hold an arc, practice running beads of weld metal on flat plates using a full electrode. 1 10°-30° 90° End View Of Work Angle Side View Of Electrode Angle Hold the electrode nearly perpendicular to the work, although tilting it ahead (in the direction of travel) will be helpful. 2 90° To produce the best results, hold a short arc, travel at a uniform speed, and feed the electrode downward at a constant rate as it melts. Groove Welds 10°-30° 45° 1 2 45° Fillet Welds S-0060 13-5. Poor Weld Bead Characteristics 1 2 3 4 5 Large Spatter Deposits Rough, Uneven Bead Slight Crater During Welding Bad Overlap Poor Penetration 4 2 3 5 1 S-0053-A 13-6. Good Weld Bead Characteristics 1 2 3 Fine Spatter Uniform Bead Moderate Crater During Welding Weld a new bead or layer for each 1/8 in. (3.2 mm) thickness in metals being welded. 2 3 4 5 4 5 No Overlap Good Penetration into Base Metal 1 S-0052-B OM-267 212 Page 44 13-7. Conditions That Affect Weld Bead Shape Weld bead shape is affected by electrode angle, arc length, travel speed, and thickness of base metal. Angle Too Small Correct Angle 10° - 30° Angle Too Large Electrode Angle Drag Spatter Arc Length Too Short Normal Too Long Slow Normal Fast Travel Speed S-0061 13-8. Electrode Movement During Welding Normally, 2 1 1 2 3 3 a single stringer bead is satisfactory for most narrow groove weld joints; however, for wide groove weld joints or bridging across gaps, a weave bead or multiple stringer beads work better. Stringer Bead − Steady Movement Along Seam Weave Bead − Side to Side Movement Along Seam Weave Patterns Use weave patterns to cover a wide area in one pass of the electrode. Do not let weave width exceed 2-1/2 times diameter of electrode. S-0054-A 13-9. Welding Lap Joints 1 2 Electrode Single-Layer Fillet Weld Move electrode in circular motion. 30° Or Less 30° Or Less 1 1 2 3 Multi-Layer Fillet Weld Weld a second layer when a heavier fillet is needed. Remove slag before making another weld pass. Weld both sides of joint for maximum strength. 3 S-0063 / S-0064 OM-267 212 Page 45 2 13-10. Welding Groove (Butt) Joints 1 Tack Welds Prevent butt joint distortion by tack welding the materials in position before final weld. Workpiece distortion occurs when heat is applied locally to a joint. One side of a metal plate will “curl” up toward the weld. Distortion will also cause the edges of a butt joint to pull together ahead of the electrode as the weld cools. 1 2 1/16 in. (1.6 mm) Square Groove Weld 3 Single V-Groove Weld 4 Double V-Groove Weld Materials up to 3/16 in. (5 mm) thick can often be welded without special preparation using the square groove weld. However, when welding thicker materials it may be necessary to prepare the edges (V-groove) of butt joints to ensure good welds. 30° The single or double V-groove weld is good for materials 3/16 − 3/4 in. (5-19 mm) thick. Generally, the single V-groove is used on materials up to 3/4 in. (19 mm) thick and when, regardless of thickness, you can weld from one side only. Create a 30 degree bevel with oxyacetylene or plasma cutting equipment. Remove scale from material after cutting. A grinder can also be used to prepare bevels. 4 3 2 S-0062 13-11. Welding Tee Joints 1 2 Electrode Fillet Weld Keep arc short and move at definite rate of speed. Hold electrode as shown to provide fusion into the corner. Square edge of the weld surface. For maximum strength weld both sides of upright section. 3 1 2 45° Or Less 1 2 Multi-Layer Deposits Weld a second layer when a heavier fillet is needed. Use any of the weaving patterns shown in Section 13-8. Remove slag before making another weld pass. 3 S-0060 / S-0058-A / S-0061 OM-267 212 Page 46 13-12. Weld Test 1 2 3 Strike the weld joint in the direction shown. A good weld bends over but does not break. 3 If the weld breaks, examine it to determine the cause. If the weld is porous (many holes), the arc length was probably too long. 3 If the weld contains bits of slag, the arc may have been too long or the electrode was moved incorrectly which allowed molten slag to be trapped in the weld. This may happen on a V-groove joint made in several layers and calls for additional cleaning between layers. 2 To 3 in. (51-76 mm) 1/4 in. (6.4 mm) Vise Weld Joint Hammer 2 1 2 To 3 in. (51-76 mm) 2 1 If the original beveled surface is visible the material was not fully melted which is often caused by insufficient heat or too fast a travel speed. S-0057-B 13-13. Troubleshooting Porosity − small cavities or holes resulting from gas pockets in weld metal. Possible Causes Corrective Actions Arc length too long. Reduce arc length. Damp electrode. Use dry electrode. Workpiece dirty. Remove all grease, oil, moisture, rust, paint, coatings, slag, and dirt from work surface before welding. Excessive Spatter − scattering of molten metal particles that cool to solid form near weld bead. Possible Causes Corrective Actions Amperage too high for electrode. Decrease amperage or select larger electrode. Arc length too long or voltage too high. Reduce arc length or voltage. Incomplete Fusion − failure of weld metal to fuse completely with base metal or a preceeding weld bead. Possible Causes Corrective Actions Insufficient heat input. Increase amperage. Select larger electrode and increase amperage. 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. Workpiece dirty. Remove all grease, oil, moisture, rust, paint, coatings, slag, and dirt from work surface before welding. OM-267 212 Page 47 2 Lack Of Penetration − shallow fusion between weld metal and base metal. Lack of Penetration Good Penetration Possible Causes Corrective Actions Improper joint preparation. Material too thick. Joint preparation and design must provide access to bottom of groove. Improper weld technique. Keep arc on leading edge of weld puddle. Insufficient heat input. Increase amperage. Select larger electrode and increase amperage. Reduce travel speed. Excessive Penetration − weld metal melting through base metal and hanging underneath weld. Excessive Penetration Good Penetration Possible Causes Corrective Actions Excessive heat input. Select lower amperage. Use smaller electrode. Increase and/or maintain steady travel speed. Burn-Through − weld metal melting completely through base metal resulting in holes where no metal remains. Possible Causes Corrective Actions Excessive heat input. Select lower amperage. Use smaller electrode. Increase and/or maintain steady travel speed. Waviness Of Bead − weld metal that is not parallel and does not cover joint formed by base metal. Possible Causes Corrective Actions Unsteady hand. Use two hands. Practice technique. Distortion − contraction of weld metal during welding that forces base metal to move. Base metal moves in the direction of the weld bead. 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 amperage for electrode. Increase travel speed. Weld in small segments and allow cooling between welds.
