Symbol Usage Means Warning! Watch Out! There are possible hazards with this procedure! The possible hazards are shown in the adjoining symbols. Marks a special safety message. Means “Note”; not safety related. This group of symbols means Warning! Watch Out! possible 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 1-6. 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). 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 conductor first – double-check connections. 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. 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 inverters after stopping engine. Stop engine on inverter and discharge input capacitors according to instructions in Maintenance Section before touching any parts. FUMES AND GASES can be hazardous. 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 exhaust at the arc to remove welding fumes and gases. If ventilation is poor, use an approved air-supplied respirator. Read 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 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 if necessary, while wearing an air-supplied respirator. The coatings and any metals containing these elements can give off toxic fumes if welded. OM-4418 Page 1 BUILDUP OF GAS can injure or kill. FLYING METAL can injure eyes. Shut off shielding gas supply when not in use. Always ventilate confined spaces or use approved air-supplied respirator. 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. ARC RAYS can burn eyes and skin. HOT PARTS can cause severe burns. 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 a welding helmet fitted with a proper shade of filter 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 and glare; warn others not to watch the arc. Wear protective clothing made from durable, flame-resistant material (wool and leather) and foot protection. Allow cooling period before maintaining. Wear protective gloves and clothing when working on a hot engine. Do not touch hot engine parts or just-welded parts bare-handed. NOISE can damage hearing. Noise from some processes or equipment can damage hearing. Wear approved ear protection if noise level is high. 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. Protect yourself and others from flying sparks and hot metal. Do not weld where flying sparks can strike flammable material. Remove all flammables within 35 ft (10.7 m) of the welding arc. If this is not possible, tightly cover them with approved covers. Be alert that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. MAGNETIC FIELDS can affect pacemakers. 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). 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 and fire hazards. Do not use welder to thaw frozen pipes. Protect compressed gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs. 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. Follow requirements in OSHA 1910.252 (a) (2) (iv) and NFPA 51B for hot work and have a fire watcher and extinguisher nearby. Pacemaker wearers keep away. Wearers should consult their doctor before going near arc welding, gouging, or spot welding operations. CYLINDERS can explode if damaged. 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. 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 fittings 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. Read and follow instructions on compressed gas cylinders, associated equipment, and CGA publication P-1 listed in Safety Standards. 1-3. Engine Hazards BATTERY EXPLOSION can BLIND. FUEL can cause fire or explosion. Always wear a face shield, rubber gloves, and protective clothing when working on a battery. Stop engine before disconnecting or connecting battery cables 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. Observe correct polarity (+ and –) on batteries. Disconnect negative (–) cable first and connect it last. OM-4418 Page 2 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 cause injury. Keep away from 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 people remove guards or covers 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 panels or guards and close doors 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. 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. ENGINE EXHAUST GASES can kill. Use equipment outside in open, well-ventilated areas. If used in a closed area, vent engine exhaust outside and away from any building air intakes. 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. 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. Turn cap slightly and let pressure escape slowly before completely removing cap. 1-4. Compressed Air Hazards BREATHING COMPRESSED AIR can cause serious injury or death. Do not use compressed air for breathing. Use only for cutting, gouging, and tools. 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 cause injury. HOT PARTS can cause burns and injury. Wear approved safety goggles. Do not direct air stream toward self or others. Do not touch hot compressor or air system parts. Let system cool down before touching or servicing. TRAPPED AIR PRESSURE AND WHIPPING HOSES can cause injury. Release air pressure from tools and system before servicing, adding or changing attachments, or opening compressor oil drain or oil fill cap. READ INSTRUCTIONS. Read Owner’s Manual before using or servicing unit. Stop engine and release air pressure before servicing. 1-5. Additional Symbols For Installation, Operation, And Maintenance FALLING UNIT can cause injury. Use lifting eye to lift unit only, NOT running gear, gas cylinders, trailer, 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. OVERHEATING can damage motors. Turn off or unplug equipment before starting or stopping engine. Do not let low voltage and frequency caused by low engine speed damage electric motors. Do not connect 50 or 60 Hertz motors to the 100 Hertz receptacle where applicable. OM-4418 Page 3 FLYING SPARKS can cause injury. H.F. RADIATION can cause interference. 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. 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. 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. ARC WELDING can cause interference. TILTING OF TRAILER can cause injury. Use tongue jack or blocks to support weight. Properly install welding generator onto trailer according to instructions supplied with trailer. READ INSTRUCTIONS. Use only genuine MILLER/Hobart replacement parts. Perform engine and air compressor (if applicable) maintenance and service according to this manual and the engine/air compressor (if applicable) manuals. High-frequency (H.F.) can interfere with radio navigation, safety services, computers, and communications equipment. Have only qualified persons familiar with electronic equipment perform this installation. The user is responsible for having a qualified electrician promptly correct any interference problem resulting from the installation. If notified by the FCC about interference, stop using the equipment at once. Have the installation regularly checked and maintained. Keep high-frequency source doors and panels tightly shut, keep spark gaps at correct setting, and use grounding and shielding to minimize the possibility of interference. Electromagnetic energy can interfere with sensitive electronic equipment such as microprocessors, computers, and computer-driven equipment such as robots. Be sure all equipment in the welding area is electromagnetically compatible. To reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor. Locate welding operation 100 meters from any sensitive electronic equipment. Be sure this welding machine is installed and grounded according to this manual. If interference still occurs, the user must take extra measures such as moving the welding machine, using shielded cables, using line filters, or shielding the work area. 1-6.

EMF Information Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields Welding current, as it flows through welding cables, will cause electromagnetic fields. There has been and still is some concern about such fields. However, after examining more than 500 studies spanning 17 years of research, a special blue ribbon committee of the National Research Council concluded that: “The body of evidence, in the committee’s judgment, has not demonstrated that exposure to powerfrequency electric and magnetic fields is a human-health hazard.” However, studies are still going forth and evidence continues to be examined. Until the final conclusions of the research are reached, you may wish to minimize your exposure to electromagnetic fields when welding or cutting. OM-4418 Page 4 To reduce magnetic fields in the workplace, use the following procedures: 1. Keep cables close together by twisting or taping them. 2. Arrange cables to one side and away from the operator. 3. Do not coil or drape cables around your body. 4. Keep welding power source and cables as far away from operator as practical. 5. Connect work clamp to workpiece as close to the weld as possible. About Pacemakers: Pacemaker wearers consult your doctor first. 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 1-5. 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. En effectuant les raccordements d’entrée fixer d’abord le conducteur de mise à la terre approprié et contre-vérifier les connexions. Vérifier fréquemment le cordon d’alimentation pour voir s’il n’est pas endommagé ou dénudé – remplacer le cordon immédiatement s’il est endommagé – un câble dénudé peut provoquer une électrocution. Mettre l’appareil hors tension quand on ne l’utilise pas. Ne pas utiliser des câbles usés, endommagés, de grosseur insuffisante 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 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. N’utiliser qu’un matériel en bon état. Réparer ou remplacer sur-le-champ les pièces endommagées. Entretenir l’appareil conformément à ce manuel. 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. 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 métal-métal 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. Une tension DC importante subsiste à l’intérieur des onduleurs après avoir coupé l’alimentation. 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. LES FUMÉES ET LES GAZ peuvent être dangereux. Ne pas se servir de source électrique àcourant électrique dans les zones humides, dans les endroits confinés ou là où on risque de tomber. Le soudage génère des fumées et des gaz. Leur inhalation peut être dangereux pour votre santé. Se servir d’une source électrique àcourant électrique UNIQUEMENT si le procédé de soudage le demande. Eloigner votre tête des fumées. Ne pas respirer les fumées. Si l’utilisation d’une source électrique àcourant électrique s’avère nécessaire, se servir de la fonction de télécommande si l’appareil en est équipé. À l’interieur, ventiler la zone et/ou utiliser un échappement au niveau de l’arc pour l’évacuation des fumées et des gaz de soudage. Des précautions de sécurité supplémentaires sont requises dans des envi- Si la ventilation est insuffisante, utiliser un respirateur à alimentation d’air homologué. Lire les spécifications de sécurité des matériaux (MSDSs) et les instructions du fabricant concernant les métaux, les consommables, les revêtements, les nettoyants et les dégraisseurs. 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 si nécessaire, 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. ronnements 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). 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. Couper l’alimentation du poste et décharger les condensateurs d’entrée comme indiqué dans la Section Maintenance avant de toucher des composants. OM-4418 Page 5 LES ACCUMULATIONS DE GAZ risquent de provoquer des blessures ou même la mort. 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 PARTICULES VOLANTES peuvent blesser les yeux. Fermer l’alimentation du gaz protecteur 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 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. DES PIÈCES CHAUDES peuvent provoquer des brûlures graves. 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 muni d’un écran de filtre approprié 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 protections approuvés pour les oreilles si le niveau sondre est trop élevé. Utiliser des écrans ou des barrières pour protéger des tiers de l’éclair et de l’éblouissement; demander aux autres personnes de ne pas regarder l’arc. Porter des vêtements de protection constitué dans une matière durable, résistant au feu (laine ou cuir) et une protection des pieds. Porter des lunettes de sécurité avec écrans latéraux ou un écran facial. Prévoir une période de refroidissement avant d’effectuer des travaux d’entretien. Porter des gants et des vêtements de protection pour travailler sur un moteur chaud. Ne pas toucher à mains nues les parties chaudes du moteur ni les pièces récemment soudées. LE BRUIT peut affecter l’ouïe. Le bruit des processus et des équipements peut affecter l’ouïe. LE SOUDAGE peut provoquer un incendie ou une explosion. Porter des protections approuvés pour les oreilles si le niveau sondre est trop élevé. 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. LES CHAMPS MAGNÉTIQUES peuvent affecter les stimulateurs cardiaques. Se protéger et d’autres personnes de la projection d’étincelles et de métal chaud. Ne pas souder dans un endroit là où des étincelles peuvent tomber sur des substances inflammables. Si des BOUTEILLES sont endommagées, elles pourront exploser. 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. 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 normes de sécurité). Brancher le câble 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 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 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 poches telles qu’un allumeur au butane ou des allumettes. Porteurs de stimulateur cardiaque, restez à distance. Les porteurs d’un stimulateur cardiaque doivent d’abord consulter leur médecin avant de s’approcher des opérations de soudage à l’arc, de gougeage ou de soudage par points. Des bouteilles de gaz 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, 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 protecteur, régulateurs, tuyaux et raccords convenables pour cette application spécifique; les maintenir ainsi que les éléments associés en bon état. Ne pas tenir la tête en face de la sortie en ouvrant la soupape de la bouteille. Maintenir le chapeau de protection sur la soupape, sauf en cas d’utilisation ou de branchement de la bouteille. Lire et suivre les instructions concernant les bouteilles de gaz comprimé, les équipements associés et les publication P-1 CGA énumérées dans les normes de sécurité. 1-3. Engine Hazards LES ACCUMULATIONS DE GAZ 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 confinés ou se servir d’un respirateur d’adduction d’air homologué. OM-4418 Page 6 L’ACIDE DE LA BATTERIE peut provoquer des brûlures dans les YEUX et sur la PEAU. Ne pas renverser la batterie. Remplacer une batterie endommagée. Rincer immédiatement les yeux et la peau à l’eau. L’EXPLOSION DE LA BATTERIE peut RENDRE AVEUGLE. 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 les câbles de batterie. Eviter de provoquer des étincelles avec les outils en travaillant sur la batterie. Ne pas utiliser le poste de soudage pour charger les batteries ou des véhicules de démarrage rapide. Observer la polarité correcte (+ et –) sur les batteries. Débrancher le câble négatif (–) en premier lieu. Le rebrancher en dernier lieu. 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. 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 panneaux ou les dipositifs de protection et fermer les portes à la fin des travaux d’entretien et avant de faire démarrer le moteur. 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. LA VAPEUR ET LE LIQUIDE DE REFROIDISSEMENT CHAUD peuvent provoquer des brûlures. 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. LA CHALEUR DU MOTEUR peut provoquer un incendie. DES ORGANES MOBILES peuvent provoquer des blessures. Il est préférable de vérifier le liquide de refroidissement une fois le moteur refroidi pour éviter de se brûler. Ne pas approcher les mains des ventilateurs, courroies et autres pièces en mouvement. Maintenir fermés et fixement en place les portes, panneaux, recouvrements et dispositifs de protection. Ne pas placer l’appareil sur, au-dessus ou à proximité de surfaces inflammables. Tenir à distance les produits inflammables de l’échappement. LES ÉTINCELLES À L’ÉCHAPPEMENT peuvent provoquer un incendie. Arrêter le moteur avant d’installer ou brancher l’appareil. Demander seulement à un personnel qualifié d’enlever les dispositifs de sécurité ou les recouvrements pour effectuer, s’il y a lieu, des travaux d’entretien et de dépannage. Empêcher les étincelles d’échappement du moteur de provoquer un incendie. Utiliser uniquement un pare-étincelles approuvé – voir codes en vigueur. 1-4. Dangers liés à l’air comprimé RESPIRER L’AIR COMPRIMÉ peut provoquer des blessures graves ou causer la mort. Le METAL CHAUD lors du coupage et gougeage plasma peut provoquer un incendie ou une explosion. Ne pas utiliser l’air comprimé pour respirer. Utiliser l’air comprimé seulement pour le coupage, gougeage et les outils pneumatiques. Ne pas couper ou gouger à proximité de produits inflammables. Surveillez et garder un extincteur à proximité. L’AIR COMPRIMÉ peut provoquer des blessures. DES PIECES CHAUDES peuvent provoquer des brûlures et blessures. Porter des lunettes de sécurité approuvées. Ne pas diriger le jet d’air vers d’autres ou soi– même. Ne pas toucher le compresseur ou d’autres éléments du circuit air comprimé chauds. Laisser l’ensemble se refroidir avant de toucher ou d’effectuer la maintenance. L’AIR COMPRIME EMMAGASINE ET DES TUYAUX SOUS PRESSION peuvent provoquer des blessures. LIRE LES INSTRUCTIONS. Relâcher la pression d’air de l’outillage ou du système avant d’effectuer la maintenance, avant de changer ou de rajouter des éléments ou avant d’ouvrir la purge ou le bouchon de remplissage d’huile. Lisez le manuel d’instructions avant l’utilisation ou la maintenance de l’appareil. Arrêter le moteur et relâcher la pression avant d’effectuer la maintenance. 1-5. Dangers supplémentaires en relation avec l’installation, le fonctionnement et la maintenance LA CHUTE DE L’APPAREIL peut blesser. Utiliser l’anneau de levage uniquement pour soulever l’appareil lui-même ; sans chariot, de bouteilles de gaz, remorque, ou autres accessoires. 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. OM-4418 Page 7 LE SURCHAUFFEMENT peut endommager le moteur électrique. LIRE LES INSTRUCTIONS. Arrêter ou déconnecter l’équipement avant de démarrer ou d’arrêter le moteur. Ne pas laisser tourner le moteur trop lentement sous risque d’endommager le moteur électrique à cause d’une tension et d’une fréquence trop faibles. Ne pas brancher de moteur de 50 ou de 60 Hz à la prise de 100 Hz, s’il y a lieu. LE RAYONNEMENT HAUTE FRÉQUENCE (H.F.) risque de provoquer des interférences. LES ÉTINCELLES VOLANTES risquent de provoquer des blessures. L’EMPLOI EXCESSIF peut SURCHAUFFER L’ÉQUIPEMENT. Porter un écran facial pour protéger le visage et les yeux. Affuterr l’électrode au tungstène uniquement à la meuleuse dotée de protecteurs. Cette manoeuvre 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 substance inflammable. Établir la connexion avec la barrette de terre avant de manipuler des cartes ou des pièces. Utiliser des pochettes et des boîtes antistatiques pour stocker, déplacer ou expédier des cartes de circuits imprimes. UNE REMORQUE QUI BASCULE peut entraîner des blessures. Le rayonnement haute fréquence (H.F.) peut provoquer des interférences avec les équipements de radio–navigation et de communication, les services de sécurité et les ordinateurs. Demander seulement à des personnes qualifiées familiarisées avec des équipements électroniques de faire fonctionner l’installation. 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’appareil. 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 distance correcte et utiliser une terre et et un blindage pour réduire les interférences éventuelles. Laisser l’équipement refroidir ; respecter le facteur de marche nominal. Réduire le courant ou le facteur de marche avant de poursuivre le soudage. Ne pas obstruer les passages d’air du poste. LE SOUDAGE À L’ARC risque de provoquer des interférences. LES CHARGES ÉLECTROSTATIQUES peuvent endommager les circuits imprimés. Utiliser les supports de la remorque ou des blocs pour soutenir le poids. Installer convenablement le poste sur la remorque comme indiqué dans le manuel s’y rapportant. Utiliser seulement les pièces de rechange d’origine. Effectuer la maintenance du moteur et du compresseur (si applicable) suivant ce manuel et le manuel du moteur/compresseur (si applicable). 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 équipement 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 précédentes, il incombe à l’utilisateur de prendre des mesures supplémentaires telles que le déplacement du poste, l’utilisation de câbles blindés, l’utilisation de filtres de ligne ou la pose de protecteurs dans la zone de travail. 1-6.

Information sur les champs électromagnétiques Données sur le soudage électrique et les effets des champs magnétiques basse fréquence sur l’organisme En parcourant les câbles de soudage, le courant crée des champs électromagnétiques. Les effets potentiels de tels champs restent préoccupants. Cependant, après avoir examiné plus de 500 études qui ont été faites pendant une période de recherche de 17 ans, un comité de spécialistes du National Research Council a conclu : « L’accumulation de preuves n’a pas démontré que l’exposition aux champs magnétiques et aux champs électriques à haute fréquence constitue un risque pour la santé humaine ». Toutefois, les études et l’examen des preuves se poursuivent. En attendant les conclusions finales de la recherche, il serait souhaitable de réduire l’exposition aux champs électromagnétiques pendant le soudage ou le coupage. OM-4418 Page 8 Afin de réduire les champs électromagnétiques en milieu de travail, respecter les consignes suivantes : 1. Garder les câbles ensemble en les torsadant ou en les fixant avec du ruban adhésif. 2. Mettre tous les câbles du côté opposé à l’opérateur. 3. Ne pas s’enrouler les câbles autour du corps. 4. Garder le poste de soudage et les câbles le plus loin possible de soi. 5. Placer la pince de masse le plus près possible de la zone de soudage. Consignes relatives aux stimulateurs cardiaques : Les personnes qui portent un stimulateur cardiaque doivent avant tout consulter leur médecin. Si ce dernier les déclare aptes, il leur est recommandé de respecter les consignes ci-dessus. SECTION 2 – DEFINITIONS 2-1.

How Much Power Can Generator Supply? 1 Limit Load To 90% Of Generator Output Always start non-resistive (motor) loads in order from largest to smallest, and add resistive loads last. 2 1 2 5 Second Rule If motor does not start within 5 seconds, turn off power to prevent motor damage. Motor requires more power than generator can supply. Ref. ST-800 396-A / S-0625 OM-4418 Page 27 10-10. Typical Connections To Supply Standby Power Properly install and ground this equipment according to its Owner’s Manual and national, state, and local codes. 1 2 Utility Electrical Service 3 Transfer Switch 4 Fused Disconnect Switch (If Required) Welding Generator Output 5 Essential Loads Have only qualified persons perform these connections according to all applicable codes and safety practices. Switch transfers the electrical load from electric utility service to the generator. Transfer load back to electric utility when service is restored. Properly install and ground this equipment according to its Owner’s Manual and national, state, and local codes. Install correct switch (customer-supplied). Switch rating must be same as or greater than the branch overcurrent protection. Customer-supplied equipment is required if generator will supply standby power during emergencies or power outages. 1 Utility Electrical Service 2 Transfer Switch (Double-Throw) 3 Fused Disconnect Switch Install correct switch (customer-supplied) if required by electrical code. 4 Welding Generator Output Generator output voltage and wiring must be consistent with regular (utility) system voltage and wiring. Connect generator with temporary or permanent wiring suitable for the installation. Turn off or unplug all equipment connected to generator before starting or stopping engine. When starting or stopping, the engine has low speed which causes low voltage and frequency. 5 Essential Loads Generator output may not meet the electrical requirements of the premises. If generator does not produce enough output to meet all requirements, connect only essential loads (pumps, freezers, heaters, etc. – See Section 10-4). Notes Work like a Pro! Pros weld and cut safely. Read the safety rules at the beginning of this manual. OM-4418 Page 28 10-11.

Butt Joints 1 1 2 Tack Welds Prevent edges of joint from drawing together ahead of electrode by tack welding the materials in position before final weld. 2 Square Groove Weld Good for materials up to 3/16 in (5 mm) thick. 3 1/16 in (1.6 mm) 30° Single V-Groove Weld Good for materials 3/16 – 3/4 in (5-19 mm) thick. Cut bevel with oxyacetylene or plasma cutting equipment. Remove scale from material after cutting. A grinder can also be used to prepare bevels. 4 3 Create 30 degree angle of bevel on materials in V-groove welding. 4 Double V-Groove Weld Good for materials thicker than 3/16 in (5 mm). S-0662 11-11. Lap Joint 30° Or Less 30° Or Less 1 1 1 2 Move electrode in circular motion. 3 Single-Layer Fillet Weld 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 2 Electrode Single-Layer Fillet Weld Multi-Layer Fillet Weld S-0063 / S-0064 11-12. Tee Joint 1 2 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. 1 2 45° Or Less Electrode Fillet Weld For maximum strength weld both sides of upright section. 2 3 Multi-Layer Deposits Weld a second layer when a heavier fillet is needed. Use any of the weaving patterns shown in Section 11-9. Remove slag before making another weld pass. 1 3 S-0060 / S-0058-A / S-0061 OM-4418 Page 34 11-13. Weld Test 1 2 3 3 Strike weld joint in direction shown. A good weld bends over but does not break. 3 2 To 3 in (51-76 mm) 1/4 in (6.4 mm) Vise Weld Joint Hammer 2 To 3 in (51-76 mm) 2 2 1 1 S-0057-B 11-14. Troubleshooting – Porosity 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. 11-15. Troubleshooting – Excessive Spatter 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. OM-4418 Page 35 11-16. Troubleshooting – Incomplete Fusion 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. 11-17. Troubleshooting – Lack Of Penetration 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. 11-18. Troubleshooting – Excessive Penetration Excessive Penetration – weld metal melting through base metal and hanging underneath weld. Excessive Penetration Possible Causes Excessive heat input. Good Penetration Corrective Actions Select lower amperage. Use smaller electrode. Increase and/or maintain steady travel speed. OM-4418 Page 36 11-19. Troubleshooting – Burn-Through Burn-Through – weld metal melting completely through base metal resulting in holes where no metal remains. Possible Causes Excessive heat input. Corrective Actions Select lower amperage. Use smaller electrode. Increase and/or maintain steady travel speed. 11-20. Troubleshooting – Waviness Of Bead Waviness Of Bead – weld metal that is not parallel and does not cover joint formed by base metal. Possible Causes Unsteady hand. Corrective Actions Use two hands. Practice technique. 11-21. 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. Possible Causes Excessive heat input. Corrective Actions 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.
