Arc Welding HazardsThe symbols shown below are used throughout this manualto call attention to and identify possible hazards. When yousee the symbol, watch out, and follow the related instructionsto avoid the hazard. The safety information given below isonly a summary of the more complete safety informationfound in the Safety Standards listed in Section 1-5. Read andfollow all Safety Standards.Only qualified persons should install, operate, maintain, andrepair this unit.During operation, keep everybody, especially children, away.ELECTRIC SHOCK can kill.Touching live electrical parts can cause fatal shocksor severe burns. The electrode and work circuit iselectrically live whenever the output is on. The inputpower circuit and machine internal circuits are alsolive when power is on. In semiautomatic or automaticwire welding, the wire, wire reel, drive roll housing,and all metal parts touching the welding wire areelectrically live. Incorrectly installed or improperlygrounded equipment is a hazard.D Do not touch live electrical parts.D Wear dry, hole-free insulating gloves and body protection.D Insulate yourself from work and ground using dry insulating matsor covers big enough to prevent any physical contact with the workor ground.D Do not use AC output in damp areas, if movement is confined, or ifthere is a danger of falling.D Use AC output ONLY if required for the welding process.D If AC output is required, use remote output control if present onunit.D Additional safety precautions are required when any of the following electrically hazardous conditions are present: in damplocations or while wearing wet clothing; on metal structures suchas floors, gratings, or scaffolds; when in cramped positions suchas sitting, kneeling, or lying; or when there is a high risk of unavoidable or accidental contact with the workpiece or ground. For theseconditions, use the following equipment in order presented: 1) asemiautomatic 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 welderis recommended. And, do not work alone!D Disconnect input power or stop engine before installing orservicing this equipment. Lockout/tagout input power according toOSHA 29 CFR 1910.147 (see Safety Standards).D Properly install, ground, and operate this equipment according toits Owner’s Manual and national, state, and local codes.D Always verify the supply ground check and be sure that inputpower cord ground wire is properly connected to ground terminal indisconnect box or that cord plug is connected to a properlygrounded receptacle outlet.D When making input connections, attach proper grounding conductor first double-check connections.D Keep cords dry, free of oil and grease, and protected from hot metaland sparks.D Frequently inspect input power cord and ground conductor fordamage or bare wiring – replace immediately if damaged – barewiring can kill.D Turn off all equipment when not in use.D Do not use worn, damaged, undersized, or repaired cables.D Do not drape cables over your body.D If earth grounding of the workpiece is required, ground it directlywith a separate cable.D Do not touch electrode if you are in contact with the work, ground,or another electrode from a different machine.D Do not touch electrode holders connected to two welding machines at the same time since double open-circuit voltage will bepresent.D Use only well-maintained equipment. Repair or replace damagedparts at once. Maintain unit according to manual.D Wear a safety harness if working above floor level.D Keep all panels and covers securely in place.D Clamp work cable with good metal-to-metal contact to workpieceor worktable as near the weld as practical.D Insulate work clamp when not connected to workpiece to preventcontact with any metal object.D Do not connect more than one electrode or work cable to anysingle weld output terminal. Disconnect cable for process not inuse.D Use GFCI protection when operating auxiliary equipment in dampor wet locations.SIGNIFICANT DC VOLTAGE exists in inverter welding power sources AFTER removal of input power.D Turn Off inverter, disconnect input power, and discharge inputcapacitors according to instructions in Maintenance Sectionbefore touching any parts.HOT PARTS can burn.D Do not touch hot parts bare handed.D Allow cooling period before working onequipment.D To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns.OM-220388 Page 1

FUMES AND GASES can be hazardous.Welding produces fumes and gases. Breathingthese fumes and gases can be hazardous to yourhealth.D Keep your head out of the fumes. Do not breathe the fumes.D If inside, ventilate the area and/or use local forced ventilation at thearc to remove welding fumes and gases. The recommended wayto determine adequate ventilation is to sample for the compositionand quantity of fumes and gases to which personnel are exposed.D If ventilation is poor, wear an approved air-supplied respirator.D Read and understand the Safety Data Sheets (SDSs) and themanufacturer’s instructions for adhesives, coatings, cleaners,consumables, coolants, degreasers, fluxes, and metals.D Work in a confined space only if it is well ventilated, or whilewearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air andlower the oxygen level causing injury or death. Be sure the breathing air is safe.D Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to formhighly toxic and irritating gases.D Do not weld on coated metals, such as galvanized, lead, orcadmium plated steel, unless the coating is removed from the weldarea, the area is well ventilated, and while wearing an air-suppliedrespirator. The coatings and any metals containing these elementscan give off toxic fumes if welded.ARC RAYS can burn eyes and skin.Arc rays from the welding process produce intensevisible and invisible (ultraviolet and infrared) raysthat can burn eyes and skin. Sparks fly off from theweld.D Wear an approved welding helmet fitted with a proper shade offilter lenses to protect your face and eyes from arc rays andsparks when welding or watching (see ANSI Z49.1 and Z87.1listed in Safety Standards).D Wear approved safety glasses with side shields under yourhelmet.D Use protective screens or barriers to protect others from flash,glare and sparks; warn others not to watch the arc.D Wear body protection made from durable, flame resistant material (leather, heavy cotton, wool). Body protection includesoil-free clothing such as leather gloves, heavy shirt, cufflesstrousers, 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. Sparkscan fly off from the welding arc. The flying sparks, hotworkpiece, and hot equipment can cause fires andburns. Accidental contact of electrode to metal objects can causesparks, explosion, overheating, or fire. Check and be sure the area issafe before doing any welding.D Remove all flammables within 35 ft (10.7 m) of the welding arc. Ifthis is not possible, tightly cover them with approved covers.D Do not weld where flying sparks can strike flammable material.D Protect yourself and others from flying sparks and hot metal.D Be alert that welding sparks and hot materials from welding caneasily go through small cracks and openings to adjacent areas.D Watch for fire, and keep a fire extinguisher nearby.D Be aware that welding on a ceiling, floor, bulkhead, or partition cancause fire on the hidden side.D Do not weld on containers that have held combustibles, or onclosed containers such as tanks, drums, or pipes unless they areproperly prepared according to AWS F4.1 and AWS A6.0 (seeSafety Standards).D Do not weld where the atmosphere can contain flammable dust,gas, or liquid vapors (such as gasoline).D Connect work cable to the work as close to the welding area aspractical to prevent welding current from traveling long, possiblyunknown paths and causing electric shock, sparks, and firehazards.D Do not use welder to thaw frozen pipes.OM-220388 Page 2D Remove stick electrode from holder or cut off welding wire atcontact tip when not in use.D Wear body protection made from durable, flame resistant material(leather, heavy cotton, wool).
