. Means “Note”; not safety related.
1-2. Arc Welding Hazards
YThe 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 NO TAG. Read and follow all Safety Standards.
YOnly qualified persons should install, operate, maintain, and repair this unit.
YDuring 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.
DDo not touch live electrical parts.
DWear dry, hole-free insulating gloves and body protection.
DInsulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground.
DDo not use AC output in damp areas, if movement is confined, or if there is a danger of falling.
DUse AC output ONLY if required for the welding process.
DIf AC output is required, use remote output control if present on unit.
DDisconnect 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).
DProperly install and ground this equipment according to its Owner’s Manual and national, state, and local codes.
DAlways 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.
DWhen making input connections, attach proper grounding conductor first − double-check connections.
DFrequently inspect input power cord for damage or bare wiring − replace cord immediately if damaged − bare wiring can kill.
DTurn off all equipment when not in use.
DDo not use worn, damaged, undersized, or poorly spliced cables.
DDo not drape cables over your body.
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.
DIf earth grounding of the workpiece is required, ground it directly with a separate cable.
DDo not touch electrode if you are in contact with the work, ground, or another electrode from a different machine.
DUse only well-maintained equipment. Repair or replace damaged parts at once. Maintain unit according to manual.
DWear a safety harness if working above floor level.
DKeep all panels and covers securely in place.
DClamp work cable with good metal-to-metal contact to workpiece or worktable as near the weld as practical.
DInsulate work clamp when not connected to workpiece to prevent contact with any metal object.
DDo not connect more than one electrode or work cable to any single weld output terminal.
SIGNIFICANT DC VOLTAGE exists after removal of input power on inverters.
DTurn Off inverter, disconnect input power, 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.
DKeep your head out of the fumes. Do not breathe the fumes.
DIf inside, ventilate the area and/or use exhaust at the arc to remove welding fumes and gases.
DIf ventilation is poor, use an approved air-supplied respirator.
DRead the Material Safety Data Sheets (MSDSs) and the manufacturer’s instructions for metals, consumables, coatings, cleaners, and degreasers.
DWork 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.
DDo 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.
DDo 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-181 712 Page 1
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.
DWear a welding helmet fitted with a proper shade of filter to protect your face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards).
DWear approved safety glasses with side shields under your helmet.
DUse protective screens or barriers to protect others from flash and glare; warn others not to watch the arc.
DWear protective clothing made from durable, flame-resistant material (leather and wool) and foot protection.
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.
DProtect yourself and others from flying sparks and hot metal.
DDo not weld where flying sparks can strike flammable material.
DRemove all flammables within 35 ft (10.7 m) of the welding arc. If this is not possible, tightly cover them with approved covers.
DBe alert that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.
DWatch for fire, and keep a fire extinguisher nearby.
DBe aware that welding on a ceiling, floor, bulkhead, or partition can cause fire on the hidden side.
DDo not weld on closed containers such as tanks, drums, or pipes, unless they are properly prepared according to AWS F4.1 (see Safety Standards).
DConnect 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.
DDo not use welder to thaw frozen pipes.
DRemove stick electrode from holder or cut off welding wire at contact tip when not in use.
DWear oil-free protective garments such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.
DRemove any combustibles, such as a butane lighter or matches, from your person before doing any welding.
FLYING METAL can injure eyes.
DWelding, chipping, wire brushing, and grinding cause sparks and flying metal. As welds cool, they can throw off slag.
DWear approved safety glasses with side shields even under your welding helmet.
OM-181 712 Page 2
BUILDUP OF GAS can injure or kill.
D Shut off shielding gas supply when not in use.
D Always ventilate confined spaces or use approved air-supplied respirator.
HOT PARTS can cause severe burns.
DDo not touch hot parts bare handed.
DAllow cooling period before working on gun or
torch.

Wearers should consult their doctor before |
|
going near arc welding, gouging, or spot |
|
welding operations. |
NOISE can damage hearing.
Noise from some processes or equipment can damage hearing.
DWear approved ear protection if noise level is high.
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.
DProtect compressed gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs.
DInstall cylinders in an upright position by securing to a stationary support or cylinder rack to prevent falling or tipping.
DKeep cylinders away from any welding or other electrical circuits.
DNever drape a welding torch over a gas cylinder.
DNever allow a welding electrode to touch any cylinder.
DNever weld on a pressurized cylinder − explosion will result.
DUse only correct shielding gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them and associated parts in good condition.
DTurn face away from valve outlet when opening cylinder valve.
DKeep protective cap in place over valve except when cylinder is in use or connected for use.
DRead and follow instructions on compressed gas cylinders, associated equipment, and CGA publication P-1 listed in Safety Standards.
