1. SAFETY INSTRUCTIONS AND

WARNINGS

1.1 ARC WELDING HAZARDS

WARNING

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 semi-automatic 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.

1. Do not touch live electrical parts.

2. Wear dry, hole-free insulating gloves and body

protection.

3. Insulate yourself from work and ground using dry

insulating mats or covers.

4. Disconnect input power or stop engine before

installing or servicing this equipment. Lock input

power disconnect switch open, or remove line fuses

so power cannot be turned on accidentally.

5. Properly install and ground this equipment according

to its Owner’s Manual and national, state, and local

codes.

6. Turn OFF all equipment when not in use. Disconnect

power to equipment if it will be left unattended or

out of service.

7. Use fully insulated electrode holders. Never dip

holder in water to cool it or lay it down on the

ground or the work surface. Do not touch holders

connected to two welding machines at the same

time or touch other people with the holder or

electrode.

8. Do not use worn, damaged, undersized, or poorly

spliced cables.

9. Do not wrap cables around your body.

10. Ground the workpiece to a good electrical (earth)

ground.

11. Do not touch electrode while in contact with the

work (ground) circuit.

12. Use only well-maintained equipment. Repair or

replace damaged parts at once.

13. In conﬁned spaces or damp locations, do not use a

welder with AC output unless it is equipped with a

voltage reducer. Use equipment with DC output

14. Wear a safety harness to prevent falling if working

above ﬂoor level.

15. Keep all panels and covers securely in place.

WARNING

ARC RAYS can burn eyes and skin;

NOISE can damage hearing.

Arc rays from the welding process produce intense heat

and strong ultraviolet rays that can burn eyes and skin.

Noise from some processes can damage hearing.

1. Wear a welding helmet ﬁtted with a proper shade of

ﬁlter to protect your face and eyes when welding or

watching.

2. Wear approved safety glasses. Side shields

recommended.

3. Use protective screens or barriers to protect others

from ﬂash and glare; warn others not to watch the

arc.

4. Wear protective clothing made from durable,

ﬂame-resistant material (wool and leather) and foot

protection.

5. Use approved ear plugs or ear muffs if noise level is

high.

6. Never wear contact lenses while welding.

WARNING

FUMES AND GASES

can be hazardous to your health.

Welding produces fumes and gases.

Breathing these fumes and gases can be hazardous to

your health.

1. Keep your head out of the fumes. Do not breathe

the fumes.

2. If inside, ventilate the area and/or use exhaust at

the arc to remove welding fumes and gases.

3. If ventilation is poor, use an approved air-supplied

respirator.

4. Read the Material Safety Data Sheets (MSDSs)

and the manufacturer’s instruction for metals,

consumables, coatings, and cleaners.

5. Work in a conﬁned space only if it is well ventilated,

or while wearing an air-supplied respirator. Shielding

gases used for welding can displace air causing

injury or death. Be sure the breathing air is safe.

6. Do not weld in locations near degreasing, cleaning,

or spraying operations. The heat and rays of the

arc can react with vapours to form highly toxic and

irritating gases.

7. 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

airsupplied respirator. The coatings and any metals

containing these elements can give off toxic fumes if

welded.

WARNING

Welding can cause FIRE or

EXPLOSION.

Sparks and spatter ﬂy off from the

welding arc

The ﬂying sparks and hot metal, weld spatter, hot

workpiece, and hot equipment can cause ﬁres and

burns.

Accidental contact of electrode or welding wire to metal

objects can cause sparks, overheating, or ﬁre

1. Protect yourself and others from ﬂying sparks and

hot metal.

2 Do not weld where ﬂying sparks can strike

ﬂammable material.

3. Remove all ﬂammables within 35 ft (11 m) of the
