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 welding power source Owner's Manual. 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.
D Always wear dry insulating gloves.
D Insulate yourself from work and ground.
D Do not touch live electrode or electrical parts.
D Replace worn, damaged, or cracked guns or cables.
D Turn off welding power source before changing contact tip or gun
parts.
D Keep all covers and handle securely in place.
FUMES AND GASES can be hazardous.
D Keep your head out of the fumes.
D Ventilate area, or use breathing device. The
recommended way to determine adequate
ventilation is to sample for the composition and quantity of fumes
and gases to which personnel are exposed.
D Read and understand the Safety Data Sheets (SDSs) and the
manufacturer's instructions for adhesives, coatings, cleaners,
consumables, coolants, degreasers, fluxes, and metals.
WELDING can cause fire or explosion.
D Do not weld near flammable material.
D Do not weld on containers that have held com-
bustibles, or on closed containers such as
tanks, drums, or pipes unless they are properly prepared ac-
cording to AWS F4.1 and AWS A6.0 (see Safety Standards).
D Watch for fire; keep extinguisher nearby.

Indicates special instructions.
This group of symbols means Warning! Watch Out! ELECTRIC
SHOCK, MOVING PARTS, and HOT PARTS hazards. Consult sym-
bols and related instructions below for necessary actions to avoid the
hazards.
BUILDUP OF GAS can injure or kill.
D Shut off compressed gas supply when not in
use.
D Always ventilate confined spaces or use ap-
proved air-supplied respirator.
MOVING PARTS can injure.
D Keep away from moving parts.
D Keep away from pinch points such as drive
rolls.
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.
D 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).
D Wear approved safety glasses with side shields under your
helmet.
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 includes oil-free
clothing such as leather gloves, heavy shirt, cuffless trousers, high
shoes, and a cap.
HOT PARTS can burn.
D Allow gun to cool before touching.
D Do not touch hot metal.
D Protect hot metal from contact by others.
