bols 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 welding power source Owner’s Manual. Read

and follow all Safety Standards.

Only qualified persons should install, operate, maintain, and

repair this equipment. A qualified person is defined as one

who, by possession of a recognized degree, certificate, or

professional standing, or who by extensive knowledge, train-

ing and experience, has successfully demonstrated ability to

solve or resolve problems relating to the subject matter, the

work, or the project and has received safety training to recog-

nize and avoid the hazards involved.

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.

MOVING PARTS can injure.

D

Keep away from moving parts.

D

Keep away from pinch points such as drive

rolls.

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.

D

Read and understand the Safety Data Sheets (SDSs) and the

manufacturer’s instructions for adhesives, coatings, cleaners,

consumables, coolants, degreasers, fluxes, and metals.

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.

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.

ARC RAYS can burn eyes and skin.

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.
