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-

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.

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.
