WELDING HELMETS do not provide unlimited eye, ear, and

face protection.

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.

Use helmet for welding/cutting applications only. Do not use helmet for laser welding/cutting.

Use impact resistant safety spectacles or goggles and ear protection at all times when using

this welding helmet.

Do not use this helmet while working with or around explosives or corrosive liquids.

This helmet is not rated for overhead welding. Do not weld in the direct overhead position

while using this helmet unless additional precautions are taken to protect yourself from arc

rays, spatter, and other hazards.

Inspect the auto-lens frequently. Immediately replace any scratched, cracked, or pitted cover

lenses or auto-lenses.

Lens and retention components must be installed as instructed in this manual to ensure

compliance with ANSI Z87.1 protection standards.

READ INSTRUCTIONS.

Read and follow all labels and the Owner’s Manual carefully before in-

stalling, operating, or servicing unit. Read the safety information at the be-

ginning of the manual and in each section.

Use only genuine replacement parts from the manufacturer.

Perform installation, maintenance, and service according to the Owner’s Manuals, industry

standards, and national, state, and local codes.

FUMES AND GASES can be hazardous.

Welding produces fumes and gases. Breathing these fumes and gases can be

hazardous to your health.

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

Ventilate the work area and/or use local forced ventilation at the arc to remove welding fumes

and gases. The recommended way to determine adequate ventilation is to sample for the com-

position and quantity of fumes and gases to which personnel are exposed.

If ventilation is poor, wear an approved air-supplied respirator.

Read and understand the Safety Data Sheets (SDSs) and the manufacturer’s instructions for

adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.

Work 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.

Do 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.

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 while wearing an air-

supplied respirator. The coatings and any metals containing these elements can give off toxic

fumes if welded.
