1-2. Arc Welding Hazards

Only qualified persons should install, operate, maintain, and repair this unit.

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.

Wear a welding helmet fitted with a proper shade of filter to protect your face and eyes when

welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards). Refer to Shade

and Sensitivity charts.

Wear approved safety glasses with side shields under your helmet.

Use protective screens or barriers to protect others from flash, glare, and sparks; warn

others not to watch the arc.

Wear protective clothing made from durable, flame-resistant material (leather, heavy cotton,

and wool) and foot protection.

•Before welding, adjust the auto-darkening lens sensitivity setting to meet the application.

•Stop welding immediately if the auto-darkening lens does not darken when the arc is struck.

See the Owner’s Manual for more information.

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.

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.

Do not weld in the overhead position while using this helmet.

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

lenses or auto-lenses.

WELDING HELMETS do not provide unlimited eye, ear and

face protection.

OM-252 052 Page 2

Noise from some processes or equipment can damage hearing.

 Wear approved ear protection if noise level is high.

NOISE can damage hearing.

READ INSTRUCTIONS.

Read and follow all labels and the Owner’s Manual carefully before installing,

operating,or servicing unit. Read the safety information at the beginning of

the manual and in each section.

Use only genuine replacement parts from the manufacturer.

Perform 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.

If inside, ventilate the area and/or use local forced ventilation at the arc to remove welding

fumes and gases.

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

Read and understand the Material Safety Data Sheets (MSDSs) and the manufacturer’s

instructions for metals, consumables, coatings, cleaners, and degreasers.

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.

1-3. Proposition 65 Warnings

Welding or cutting equipment produces fumes or gases which contain chemicals known

to the State of California to cause birth defects and, in some cases, cancer. (California

Health & Safety Code Section 25249.5 et seq.)

This product contains chemicals, including lead, known to the state of California to cause

cancer, birth defects, or other reproductive harm. Wash hands after use.

SECTION 3 −OPERATING INSTRUCTIONS

3-1. Helmet Controls

Two different lens assemblies are

shown. Refer to the illustration

that matches the lens on your

helmet.

The auto-darkening lens turns

on (darkens) automatically

when welding begins and turns

off when welding stops.

1 Reset Button

Press Reset button to check if the

lens is working properly.

When the Reset button is pressed,

the lens should darken twice and re-

turn to the clear state. Do not use

the helmet if the lens does not func-

tion as described. (See Section 9,

Troubleshooting.)

The low battery indicator lights

when 2−3 days of battery life re-

main.

If battery power is low, replace with

AAA Alkaline Batteries only (see

Section 6).

3-3. Lens Delay Control

1 Lens Delay Control

The lens delay control is used to

adjust the time for the lens to switch

to the clear state after welding.

The delay is particularly useful in

eliminating bright after-rays pres-

ent in higher amperage applica-

tions where the molten puddle re-

mains bright momentarily after

welding. Adjusts from slow to fast.
