Out! ELECTRIC SHOCK, MOVING PARTS,
and HOT PARTS hazards. Consult symbols
and related instructions below for necessary
actions to avoid the hazards.

 Indicates special instructions.

DANGER! − Indicates a hazardous
situation which, if not avoided, will
result in death or serious injury. The
possible hazards are shown in the
adjoining symbols or explained in
the text.

Indicates a hazardous situation
which, if not avoided, could result in
death or serious injury. The possible
hazards are shown in the adjoining
symbols or explained in the text.

NOTICE − Indicates statements not related to

personal injury.

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-246 377 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 air­supplied respirator. The coatings and any metals containing these elements can give off toxic
fumes if welded.

 Be sure Positive (+) side of

the battery faces up (to­ward inside of helmet).

Reinstall the battery trays. To
test battery, press the Reset
button. The lens should flash
dark twice. Reinstall the lens
assembly.

 Left and right battery trays

SECTION 10 − MAINTENANCE

NOTICE − Never use solvents or abrasive cleaning detergents.
NOTICE − Do not immerse the lens assembly in water.

The helmet requires little maintenance. However, for best performance clean
after each use. Using a soft cloth dampened with a mild soap and water solution,
wipe the cover lenses clean. Allow to air dry. Occasionally, the filter lens and
sensors should be cleaned by gently wiping with a soft, dry cloth.

OM-246 377 Page 20

SECTION 11 − TROUBLESHOOTING

Trouble Remedy

Auto lens not ON – auto­lens will not darken mo­mentarily when the Reset
button is pressed.

Check batteries and verify they are in good condition and installed
properly. Also, check battery surfaces and contacts and clean if
necessary. Check battery for proper contact and gently adjust
contact points if necessary. This is particularly important if the
helmet has been dropped. Verify left and right battery trays are
installed on the correct sides.

Not switching – auto-lens
stays light and will not
darken when welding.

Stop welding immediately: Press the Reset button if lens is Auto­On type. If lens if Manual-On type, make sure the lens is turned
On. If power is on, review the sensitivity recommendations and
adjust sensitivity. Clean lens cover and sensors of any obstruc­tions. Make sure the sensors are facing the arc; angles of 45 or
more may not allow the arc light to reach the sensors.

Not Switching – auto-lens
stays dark after the weld
arc is extinguished, or the
auto-lens stays dark when
no arc is present.

Fine-tune the sensitivity setting by making small adjustments to
the control by turning it toward the “min” setting. In extreme light
conditions, it may be necessary to reduce the surrounding light
levels.

Sections of the auto-lens
are not going dark, distinct
lines separate the light and
dark areas.

Stop welding immediately: The auto-lens may be cracked which
can be caused by the impact of dropping the helmet. Weld spatter
on the auto lens may also cause cracking. (The lens may need to
be replaced; most cracked lenses are not covered by warranty).

Switching or Flickering –
the auto-lens darkens then
lightens while the welding
arc is present.

Review the sensitivity setting recommendations and increase the
sensitivity if possible. Be sure the arc sensors are not being
blocked from direct access to the arc light. Check the lens cover
for dirt and spatter that may be blocking the arc sensors. Increas­ing Lens Delay 0.1 − 0.3 second may also reduce switching.

Inconsistent or lighter
auto-lens shading in the
dark-state, noticeable on
the outside edges and cor­ners.

Referred to as an angle of view effect, auto-darkening lenses
have an optimum viewing angle. The optimum viewing angle is
perpendicular or 90 to the surface of the auto-lens. When that
angle of view varies in the dark-state, welders may notice slightly
lighter areas at the outside edges and the corners of the lens. This
is normal and does not represent any health or safety hazard.
This effect may also be more noticeable in applications where
magnifying lenses are used.
