Protect yourself and others from injury — read, follow, and save these important safety
precautions and operating instructions.
1-1. Symbol Usage
This group of symbols means Warning! Watch
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 (ultravio-
let 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 Lens
Shade Selection table in Section 1-4.
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 body protection made from durable, flameresistant material (leather, heavy cotton,
wool). Body protection includes oil-free clothing such as leather gloves, heavy shirt, cuffless
trousers, high shoes, and a cap.
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 Owners Manual for more information.
ARC RAYS can burn eyes and skin.
OM-269 681 Page 2
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 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.
NOISE can damage hearing.
Noise from some processes or equipment can damage hearing.
Wear approved ear protection if noise level is high.
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 maintenance and service according to the Owners 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. The recommended way to determine adequate ventilation is to sample for
the composition 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.
OM-269 681 Page 3
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.

Auto lens not On – auto-
lens will not darken.
Check batteries and verify they are in good condition and installed
properly.
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.
Not switching – auto-lens
stays light and will not
darken when welding.
Stop welding immediately: Press the Auto On/Off button.
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 in small increments. 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.
