SECTION 1 −WELDING HELMET AND WELDING GOGGLE
SAFETY PRECAUTIONS −READ BEFORE USING
Weld Gog. 2016-11
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 welding helmet or welding goggles 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. Safety glasses are not
required with auto−darkening welding goggles; the welding goggles meet the eye protection
requirements of ANSI Z87.1.
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, 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.
•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.

OM-280995 Page 2
WELDING HELMETS AND WELDING GOGGLES 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
the welding helmet. Safety glasses are not required with auto−darkening welding goggles; the
welding goggles meet the eye protection requirements of ANSI Z87.1.
Do not use the welding helmet or welding goggles while working with or around explosives or
corrosive liquids.
Do not weld in the overhead position while using the welding helmet or welding goggles.
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.
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 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.
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-280995 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 known to the state of California to cause cancer, birth
defects, or other reproductive harm. Wash hands after use.

light levels in various welding pro-
cesses. Use a mid-range or
30−50% sensitivity setting for
most applications.It may be nec-
essary to adjust weld-mask sensi-
tivity to accommodate different
lighting conditions or if lens is
flashing on and off.
Choose from five Sensitivity levels
(low to high). Sensitivity level is in-
dicated by the center number on
the LCD display.

SECTION 9 −MAINTENANCE
NOTICE −Never use solvents or abrasive cleaning detergents.
NOTICE −Do not immerse the lens assembly in water.
The weld-mask requires little maintenance. However, for best performance clean after each use. Us-
ing 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-280995 Page 13
SECTION 10 −TROUBLESHOOTING
Trouble Remedy
Not switching – auto-lens
stays light and does not
darken when welding or
cutting.
Stop welding or cutting immediately: Make sure the lens is turned
On.
If power is On, check the shade settings. Also review sensitivity
recommendations and adjust sensitivity if possible.
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 arc is
extinguished, or the auto-
lens stays dark when no
arc is present.
Reduce Sensitivity setting (see Section 3-6). In extreme light con-
ditions, it may be necessary to reduce the surrounding light levels.
If the lens remains dark, press the Auto On/Off button to return
lens to the clear state.
Move weld-mask away from light source.
Inconsistent or lighter
auto-lens shading in the
dark-state, noticeable on
the outside edges and cor-
ners.
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.
Sections of the auto-lens
are not going dark, distinct
lines separate the light and
dark areas.
Stop welding or cutting immediately: The auto-lens may be
cracked which can be caused by the impact of dropping the
weld-mask.
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
or cutting 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.
Move closer to arc.
