SECTION 1 – SAFETY PRECAUTIONS –
READ BEFORE USING
Protect yourself and others from injury—read, follow, and save these important safety
precautions and operating instructions.
1-1. Symbol Usage
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 ex-
plained in the text.
Indicates a hazardous situation which, if not avoided, could result in death or seri-
ous injury. The possible hazards are shown in the adjoining symbols or explained in
the text.
NOTICE – Indicates statements not related to personal injury.
F
Indicates special instructions.
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 these hazards.
1-2. Arc Welding Hazards
The symbols shown below are used throughout this manual to call attention to and
identify possible hazards. When you see the symbol, watch out, and follow the related
instructions to avoid the hazard. The safety information given below is only a sum-
mary of the more complete safety information found in the Principal Safety Standards
listed in Section 1-5. Read and follow all Safety Standards.
Only qualified persons should install, operate, maintain, and repair this equipment. A
qualified person is defined as one who, by possession of a recognized degree, certifi-
cate, or professional standing, or who by extensive knowledge, training and experi-
ence, has successfully demonstrated the ability to solve or resolve problems relating
to the subject matter, the work, or the project and has received safety training to rec-
ognize and avoid the hazards involved.
During operation, keep everybody, especially children, away.
ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense visible and invisible (ultra-
violet and infrared) rays that can burn eyes and skin. Sparks fly off from the
weld.
lWear 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 Principal Safety
Standards). Refer to Lens Shade Selection table in Section 1-4.
lWear approved safety glasses with side shields under your helmet.
lUse protective screens or barriers to protect others from flash, glare, and sparks; warn others
not to watch the arc.
lWear 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.

OM-269681 Page 2
lBefore welding, adjust the auto-darkening lens sensitivity setting to meet the application.
lStop welding immediately if the auto-darkening lens does not darken when the arc is struck.
NOISE can damage hearing.
Noise from some processes or equipment can damage hearing.
lWear approved ear protection if noise level is high.
WELDING HELMETS do not provide unlimited eye, ear,
and face protection.
Arc rays from the welding process produce intense visible and invisible (ultra-
violet and infrared) rays that can burn eyes and skin. Sparks fly off from the
weld.
lUse helmet for welding/cutting applications only. Do not use helmet for laser welding/cutting.
lUse impact resistant safety spectacles or goggles and ear protection at all times when using
this welding helmet.
lDo not use this helmet while working with or around explosives or corrosive liquids.
lThis 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.
lInspect the auto-lens frequently. Immediately replace any scratched, cracked, or pitted cover
lenses or auto-lenses.
lLens and retention components must be installed as instructed in this manual to ensure com-
pliance with ANSI Z87.1 protection standards.
lThis helmet provides protection from projectiles associated with grinding, chipping, and re-
lated activities; it is not a hard hat and does not provide protection from falling objects.
READ INSTRUCTIONS.
lRead 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.
lUse only genuine replacement parts from the manufacturer.
lPerform 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.
lKeep your head out of the fumes. Do not breathe the fumes.
lVentilate 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
composition and quantity of fumes and gases to which personnel are exposed.
lIf ventilation is poor, wear an approved air-supplied respirator.
lRead and understand the Safety Data Sheets (SDSs) and the manufacturer’s instructions for
adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.
lWork 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.

OM-269681 Page 3
lDo 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.
lDo 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.
