SECTION 1 −WELDING HELMET SAFETY PRECAUTIONS −
READ BEFORE USING
helmet 2018-08
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 equipment. A
qualified person is defined as one who, by possession of a recognized degree, certificate,
or professional standing, or who by extensive knowledge, training and experience, has
successfully demonstrated ability to solve or resolve problems relating to the subject
matter, the work, or the project and has received safety training to recognize and avoid
the hazards involved.
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, 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.
ARC RAYS can burn eyes and skin.
NOISE can damage hearing.
Noise from some processes or equipment can damage hearing.
 Wear approved ear protection if noise level is high.

OM-256476 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 helmet for welding/cutting applications only. Do not use helmet for laser welding/cutting.
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.
This 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.
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.
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.
Ventilate 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 com-
position 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.

* Start with a shade that is too dark to see the weld zone. Then, go to a lighter shade which gives a
sufficient view of the weld zone without going below the minimum.
