SECTION 1 −WELDING HELMET SAFETY PRECAUTIONS −
READ BEFORE USING
helmet 2012−02
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 (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 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 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-248 440 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 air-
supplied respirator. The coatings and any metals containing these elements can give off toxic
fumes if welded.
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.

* 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.

Fixed Shade No. 10 Model
The fixed shade model has no but-
tons or controls. The lens turns on
(darkens) automatically when
welding begins and turns off when
welding stops.
Always make sure the lens is
fully charged before welding.
Place helmet in direct sunlight
for 20 minutes to charge the
lens assembly solar cell.

3-2. Auto On/Off Button And Low Battery Light (Variable Shade Helmets)
1 Auto On/Off Button
Press On/Off button to check if the
lens is working properly and to be-
gin lens shade, sensitivity, and
delay adjustments.
When the On/Off button is pressed,
the lens should darken and return to
the clear state. Do not use the hel-
met if the lens does not function as
described. (See Section 9, Trouble-
shooting.)
2 Grind / Low Battery Light
The Grind / Low Battery light blinks
when the lens is in the Grind mode.
Light stays on when 2−3 days of
battery life remain.
If battery power is low, replace with
CR2450 lithium batteries (2 re-
quired −Miller Part No. 217 043).
See Section 6.

3-3. Mode Control (Variable Shade Helmets)
1 Mode Control Button
Press Mode button to select the mode
appropriatefor the work activity:
Weld Mode −used for most welding
applications. In this mode the lens
turns on when it optically senses a
welding arc. Adjust shade, sensitivity,
and delay settings as needed.
Cut Mode −used for cutting applica-
tions. In this mode the lens turns on
when it optically senses a cutting arc.
Adjust shade, sensitivity, and delay
settings as needed.
Cut mode is not present on 62V or
52F helmets.
Grind Mode −used for metal grinding
applications.In this mode the shade is
fixed shade No. 3. No lens adjust-
ments are possible.

Adjustment Buttons
2 Mode Control Button
Use the LTR and DKR ad-
justment buttons to adjust
the lens shade in the dark-
ened state. Use the table in
Section 1-4 to select proper
shade control setting based
on your welding process.
The shade ranges for each
mode are as follows:
Weld −No. 8 −No. 13
Cut −No. 5 −No. 8
Grind −No. 3 only
Start at the highest setting
and adjust lighter to suit the
