SECTION 1 −SAFETY PRECAUTIONS −
READ BEFORE USING
Protect yourself and others from injury — read and follow these precautions.
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.
NOTICE −Indicates statements not related to
personal injury.
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.
1-2. Hazards
ARC RAYS can burn eyes and skin.
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.
DWear 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 Shade and Sensitivity charts in Sections 3-4
and 3-5.
DWear approved safety glasses with side shields under your helmet.
DUse protective screens or barriers to protect others from flash and glare;
warn others not to watch the arc.
DWear protective clothing made from durable, flame-resistant material
(leather and wool) and foot protection.
WELDING HELMETS do not provide unlimited eye, ear and
face protection.
DUse impact resistant safety spectacles or goggles and ear protection at all
times when using this welding helmet.
DDo not use this helmet while working with or around explosives or
corrosive liquids.
DDo not weld in the overhead position while using this helmet.
DInspect 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.
DWear approved ear protection if noise level is high.

3-2. On-Off Button And Low Battery Indicator
1 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 Low Battery Indicator
The message “Low Battery” ap-
pears on the display screen when
2−3 days of battery life remains.
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
1 Mode Control Button
Press button to select the mode ap-
propriate for 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.
Cutting Mode −used for cutting ap-
plications. In this mode the lens turns
on when it optically senses a cutting
arc. Adjust shade, sensitivity, and
delay settings as needed.
Grind Mode −used for metal grinding
applications. In this mode the shade is
fixed shade No. 3. No lens adjust-
ments are possible.
X Mode −used for outdoor or low cur-
rent welding applications. In this mode
the lens turns on when it senses weld
current. Adjust shade, sensitivity, and
delay settings as needed.
.Nearby welding may affect hel-
met operation when lens is in X
Mode. Stay at least 12 ft (3.7 m)
away from other welding activity.

Use the shade control Down and
Up buttons to select the lens
shade in the darkened state. The
shade ranges for each mode are
as follows:
Weld −No. 8 −No. 13
Cutting −No. 5 −No. 8
Grind −No. 3 only
X Mode −No. 8 −No. 13

3-5. Sensitivity Control
1 Sensitivity Control Buttons
Use Sensitivity Control Low and Hi buttons
to make the lens more responsive to differ-
ent light levels in various welding pro-
cesses. Use a sensitivity setting of 5 for
most applications.
The sensitivity ranges for each mode are as
follows:
Weld, Cutting, X Modes −0 −10
Grind Mode −No sensitivity adjustment
It may be necessary to adjust helmet sensi-
tivity to accommodate different lighting con-
ditions or if lens is flashing On and Off. Ad-
just helmet sensitivity as follows:
.Adjust helmet sensitivity in lighting con-
ditions helmet will be used in.
SPress Sensitivity Low button to lower
setting to 0.
SFace the helmet in the direction of use,
exposing it to the surrounding light con-
ditions.
SPress Sensitivity Hi button repeatedly
until the lens darkens, then press Low
button until lens clears. Helmet is ready
for use. Slight readjustment may be
necessary for certain applications or if
lens is flashing on and off.

3-6. Lens Delay Control
1 Lens Delay Control
Use the Lens Delay Control Fast
and Slow buttons to adjust the time
for the lens to switch to the clear
state after welding or cutting.
The delay is particularly useful in
eliminating bright after-rays pres-
ent in higher amperage applica-
tions where the molten puddle re-
mains bright momentarily after
welding. Use the Lens Delay Con-
trol buttons to adjust delay from 0 to
10 (0.1 to 1.0 second).
.There is no lens delay adjust-
ment in the Grind mode.
