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.
D 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
D Wear approved safety glasses with side shields under your helmet.
D Use protective screens or barriers to protect others from flash and glare;
warn others not to watch the arc.
D Wear 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.
D Use impact resistant safety spectacles or goggles and ear protection at all
times when using this welding helmet.
D Do not use this helmet while working with or around explosives or
corrosive liquids.
D Do not weld in the overhead position while using this helmet.
D Inspect 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.
D Wear approved ear protection if noise level is high.

1
Mode Control Button
Press button to select the mode ap-
propriatefor 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.

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:
1
. Adjust helmet sensitivity in lighting con-
ditions helmet will be used in.
S
S
Press Sensitivity Low button to lower
setting to 0.
Face the helmet in the direction of use,
exposing it to the surrounding light con-
ditions.
S
Press 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.

Four pins on the right side of the
headband top provide adjustment
for the forward tilt of the helmet. To
adjust, loosen the right outside ten-
sion adjustment knob then lift on the
control arm tab and move it to the de-
sired position. Retighten tension ad-
justment knob.

SECTION 8 − MAINTENANCE
NOTICE − Never use solvents or abrasive cleaning detergents.
NOTICE − Do not immerse the lens assembly in water.
The helmet requires little maintenance. However, for best performance clean
after each use. Using 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.

SECTION 9 − TROUBLESHOOTING
Trouble
Remedy
Auto lens not ON – auto-
lens does not darken mo-
mentarily when the On
button is pressed.
Check batteries and verify they are in good condition and installed
properly.
Check battery surfaces and contacts, and clean if necessary.
Check battery for proper contact and gently adjust contact points
if necessary. This is particularly important if the helmet has been
dropped. Verify left and right battery trays are installed on the
correct sides.
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 mode 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.

Check the lens cover for dirt and spatter that may be blocking the

reduce switching.
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.
