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. Reset Button And Low Battery Indicator
.The auto-darkening lens turns on
(darkens) automatically when
welding begins and turns off 15 −
20 minutes after welding stops.
1 Reset Button
Press Reset button to check if the lens
is working properly.
When the Reset button is pressed, the
lens should darken twice and return to
the clear state. Do not use the helmet
if the lens does not function as de-
scribed. (See Section 9, Trouble-
shooting.)
2 Low Battery Indicator
The low battery indicator lights when
2−3 days of battery life remain.
If battery power is low, replace with
CR2450 lithium batteries (2 required)
(Hobart Part No. 770 284) (see Sec-
tion 6).

3-3. Lens Delay Control
1 Lens Delay Control
The lens delay control is used to ad-
just the time for the lens to switch to
the clear state after welding.
The delay is particularly useful in
eliminatingbright after-rays present
in higher amperage applications
where the molten puddle remains
bright momentarily after welding.
Lens delay adjusts from min (0.10
second) to max (1.0 second.).

3-4. Variable Shade Control (No. 9 −13)
1 Variable Shade Control
(No. 9 −13)
Use the control to adjust the lens
shade in the darkened state. Use
the table below to select proper
shade control setting based on
your welding process.
Start at shade 12 and adjust lighter
to suit the welding application and
your personal preference.

3-5. Sensitivity Control
1 Sensitivity Control
Weld Mode
Use control to make the lens more respon-
sive to different light levels in various weld-
ing processes. Use a Mid-Range or
30−50% sensitivity setting for most ap-
plications.
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.
STurn sensitivity control to lowest
setting.
SPress Reset button to turn helmet On.
Helmet lens will darken twice and then
clear.
SFace the helmet in the direction of use,
exposing it to the surrounding light con-
ditions.
SGradually turn sensitivity setting clock-
wise until the lens darkens, then turn
sensitivity control counterclockwise
until slightly past setting where lens
clears. Helmet is ready for use. Slight
readjustment may be necessary for
certain applications or if lens is flashing
on and off.
Grind Mode
.Do not weld in the Grind mode; the lens
will not darken.
To use the Grind mode, turn the Sensitivity
control clockwise to the far right position
(Grind). To resume welding, return the con-
trol to the desired sensitivity setting.

SECTION 4 −ADJUSTING HEADGEAR
.There are four headgear adjust-
ments: headgear top, tightness,
angle adjustment, and distance
adjustment.
1 Headgear Top
Adjusts headgear for proper depth
on the head to ensure correct bal-
ance and stability.
2 Headgear Tightness
To adjust, push in the adjusting knob
located on the back of the headgear
and turn left or right to desired tight-
ness.
.If adjustment is limited, it may be
necessary to remove the com-
fort cushion.
3 Distance Adjustment
Adjusts the distance between the
face and the lens. To adjust, loosen
both outside tension knobs and
press inward to free from adjustment
slots. Move forward or back to de-
sired position and retighten. (Both
sides must be equally positioned for
proper vision.)
4 Angle Adjustment
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.
.When using the back distance
adjustment positions, only the
back three angle adjustment
pins can be used.

SECTION 5 −REPLACING THE LENS COVERS
5-1. Replacing Outside Lens Cover
!Never use the auto-darkening
lens without the inside and
outside lens covers properly
installed. Welding spatter will
damage the auto-darkening
lens and void the warranty.
1 Front Lens Holder
2 Release Points
3 Lens Cover
4 Gasket
Remove front lens holder by press-
ing release points and pulling the
holder away from the helmet.
Remove lens cover and gasket from
the holder. Replace lens cover and
reinstall gasket and lens in holder.
Reinstall holder in helmet.
.Be sure the flat side of lens
cover gasket faces the lens cov-
er holder.
