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.).

OM-240 362 Page 5

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.

Recommended Sensitivity Settings

Stick Electrode Mid-Range

Short Circuiting (MIG) Low/Mid-Range

Pulsed & Spray (MIG) Mid-Range

Gas Tungsten Arc (TIG) Mid/High-Range

Plasma Arc Cutting/Welding Low/Mid-Range

Grind Mode Grind Position −Far Right (Clockwise)

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.

8804 814 / 804 816

Be sure flat side of gasket

faces lens cover holder.
