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.

OM-234 388 Page 5

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.

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

Start at the highest setting and ad-

just lighter to suit the application

and your personal preference.

Use the table below to select prop-

er shade control setting based on

your welding process.

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.

805 010

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

Grinding No sensitivity setting; use Grind mode

OM-234 388 Page 8

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.
