Instructions for Safety, Use and Maintenance
SAFETY PRECAUTIONS - Read before using
Warning! Watch Out! There are possible hazards as shown in the
adjoining symbols.
ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the weld.
• 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 in Safety Standards). Refer to Shade and
Sensitivity charts in Section 2.
• Wear approved safety glasses with side shields under your helmet.
• Use protective screens or barriers to protect others from flash and glare; warn others not to watch the arc.
• 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.
• Use impact resistant safety spectacles or goggles and ear protection at all times when using this
welding helmet.
• Do not use this helmet while performing grinding operations, working with or around explosives or
corrosive liquids.
• Do not weld in the overhead position while using this helmet.
• Inspect the auto-lens frequently. Immediatly replace any scratched, cracked, or pitted cover lenses
or auto-lenses.
NOISE can damage hearing.
Noise from some processes or equipment can damage hearing.
• Wear approved ear protection if noise level is high.
OPERATION INSTRUCTIONS
Auto On/Off Button
Locate the ON button and press ON to weld, the lens will automatically darken twice and then return
to the light state, the helmet is then ready to weld.
Note: The lens will Auto-Off (clear state, N°3) after 45 minutes after the last arc. It will be necessary
to press the ON button to resume welding.
Variable Shade Control (N°8 - N°13)
Use the shade chart below to select proper shade control setting based on your welding process.
We recommend starting at shades 12 or 13 and adjust lighter based on the welding application and
personal preference.

Sensitivity control
The sensitivity control is used to make the lens more responsive to different light levels experienced
in various welding processes. We recommend a Mig-Range setting for most applications. See
adjusting Sensitivity and recommended sensitivity Settings sections following.
1) Press on/off Button to turn helmet on. Helmet lens will darken twice and then clear.
2) Adjust the lowest setting of sensitivity.
3) Increase the sensitivity pushing the button
4) When the lens turns dark, decrease the sensibility from 1 step
Helmet is ready for use. Slight readjustment may be necessary for certain applications or if lens is
flashing on and off.

Lens Delay Control
The lens delay control is used to slow the lens-switching time to the clear state after welding.
The delay is particulary useful in eliminating bright after-rays present in higher amperage applications
where the molten puddle remains bright momentarily after welding. Adjusts from (.10 second-Min. to
1.0 second-Max).
Low Battery Indicator
The low battery indicator lights when 2-3 days of battery life remain. Replace the battery with a
readily available coin type CR2450 Lithium Battery or equivalent. Cat N° W000260920
Adjusting Headgear for Maximum Comfort
There are four headgear adjustments: headgear top, tightness, distance adjustment, and angle
adjustment.
1. Headgear Top: Adjusts headgear for proper depth on the head to ensure correct balance and
stability.
2. Headgear Tightness: To adjust, hold the adjusting knob located on the back of the headgear and
turn left or right to desired tightness.
3. Distance Adjustment: Adjusts the distance between the face and the lens. To adjust, hold both
tension knobs and move forward or back to desired position. (Both sides must be equally positioned
for proper vision.)
4. Angle Adjustment: 6 Locations for the arm tap on the right side of the headband top provide
adjustment for the forward tilt of the helmet by each 8°. To adjust, lift
the control arm tab and move it to the desired position. Retighten
tension adjustment knob.
