CAUTION: Do not allow persons to operate or assemble this auto darkening welding
helmet until they have read this manual and have developed a thorough understanding of
how the welding helmet works.

manual cannot cover all possible conditions or situations that could occur. It must be
understood by the operator that common sense and caution are factors that cannot be built into this
product, but must be supplied by the operator.
SAVE THESE INSTRUCTIONS
IMPORTANT SAFETY CONSIDERATIONS
• Should this helmet not darken upon striking an arc, stop welding immediately and contact your
supervisor or your dealer.
• Use only at temperatures: -10º C ~ +55º C (14°F ~ 131°F)
• Storage temperature: -20º C ~ +70º C (- 4°F ~ 158°F)
• Regularly replace the front cover lens if it becomes cracked/ scratched/pitted.
• The materials which may come into contact with the wearers skin, can cause allergic reactions in
some circumstances.
ADJUSTING THE FIT OF THE HELMET
The overall circumference of the headband can be made larger or smaller by rotating the knob on
the back of the headband. (See adjustment “Y” in fig.1). This can be done whilst wearing the helmet
and allows just the right tension to be set to keep the helmet firmly on the head without it being too
tight.
• If the headband is riding too high or too low on your head, adjust the strap which passes over the
top of your head. To do this release the end of the band by pushing the locking pip out of the hole in
the band. Slide the two portions of the band to a greater or lesser width as required and push the
locking pip through the nearest hole. (See adjustment “W” in fig.1).
• Test the fit of the headband by lifting up and closing down the helmet a few times while wearing it.
If the headband moves while tilting, re-adjust it until it is stable.
ADJUSTING THE DISTANCE BETWEEN THE HELMET AND THE FACE
Step 1: Undo the block nut (See “T” in fig. 1) to adjust the distance between the helmet and your
face in the down position.
Step 2: Loosen the block nut on either side of the helmet and slide it nearer or further from your face.
(See adjustment “Z” in fig.1). It is important that your eyes are each the same distance from the lens.
Otherwise the darkening effect may appear uneven.
Step 3: Re-tighten the block nut when adjustment is complete.
ADJUSTING VIEW ANGLE POSITION
Please see fig.2.
SELECTING SHADE LEVEL
Select the shade level you require according to the welding process you will use by referring to the
“Shade Guide Table” below for settings. Turn the shade control knob on the side of the helmet to the
shade number required.
You are now ready to use the helmet.
