• Welding helmet slips
Headband is not properly adjusted. (Readjust the headband.)
• The helmet comes assembled, but before it can be used it must be adjusted to t the user
properly and set up for delay time, sensitivity and shade level.
• 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 while
wearing the helmet and allows just the right tension to be set to keep the helmet rmly 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 pin
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 pin through the nearest hole (see adjustment “W” in Fig. 1).
• Test the t 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 both the same
distance from the lens. Otherwise the darkening effect may appear uneven.
Step 3: Re-tighten the block nut when adjustment is complete.
WARNING
The user must stop using the auto-darkening welding helmet immediately if the
above-mentioned problems cannot be corrected. Contact the dealer.
INSTRUCTIONS FOR USE
WARNING! Before using the helmet for welding, ensure that you have read and
understood the safety instructions.
