z The ATD auto-darkening welding helmet comes assembled but before it can be used it
must be adjusted to fit the user properly and set up for response time, sensitivity and shade
level.
ADJUSTING THE FIT OF THE HELMET
z 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 to allow just the right tension to be set to keep
the helmet firmly on the head without it being too tight.
z If the headband is riding too high or too low on your head adjust the strap that passes over
the top of your head. To do this, release the end of the band by pushing the locking tab 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 tab through the nearest hole. (See adjustment “W” in fig.1)
z 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 DISTANCE BETWEEN HELMET & FACE
z Loosen the block nut to adjust the distance
between the helmet and your face with the helmet
in the down position.
z Loosen the block nut on either side of the helmet and slide it nearer to or further from your
face. It is important that your eyes are each the same distance from the lens otherwise the
darkening effect may appear uneven.
z Re-tighten the block nut when adjustment is complete.
