WELDING HELMET ADJUSTMENT
4.12.1.
Adjust the welding helmet circumference with the thumb wheel (fig 8 - 1) on the back band of the welding helmet. The thumb wheel
is locked in position. Press the thumb wheel in to unlock, then twist clockwise to tighten and counter-clockwise to
loosen. At the desired circumference release the thumb wheel back into the locked position, adjust the height by snapping the pin
on the top band (fig 8 - 2) into the required hole location to lock securely in place.
4.12.2.
To adjust the viewing angle, loosen the thumb wheels (fig 8 - 3) on both sides of the welding helmet and change the angle locker to
the desired tilt position. There are 5 pre-set positions with the head shield supplied in the mid setting.
NOTE: The welding helmet should still be free enough to be raised up, but not to drift downwards.
4.12.3.
To adjust the distance between the user's face and the welding helmet, loosen the thumb wheels (fig 8 - 3) on both sides
of the welding helmet until the headband can move back and forth freely. Position the headband into one of the 3 slots (fig 8 - 4),
as desired (the welding helmet is supplied in the mid setting). This should be completed one side at a time and both sides must be
located in the same location. Re-tighten the thumb wheels.
