Grind Mode − No sensitivity adjustment
The delay is particularly useful in eliminating bright after-rays present in higher amperage applications
where the molten puddle remains bright momentarily after welding. Use the Lens Delay Control buttons
to adjust delay from 0 to 10 (0.1 to 1.0 second). When welding stopped, the viewing window
automatically changes from dark back to light but with a pre-set delay to compensate for any bright
afterglow on the workpiece. The delay time / response can be set from Level 0 to level 10. It is
recommended to use a shorter delay with spot welding applications and a longer delay with
applications using higher currents. Longer delays can also be used for low current TIG welding, and
TIG / MIG / MAG pulse.
• 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.6). This can be done while 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 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.6).
Front and back bands will automatically self-adjust according to head form, and soft pads suit the
forehead and back of head perfectly, which will bring more comfort (See fig.7a). 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: Press down and hold the "LOCK" latch on both sides (See fig.7b) and it can be slide back
and forth.
Step 2: Loosen the "LOCK" latch and keep it snap into slots. Please make sure the distance
between the lens to both eyes is equal, to avoid uneven darkness.
• ADJUSTING VIEW ANGLE POSITION
Tilt adjustment is located on the right side of the helmet. Loosen the right headgear tension knob and
adjust the lever forward or back to the proper position. Re-tighten the right headgear tension knob (See
fig.7c).
