- 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.

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.

The sensitivity can be set to high or low by using the infinitely
dial knob on the back of the shade cartridge. The High setting
is the normal setting for everyday use. The maximum
sensitivity level is appropriate for low welding current work, TIG
or special applications. Where the operation of the helmet is
disturbed by excess ambient light, or another welding machine
close by, use the low setting (See fig.3).
When welding ceases, 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 to SHORT (0.1 sec) or
(0.1 sec). As you require using the switch knob on the
back of the shade cartridge (See fig.3). 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 in order to avoid
the filter opening when the light path to the sensors is
temporarily obstructed by a hand, torch, etc.
