Step 3: Re-tighten the block nut when
adjustment is satisfactory.
ADJUSTING VIEW ANGLE
There are 5 holes on both sides of the helmet
(see Fig.2). You can change view angle position
by moving the adjustable limitation washer into
different holes.
SELECTING SHADE LEVEL
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.

SELECTING DELAY TIME
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 "S"
(short: 0.1 sec.) or "L" (long: 1.0 sec.). As
you require using the infinitely dial knob on
the back of the shade cartridge (see Fig.3a).
It is recommended to use a shorter delay
with spot welding applications and a long
delay with applications using higher currents.
Longer delays can also be used for lower
current TIG welding, and TIG / MIG / MAG
pulse.

SENSITIVITY
The sensitivity can be set to " H "(high) or " L
"(low) by using the infinitely dial knob on the
back of the shade cartridge. The "Mid-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.3b). As a simple
rule for optimum performance, it is recomme-
nded to set sensitivity to the maximum at
the beginning and then gradually reduce it,
until the filter reacts only to the welding light
flash and without annoying spurious trigge-
ring due to ambient light conditions (direct
sun, intensive artificial light, neighbouring
welder's arcs etc.).
SELECTING THE GRIND OPTION
When the shade knob is turned to the "grind"
position, the shade function is turned off
allowing a clear view to grind a weld with the
helmet providing face protection. Before
restarting welding work, Ensure that the
shade function is turned back on before
welding again (see Fig.4).

TEST
Press and hold test to preview shade selection
before welding (see Fig.5). When released
then viewing window will automatically return
to the light state (3.5 Shade).
POWER
This ADF cartridge is powered by solar cell
and 2 AAA alkaline batteries. Replace batteries
when LOW BATTERY light is lit (see Fig.5).
You are now ready to use the helmet. The
shading may be adjusted during use by
re-setting potentiometer control.
