CARTRIDGE OPERATION/FEATURES
Variable Shade Control
The shade can be adjusted from shade 5 to 8 and 9 to 13 based upon welding
process or application (refer to shade selection chart on page 6). Shade is
adjusted by setting the shade range switch to the proper range, then use the
shade dual scale dial to set the desired shade. The shade range switch and dual
scale dial are located on the ADF cartridge as shown below.

Test Button

Press and hold test to preview shade selection before welding. When released
the viewing window will automatically return to the light state (3.5 Shade)
Sensitivity Knob
Adjust the light sensitivity by turning the SENSITIVITY knob to the left or right as
shown in the figure below. Turning the knob to the left increases sensitivity
which makes the ADF cartridge more sensitive to light. When helmet is used
in the presence of excess ambient light or with another welding machine close by,
improved helmet performance can be obtained with a lower setting by turning the
knob to the right to reduce the sensitivity.
Delay Time Knob
This control is designed to protect the welder's
eyes from the strong residual rays after
welding. Changing the DELAY Time knob will
vary the dark to light time between 0.1 second
(S) to 1.0 second (L). The L setting is
recommended for high amperage applications
where the weld puddle is still very bright after
the welding arc has ceased and for situations
where the filter may be temporarily blocked
from seeing the welding arc.
Power
This ADF cartridge is powered by two
replaceable batteries and solar power. The
batteries are located at the bottom of the ADF
cartridge. Replace batteries when LOW
BATTERY light is lit. See the specification
chart on page 3 for type of batteries required.
