CARTRIDGE OPERATION/FEATURES
Variable Shade Control
The shade can be adjusted from shade 9 to 13 based upon welding process or
application (refer to Shade selection chart on page 6). The variable shade control
knob is mounted to shell for external adjustment.
Sensitivity Control
You can adjust the light sensor by selecting the HIGH or LOW position of the
sensitivity switch as shown in figure below. Generally, the HIGH setting is select-
ed for normal use. Where the helmet is used in the presence of excess ambient
light or with another welding machine close by, the LOW setting may be selected
for better performance.
Delay Time Control
This control is designed to protect the welder’s eyes from the strong residual rays
after welding. You can delay the time of change to light state from the darkened
state with setting delay control switch on FAST or SLOW. The SLOW 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.
Solar Power
This helmet is powered by solar energy. As such, there is no battery that requires
replacement.

ALWAYS TEST TO BE SURE THE ADF CARTRIDGE IS CHARGED
BEFORE WELDING. The helmet can be placed in sunlight to charge. Do not
store the helmet in a dark cabinet or other storage area for long periods.
While welding, the arc also charges the ADF cartridge.
SHADE GUIDE SETTINGS
If your helmet does not include any one of the shades referenced above, it is
recommended you use the next darker shade.

(1)
As a rule of thumb, start with a shade that is too dark, then go to a lighter shade which gives sufficient view of the weld zone without going
below the minimum. In oxyfuel gas welding or cutting where the torch produces a high yellow light, it is desirable to use a filter lens that absorbs
the yellow or sodium line the visible light of the (spectrum) operation
(2) These values apply where the actual arc is clearly seen. Experience has shown that lighter filters may be used when the arc is hidden by the
workpiece.
