ALWAYS TEST TO BE SURE THE ADF CARTRIDGE IS CHARGED BE-
FORE WELDING.
The
TEST
button is for the user to verify the ADF cartridge
is darkening properly. If cartridge is not darkening properly, replace batteries
with fresh batteries and test again before use. While welding, the arc and solar
cell will keep the ADF charged.
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.

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.
