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.

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

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.
Data from ANSI Z49.1-2005
If your helmet does not include any one of the shades referenced above, it is
recommended you use the next darker shade.
