*Based on ANSI/ASC Z49.1, AWS F2.2-89. Shade numbers are given as a guide only and may be varied to suit application needs.
Consult your on-site training officer, industrial hygienist, or safety manager.
** Protection from optical radiation is directly related to filter lens density. Select the darkest shade that allows adequate task performance.
As a rule of thumb, start with a shade that is too dark to see the weld zone. 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 in 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.
