(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
Shade numbers are given as a guide only and may be varied to suit individual needs.
