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, cutting, or
brazing where the torch and/or the flux produces a high yellow light, it is desirable to use a filter lens that
absorbs the yellow or sodium line of the visible light spectrum.
