3-3. Lens Delay Control
1 Lens Delay Control
The lens delay control is used to
adjust the time for the lens to switch
to the clear state after welding.
The delay is particularly useful in
eliminating bright after-rays pres-
ent in higher amperage applica-
tions where the molten puddle re-
mains bright momentarily after
welding. Lens delay adjusts from
min (0.10 second) to max (1.0 sec-
ond.).
