1 Sensitivity Control
Use control to make the lens
more responsive to different
light levels in various welding
processes. Use a Mid-Range
or 50-70% sensitivity set-
ting for most applications.
It may be necessary to adjust
helmet sensitivity to accom-
modate different lighting con-
ditions or if lens is switching
on and off. Adjust helmet sen-
sitivity as follows:
F
Adjust helmet sensitivity
in lighting conditions
helmet will be used in.
l Before welding (lens in
light state), face the hel-
met in the direction of
use. If the lens switches
on and off, it is being af-
fected by the surrounding
light. Decrease sensitivity
setting.
l If lens switches on and
off during welding, the
sensitivity setting is too
low. Increase sensitivity
setting. Helmet is now
ready for use.
Slight readjustment may
be necessary for certain
applications or if lens
continues to switch on
and off.
