Use control to make the lens more
responsive to different light levels in
various welding processes. Use a
Mid-Range or 30−50% sensitivity
setting for most applications.
It may be necessary to adjust helmet
sensitivity to accommodate different
lighting conditions or if lens is flash-
ing on and off. Adjust helmet sensi-
tivity as follows:
Adjust helmet sensitivity in light-
ing conditions helmet will be
used in.
Turn sensitivity control to lowest
setting.
Press On button to turn helmet
On. Helmet lens will darken
twice and then clear.
Face the helmet in the direction
of use, exposing it to the sur-
rounding light conditions.
Gradually turn sensitivity setting
clockwise until the lens dark-
ens, then turn sensitivity control
counterclockwise until slightly
past setting where lens clears.
Helmet is ready for use. Slight
readjustment may be neces-
sary for certain applications or if
lens is flashing on and off.
