Use control to make the lens more respon-

sive to different light levels in various weld-

ing processes. Use a Mid-Range or

30−50% sensitivity setting for most ap-

plications.

It may be necessary to adjust helmet sensi-

tivity to accommodate different lighting con-

ditions or if lens is flashing On and Off. Ad-

just helmet sensitivity as follows:

Adjust helmet sensitivity in lighting con-

ditions helmet will be used in.

Turn sensitivity control to lowest

setting.

Press Reset button to turn helmet On.

clear.

Face the helmet in the direction of use,

exposing it to the surrounding light con-

ditions.

Gradually turn sensitivity setting clock-

wise until the lens darkens, then turn

sensitivity control counterclockwise

until slightly past setting where lens

clears. Helmet is ready for use. Slight

readjustment may be necessary for

certain applications or if lens is flashing

on and off.

will not darken.

To use the Grind mode, turn the Sensitivity
