SENSITIVITY CONTROL

The sensitivity control is used to make the lens more responsive to different light levels exeperienced in various welding processes. We recommend a Mid- Range or 30-50% sensitivity seting for most applications.

SENSITIVITY ADJUSTING It may be necessary to adjust helmet sensitivity to accommodate different lighting conditions or if lens is flashing On and Off. Adjust helmet sensitvity as follows

1. Turn sensitivity control to lowest setting.
2. Face the helmet in the direction of use ,exposing it to the surrounding light conditions.
3. Gradually turn sensitivity setting clockwise 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.
