Adjusting Sensitivity

Sensitivity/Grind Mode Control (Auto-On Lens Assembly) Sensitivity Control (Manual-On Lens Assembly)

The sensitivity control is used to make the lens more responsive to differing light levels experienced in various welding processes. We recommend a Mid-Range or 30−50% sensitivity setting for most applications. See Ad- justing Sensitivity and Recommended Sensitivity Settings sections following.

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

.Adjust helmet sensitivity in lighting conditions helmet will be used in.

1 Turn sensitivity control to lowest setting.

2Press Reset button (Auto-On Lens) or On/Off button (Manual-On Lens) to turn helmet On. Helmet lens will darken twice and then clear.

3Face the helmet in the direction of use, exposing it to the surrounding light conditions.

4Gradually 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 neces- sary for certain applications or if lens is flashing on and off.

Using Grind Mode (Auto-On Lens)

To use the Grind mode, turn the Sensitivity control clockwise to the far right position (Grind). To resume welding, return the control to the desired sensitiv- ity setting.

.Do not weld in the Grind mode; the lens will not darken.
