Adjusting Headband

Adjust the Headband so that the helmet is seated securely on your head as low as possible and close to your face.

Adjust the Headband width by turning the Ratcheting Headband Knob to make sure the Front Cover Lens is aligned with your eyes.

Adjust the Headband height by tightening or loosening the top strap until the Helmet fits snug on your head. Once the Headband is properly adjusted, lower the Helmet over your face until the proper angle is found. Then turn the Tension Adjustment Knobs on either side of the helmet, locking the helmet’s angle in place.

Time Delay and Sensitivity

At the moment the welding operation is started, the filter screen automatically changes from clear to dark.

The operator can vary the amount of time it takes the filter to return to a clear state and the sensitivity of the sensor using the controls inside the helmet.

The Sensitivity setting changes the amount of light needed to make the filter react.

Filters

The ultra high performance of UV and IR Auto- Darkening filters provides to user’s eyes and face full protection against UV and IR radiation during entire welding process, even in clear state. The UV/ IR protection level is up to shade 16 at all times.

Magnifying Cheater Lens

A Cheater Lens (sold separately) can be attached to the inside of the helmet by unhooking the wire bar at the bottom of the Inside Lens Cover, sliding the Cheater Lens in place, then securing it with the wire bar.
