The Auto-Darkening Welding Helmet needs to be charged prior to use and after
extended storage.
Leave the solar panel on the helmet facing the sun for at least 4
hours before first use.

2.

Remove the protective film from both sides of the front lens (if not already done).

1.

Check the Front Lens Cover to makes sure that it is clean, and that no dirt is covering
the two sensors on the front of the Filter Cartridge. Also, check the Front/Inside Lens
Cover and the Front Lens Retaining Frame, and make sure that they are secure in place.
Check for light tightness before each use.

Inspect all operating parts before each use for signs of wear or damage. Any scratched,
cracked, or pitted parts should be replaced immediately before using again to avoid
severe personal injury.

3.

Select the shade number you need for your setting at the turn of a shade knob - see

shade number for your application.

Note: If a selection of shades are recommended

Adjust headband so that the helmet is seated on the head as low as possible and close
to your face. Adjust helmet’s angle when in the lowered position by turning the adjustable
limitation washer.

IMPORTANT NOTE: Test the helmet auto-darkening filter lens before welding.
While wearing the helmet, briefly strike an arc, keeping your face and eyes turned
slightly away, and to one side. The lens should darken evenly when not directly
facing the arc. If it does not darken properly, do not use the Welding Helmet.
