Function
The Auto-Darkening Welding Helmet is designed to protect the eyes and face from sparks, splatter, and
harmful radiation under normal welding conditions. The Auto-Darkening Filter automatically changes from
a clear state to a dark state when an arc is struck, and it returns to the clear state when welding stops.

Before Welding

The Auto-Darkening Welding Helmet comes ready
for use. The only things you need to do before
welding are to remove the protective film from both
sides of the lens (if not already done), adjust the
position of the headband, select the correct shade
number for your application, and test the helmet
for proper operation as described following.
Check the Front Cover Lens to make 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 Cover Lens and the Front Lens Retaining Frame,
and make sure that they are secured in place.
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.
