V. Operating Instructions
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 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.

5. Important Note: Test the helmet auto-darkening filter lens
before welding. While wearing the helmet, briefly strike an

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.
