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 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
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.
