This Auto-Darkening filter Welding Helmet is designed to protect the eyes and face from sparks, spatter,
and harmful radiation under normal welding conditions. Auto-darkening filter automatically changes
from a light state to a dark state when an arc is struck, and it returns to the light state when welding
stops.
Auto-Darkening filter Welding Helmet comes ready for use. The only thing you need to do before
your welding is to adjust the position of the headband and select the correct shade number for your
application.

are clean, and that no dirt is covering the two
sensors on the front of filter cartridge. Also check
the front/inside cover lens and the front lens retain-
ing frame to make sure that they are secure.
• Inspect all operating parts before use for signs
of wear or damage. Any scratched, cracked, or
pitted parts should be replaced immediately be-
fore using again to avoid severe personal injury.
