ATD-3721
XL "SOLAR" AUTO-DARKENING HELMET
READ & UNDERSTAND ALL INSTRUCTIONS BEFORE USING
The ATD Auto-Darkening Welding Helmet is designed to protect the eyes and face from sparks,
spatter, and harmful radiation under normal welding conditions. The 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.
The ATD auto-darkening welding helmet comes ready for use. The only thing you need to do
before you weld is to adjust the position of the headband and select the correct shade number
for your application.

welding / cutting processes.
