ALWAYS TEST TO BE SURE THE AUTO-DARKENING LENS IS
FUNCTIONING PROPERLY BEFORE WELDING. The TEST button
is for the user to verify the Auto-Darkening Lens is darkening
properly. If lens is not darkening properly, check shade range
switch and/or shade dual scale dial for proper shade setting. If
this does not resolve your issue, replace battery with fresh battery
and test again before use. While welding, the arc and solar cell
will keep the lens charged.
