ABSTRACT:
Improved automatic welder's helmet having pneumatic control to effect closing of the helmet's dark eye shield prior to energizing the electrode for striking the welding arc, and further to maintain the dark eye shield closed until after the arc and weldment's white afterglow have ceased. Additionally, the helmet includes a ventilation system operable to ventilate the helmet and remove annoying welding fumes and smoke from the interior thereof and about the eye shield in its lowered position on the operator's head. In a modified embodiment, the helmet ventilation system operates only when the operator is depressing the electrode holder's control button.
