ABSTRACT:
A welder's helmet having a plurality of photovoltaic cell panels, responsive to light produced during welding operations, for driving a pair of fans secured to opposing side walls of a head protecting shell. The photovoltaic cell panels are angularly mounted to the shell beneath a viewing window provided therein so as to permit the head of the wearer to be turned away from the welding area without affecting fan output. During operation, each of the paired fans impels air through an opening in the shell into the interior space defined by the shell. An optional battery pack, electrically connected to the fan motors provides an electrical power back-up for energizing the fans in the event that insufficient light is available to the photovoltaic panels.
