ABSTRACT:
A welding helmet having a headband that fits upon a head of a welder, and a face shield with a viewing port having a light filtering window that pivots on the headband between a raised up non-shielding position and a lower down shielding position has an automatic lighting system with a power source component secured to a interior bottom surface of a top portion of the face shield, and an illumination component secured to a top exterior surface of the top portion of the face shield for lighting a work area outside the helmet. The energizing of the lighting system is responsive to the position of the raising and lowering of the face shield of the helmet so as to permit the welder to better perceive his/her surroundings.
