Abstract:
1. A welding helmet apparatus that has an outer surface that encloses the front, right side, left side, top and back of the welding operators head and comprises: a) an auto-darkening lens located in the front portion of said helmet that when an electric arc is present changes from transparent to a dark shade providing adequate protection from the harmful effects of arc rays, and b) a headband to allow the helmet apparatus to be adjusted to fit different individuals, and c) an air filter to capture harmful particles of welding fume and prevent them from passing through said air filter, and d) an electric motor powered fan contained within said helmet apparatus, and e) an integral air passageway having a entry end and an exit end, and f) said air filter is located at said entry end of said air passageway, and g) said electric motor powered fan is located at said exit end of said air passageway, and h) a thermal electric cooling module is located in said air passageway such that the cooling surface of said cooling module is located in said passageway, and i) a heat-dissipating surface of said cooling module is located on the outside surface of said helmet apparatus, and j) said helmet obtaining power from an AC/DC power converter to keep voltage in said helmet below 24 volts, said AC/DC power converter connected to a ground source while obtaining welding power directly from either a MIG wire feeder at a point where welding power is available or from a stick electrode power line where welding power is available, said welding power obtaining power from a separate AC or DC welding power supply.
