发明名称 Shock resistant light for MIG welder
摘要 A light for MIG welders. The light is provided by a low voltage high intensity halogen lamp and parabolic reflector to focus the concentrated light beam on the work area at an intensity comparable to that of the welding arc to provide visibility through the user's shield. The light is provided with a clamp for ready attachment to the welding gun and has an adjustment for shifting the focus with a toggle and spring biased shock resistance. To resist thermal shock a pyrex lens may be employed or a tungsten screen which further resists spatter. Ventilation is provided by openings in the reflector and the tungsten screen.
