  • Light shield for welding
    Patent number: 7029136
    Abstract: A light shield for eye protection in the welding process comprises a holding unit, a base plate, a filter plate and a universal joint. The filter plate, in conjunction with the base plate, is mounted on a universal joint by which the tilt angle thereof with respect to the holding unit can be free adjusted. Since the filter plate is applied closely to the welding target, the area thereof is small, significantly reducing the weight of the light shield. The base plate further includes a lamp for illuminating the welding target, so that welding can be conveniently done in dark places. The holding unit is for retaining a hand of a user, leaving the fingers of the hand for handling other parts.
