ABSTRACT:
An electric welding torch (10) with an internal viewing system is provided an annular arc light reflector (34) to reflect light from the arc (30) back onto the workpiece. The reflector (34) has a vertical split or gap (40) in its surrounding wall to permit adjacent wall ends forming the split (40) to be sprung open slightly to permit the reflector to be removed or slipped onto the torch housing or gas cup (24). The upper opening (25) of the reflector (34) is slightly smaller than the torch housing or gas cup (24) and therefore, when placed on the torch housing or gas cup (40) has that springiness to cause it to clamp tightly on the housing or gas cup (24). The split or gap (40) also serves to permit the feed of weld wire therethrough to the weld area.
