ABSTRACT:
The present invention is directed to an improved integral sheet metal welding pin particularly adapted for use with automatic welding machines of the type in which pins are stored in random fashion in a hopper. The pin incorporates a shank adapted to be attached by resistance welding to sheet metal ducting, and includes an enlarged head spaced from the duct and adapted to press insulation against the duct. The improved pin is characterized by an elongated tongue portion struck from the head of the pin and lying in parallel spaced relation to the shank, the configuration of the tongue and its location being such as to prevent stacking or nesting of weld pins in a manner which would preclude their being separated for automatic feeding, the tongue also serving as a stop in the course of welding, to preclude over-melting of the shank or damaging of the insulation.
