Collet and nut assembly for stud welder

摘要

A collet and nut assembly for a stud welder in which the body of a tubular nut has an extension sleeve that surrounds a tubular collet having longitudinal tangs separated by slots. Relief holes at base ends of the slots are inside the nut, and maximum stress on the collet is redistributed away from the relief holes. The nut may have a further tubular extension forming a cover for the collet, with a face that protects the tip of the collet from weld spatter and soot. The cover also protects the collet from heat.
