A welding gun inlet for use with a welding gun power pin of a welding gun. The welding gun inlet includes an inlet body which has a first end and a second end and a tapered outer wall which generally tapers downwardly from a relatively larger diameter portion adjacent the first end to a relatively lesser diameter portion adjacent the second end. The welding gun inlet further includes an insertable member which extends outwardly from the inlet body. The insertable member has a length and defines a relatively constant cross-sectional diameter along at least a major portion of the length of the insertable member.
