<p>A compressible end-fitting (28) for a welding gun liner includes a tubular body (32). A head (36) is disposed at an end of the tubular body (32). The head (36) is wider in diameter than the tubular body. A sleeve (42) is disposed around the end portion of the tubular body that includes the head. The sleeve (42) includes a stepped inner surface (46) defining a shoulder (48). At least one biasing member (50) is disposed between the head and the shoulder. The biasing member(s) (50) urges the head (36) outwardly away from the sleeve (42). An annular stop (52) on an outer surface of the tubular body is contactable with an edge of the sleeve (42) to limit movement of the head (36) relative to the sleeve (42). The head (36) is linearly retractable from a resting position into the sleeve (42) by application of an axial force, and the biasing member(s) (50) returns the head (36) to the resting position when the axial force is removed.</p> |
