摘要

An arc welding apparatus comprising a conductor tube (454) defining an internal passageway (504) is disclosed. The conductor tube (454) further defines an external surface (506) profile and a distal end portion (466). The conductor tube (454) is configured to engage a sleeve (458) having inner (468) and outer surface (460) profiles. The inner surface profile (468) is configured to abut the external surface (506) profile of the conductor tube (454), and the outer surface profile (460) comprises an engaging portion.
