Abstract
A welding wire feeder including an alignment tongue and groove connection between a clamp arm and a welding drive assembly housing is provided. In certain embodiments, an alignment tongue extends from an end of the clamp arm opposite a pivot point about which the clamp arm rotates relative the assembly housing. A corresponding alignment groove may be formed in the assembly housing to receive the alignment tongue when the clamp arm is rotated such that a drive wheel mounted on the clamp arm contacts a drive wheel mounted on the assembly housing. In addition, a tensioner may be pivoted into a groove in the clamp arm to transfer a compressive force through the clamp arm, forcing the drive wheels together. The alignment tongue and groove may reduce lateral displacement of the clamp arm relative to the assembly housing that may be caused by a force transferred to the clamp arm as the tensioner is pivoted.
