    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.

    Abstract: A welding-type system includes a welding torch comprising a contact tip to provide an electrode wire. A secondary contact in electrical contact with the electrode wire, the secondary contact located along a length of the electrode wire and before the contact tip. Each of the contact tip and the secondary contact are connected to a welding-type power source. A current limiting device coupling located between the welding-type power source and the secondary contact and configured to limit a current at the secondary contact.
