Abstract
A wire feeder including a housing having wire inlet and outlet regions. In some approaches, a tensioning assembly includes a pivotable tension arm and a pivotable tension knob assembly. The pivotable tension arm has a pivot axis oriented perpendicular to the direction of a wire fed through the wire feeder, while the pivotable tension knob assembly has a pivot axis oriented parallel to the direction of the wire fed through the wire feeder. A roller assembly includes a drive roller rotatably coupled to the pivotable tension arm, and a feed roller coupled to the housing. The feed roller is positionable opposite the drive roller to receive a welding wire therebetween and to move the welding wire from the wire inlet region to the wire outlet region. A gear assembly transmits rotational motion from a motor to the feed roller.
