Wire feeder for welding

Abstract:

A wire conveying mechanism, preferably for a welding, cladding or additive manufacturing apparatus, with a slip clutch mechanism connectable to a motor. Such a wire conveying mechanism may include a wire feeder for feeding an electrode wire in a welding system having a drive roller assembly comprising a plurality of drive rollers to grip the electrode wire and to pull the electrode wire from an electrode wire source toward a conduit and a torque-managing device operatively coupled between a motor and the drive roller assembly, wherein the torque-managing device receives the rotational force from the first motor and regulates the first torque to output a second torque to the drive roller assembly.
