Welding wire feeder with conical feeding rollers

摘要

The welding wire feed has drive rollers for the wire which are tapered to exercise pressure perpendicular to the axis of rotation of the rollers. The feed has a motor driven roller (M) to drive the wire (F) and a pressure adjuster (AP) to provide a regulated feed force onto the wire. The pressure adjuster can be a pressure roller (P) pivoting around an axis (CC) mounted on a housing (CR).
