PUSH-PULL WELDING WIRE FEEDING SYSTEMS

摘要

Welding wire feed systems include a wire feeder including a push motor (76) and a welding torch assembly including a pull motor (82) are provided. The push motor (76) is adapted to establish a wire feed from a wire spool, and a first controller (72) is adapted to receive a commanded speed level and to control operation of the push motor (76) to operate at the commanded speed level. The pull motor (82) is adapted to cooperate with the push motor (76) to establish a desired wire feed rate from the wire spool to the welding torch assembly. A second controller (79) is adapted to receive an operational speed level of the push motor (76) from the first controller (72) and to control operation of the pull motor (82) to operate at the received operational speed of the push motor (76).
