SYSTEMS AND DEVICES FOR POWER COMMUTATION IN WELDING TORCHES

摘要

A welding torch (28) includes an electrical commutation device (74) configured to receive welding power. The electrical commutation device (74) is also configured to transfer the welding power between a welding power input and welding wire (56) before the welding wire passes through a guide device (58) that directs the welding wire (56) out of the welding torch.
