摘要

Arc welding device comprises: a welding current source (1) having a static or dynamic behavior; and an intelligent commutator (3) having an interconnected throttle (4) joined to a meter rectifier (5). The actual voltage signal is used as the return for the welding current source. Preferred Features: The device is operated with a constant current characteristic directly before, during and directly after polarity change.
