Abstract
In a consumable electrode gas shielded arc welding system, alternating current power is applied across the electrode and the base metal. The period during which the electrode is kept negative is varied to correspond to the electrode feeding rate. In addition, the levels of the output power during the negative and positive periods are individually set.
