Polarity switching method in consumable electrode AC pulse arc welding

A polarity switching control method is provided for consumable electrode AC pulse arc welding. By the method, a peak current and a base current are applied during an electrode-positive polarity period, while an electrode-negative current is applied during an electrode-negative polarity period. For p...
