Zusammenfassung:	The utility model relates to an AC electric welding machine, which comprises a AC welding machine B[2], a power compensating capacitor C[2]. The utility model is characterized in that: the utility model also comprises a excitation capacitor C[1], a trigger starting circuit, a power supply switching circuit and a DC circuit. The trigger starting circuit in-put end is connected with one end of secondary AC welding machine B[2] and the out-put end is connected with the input end of the power supply switching circuit. The input end of the DC circuit is connected with the power end of the AC circuit and the output end of the DC circuit is connected with the power supply switching circuit. The power compensating capacitor C[2] is parallel connected on one side of the AC welding machine B[2]. The excitation capacitor C[2] is series connected with a parallel circuit on one side of the AC welding machine B[2]. Proved by experiment, the utility model is reasonable in structure, easy in manufacture, low in cost, stable in performance, long-lasting and convenient for expanding.
