| Abstract: | in this paper, some problems about the stability and controlling method of the AC MIG arc are discussed. In order to improve the stability of the AC MIG arc,four methods to control AC MIG arc are designed and compared with each other theoretically and practically.The stability of the AC MIG arc is closely related to the current before the polarity reversing point and voltage after that point. |
