Beschreibung
Zusammenfassung:	An alternating current arc striking control circuit comprises a control module, a driving module, a first switch module, a second switch module, a third switch module, a fourth switch module, a small pulse signal output module, a positive arc striking signal end, a negative arc striking signal end, a first output end and a second output end. The driving module is provided with two driving output ends, the control end of the first switch module and the control end of the third switch module are both electrically connected with one driving output end, and the control end of the second switch module and the control end of the fourth switch module are both electrically connected with the other driving output end; the small pulse signal output module is used for outputting small pulse signals, and two output ends of the small pulse signal output module are electrically connected with the first output end and the second output end respectively. According to the utility model, small pulse current signals can be outp
