摘　　要：根据气体放电理论,结合铝合金方波交流等离子弧立焊控制系统的电磁兼容性设计,研制的新型高压脉冲引弧器,可击穿8mm空气隙,引弧可靠性极高,且体积小、成本低、实用性强。According to the theory of gas dischage in combination with electromagnetical compatibility design for controlling system of square wave AC plasma arc vertical welding of aluminium alloy, a new igniter of high voltage pulse is developed out. It can breakthrough 8mm air gap with high ignition efficiency and has merits of small volume, low cost and wide suitability.
