| Abstract: | This paper introduces the operation principle of a variable polarity plasma arc welding power source.The effects of square wave frequency and ratio of current polarity on arc stability, cathode cleaning action and heat input were investigated by experiment. ltis shown that,in this power source,the frequency,ratio of current polarity and the amplitudes of both positive and negative cycles can be adjusted respectively, at the sametine, the higher frequency pulse current can be superposed to square wave a.c.during weldign. this power source is a kind of ideal power source for welding Qluminium alloys. |
