变极性方波电源研制

The Study of Variable Polarity Power Source

变极性交流方波电源是当前铝合金材料焊接的最佳设备。通过研制，对该电源的实施方案、组成部分及调试中的一些问题进行了试验分析，得到了初步结果，为今后开发提供了极其重要的依据。

The variable polarity AC square wave power source is best equipment for aluminium alloy welding. Through studing the implementing method、the compoment parts of this power source and the problem in exprementing we get some primary results that give us impotent basis.
