| 1. | At last , an experiential power supply was made , and a series of experiments is done . a lot of high - frequency pulse current was superposed on dcen current , modulated the welding current waveform we required and optimized the energy distribution , which satisfied the basic requirement of cathode cleaning 最后制作了一台实验电源,并进行了一系列的电弧实验,通过在变极性电源电流dcen基础上叠加一系列脉冲电流,调制出所需电流波形,实现输出能量的最优分配,在满足阴极清理的前提下,最大限度地提高焊接效率。 |
