The current is variable polarity current, The zero pass speed is rapid and it is propitious to arc stiffness; The amplitude and time of plus-minus semi-vave can be accommodated independently. Under the condition of forming well catelectrode atomizationt, Tungsten electrode burning loss can be reduced in high limit,foming perfect welding process.
其电弧电流为变极性电流,电流过零速度快有利于电弧稳定;电流正负半波幅值和时间均可独立调节,在形成良好的阴极雾化作用的情况下,可以最大限度的减少钨极烧损,形成良好的焊接过程。
