摘要
方波交流ＴＩＧ焊时，电流正负半波比例可调，对于减少钨极烧损和提高焊接速度有着非常重要的作用。本文为实现电流正负半波比例的可调性而对控制电路进行了设计和研究。
In the square wave current TIG welding,the current′s proportion is adjusted to posstive/negative half wave.It is important to reduce wolfran electrode weariness and improve the welding rate.This paper maily studies the control circuit to realizz the current′s proportion being adjusted between posstive and negative half wave.
