摘要
本文介绍一种晶闸管弧焊电源外特性的控制电路，使其外特性的斜率和拐点分别可调，可适用于高纤维素焊条的焊接要求。
The external characteristic control circuit of SCR arc welding rectifier hasbeen introduced in this paper. The slope and inflection point of external characteristic can be adjusted separately. It is suitable for the welding requirements of high cellulose electrode.
