摘　　要：本文较详细地分析了WSM－100晶体管钨极脉冲氩弧焊机的控制方法，并从理论上对系统进行了较详细的动态分析。经理论校正后的系统，具有动态响应快等特点。在小电流5A时，极易起弧，系统运行可靠、稳定。实践证明对于0．1～2mm的不锈钢板焊接，效果良好，焊缝成形美观。It' s analyzed in the article that the control method of WSM-100 thyristor TIG welder, and make a dynamic analysis to the system in theory. After theorical rectification, the system has the advantages such as fast dynamic response and so on. In case of 5A current, it is easy to start arc, the system runs stably and veliably. It is proved in Practice that to weld 0. 1-2 mm stainless steel plate, the effect is good, and weld forms Perfectly.
