AC TIG焊机引弧、稳弧电路的探讨

An Improvement About the Circuit of AC T IG Welder

在分析ACTIG焊机电路的基础上,根据焊机原电路存在稳弧效果不理想和电阻热损耗大等问题,提出了两种新的改进方案,试验结果表明,改进方案简单可行。

Two improving projects had been proposed to overcome the shortages-lack of reigrution arc energy and too much consumption of resistence heat energy-based on the analysis of the circuit of AC TIG welder. The experimental results illustrated that these projects are simple and practical.
