高频引弧器及其对逆变直流氩弧焊机干扰性能的研究

Research of High Frequency Arc Starter and Its Interference to DC Inverted Tig Welder

分析了传统高频高压引弧电路对直流氩弧焊机产生干扰的原理,为了减少干扰,又提出了一种新的高频引弧装置———高压脉冲引弧电路。实验表明,新的高频引弧电路具有干扰小、易起弧等特点。

s:This article analyzes the interference principle of HF & HV arc starter to DC inverted tig welder and presents a new class of HF arc starting circiut It is verified by experiments that the new arc starter has the advantage of easier ingition and less interference to welder
