【摘要】 本文结合TIG焊的特点，对其使用的接触式引弧、高压高频引弧及高压脉冲引弧的性能和应用范围进行了分析和对比。并对高压高频引弧的最佳频率范围提出了实验数据。本文还介绍了英国、日本、前苏联及作者自己研制的七种新型引弧器。更多还原

【Abstract】 According to the characteristics of the TIG welding, author analyzed and compared the functions and aPPlying ranges of the direct touch igniting、high voltage- high frequency igniting and the high voltage pulses igniting. Through testing the optimum frequency range of the high voltage- high frequency igniting has been put forwarded. given new type ignitores of British. Japan. Russion and developed by author hi~lf is introduced in the paper too.更多还原
