Moreover, the effect of the latter welding subsection's quenching arc region on decreasing residual stress of the prior welding subsection is better than the striking arc region.

中间焊段的收弧区降低先焊焊段残余拉应力的效果要优于起弧区。

This paper analyses the usage of LGK series of air plasma arc cutting machine, and enumerates the causes and solutions of striking arc, main circuit, gas path and cutting torch breakdown.

分析了LGK系列空气等离子弧切割机的使用方法，例举了其引弧故障、主电路故障、气路故障、割枪故障产生的原因和解决方法。

By a lot of experiment, the author claimed a soft arc striking technic which lead the arc ignition success rate to as high as above 90%.

作者还通过大量的试验，以软起动引弧方式，使焊机的引弧成功率达90%以上。
