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 strikingarc 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。

By a lot of experiment, the author claimed a soft arcstriking 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。

Before striking an arc, the welder frequently taps the end of the electrode on the ground to break away flux at the tip.
