The drain-source voltage (Fig. 28) starts oscillating at the end of the flyback phase and reaching the minimum of 100V when the MOSFET turns on.

Near the critical point of the RLC-circuit, the residual voltage waveform changes form non-oscillating attenuation mode to distinct across zero oscillating mode when the peak current increases.
在RLC回路临界点附近，随着冲击电流峰值的增大，残压波波尾从非振荡衰减过渡到大幅度的过零振荡；

When the wire feed is pausing in each oscillating cycle, the output voltage of power source is a peak value and the wire is melted under the welding voltage, forming a droplet metal.
