Figure 4 is an example of the waveform of the arc power (instantaneous energy value). The circuit conditions are same as Figure 3. The arc power waveform kept rising, and after 4ms from the arc beginning reached the maximum value of 3300W. The arc energy Ea is obtained by integrating the instantaneous power as shown in Equation (1).
