when your CNC give out START signal,the control circuit control the motor down,when the torch contact the mild steel,the torch up and start the pierce process.if you should use a pot to control the time of torch up.
in the cutting process,the control circuit check the voltage between steel and the torch,compare with the AVC SET,if the actual AVC higher than AVC SET,down the torch,the actual AVC lower than AVC SET,up the torch.
i think,change the software is not the best way.
u can do it yourself.
thanks
