Welding process. During this period, the torch switch is released.
Note: If the output pulse function is turned on, the output current is pulsed. If the output pulse function is
turned off, the output current is DC current;

:
Repress down the Torch switch, the output current slopes down to crater current; if the output pulse
function is turned on, the slope down current is pulsed;
