Abstract
A method includes supplying a welding current to a welding zone, monitoring, during a welding current ramp down period of a given short arc welding process cycle, a voltage across a current braking switch that is in an open state and that causes a decrease in welding current being supplied to a welding zone; and when the voltage across the current braking switch that is in the open state reaches a first predetermined voltage threshold, closing the current braking switch before a completion of the welding current ramp down period of the given short arc welding process cycle.
