Abstract

A power source for a welding or cutting system is provided which preferably includes a power switching circuit, a switching cessation detector, and overshoot reducing means. The power switching circuit switches electrical power to provide an electrical power output signal of the power source to an electric arc tool operatively coupled thereto. The switching cessation detector is responsive to the power switching circuit. The cessation detector generates a switching cessation signal responsive to detecting electrical power being supplied to an electric arc tool operatively coupled to the power source when the power switching circuit ceases switching. The overshoot reducing means is responsive to the switching cessation signal and reduces excess current output from the power switching circuit upon resumption of switching. Related methods are also discussed.
