A method of controlling a power source includes providing a power supply module. The power supply module includes a first circuit that has at least one first switch. The first circuit is configured to provide a welding current to an electrode of a welding system. The power supply module also has a second circuit that includes a load that is operatively connected to at least one second switch. The second circuit is configured to provide the welding current to the electrode through the load. The method also includes controlling the at least one first switch such that the welding current flows through the at least one first switch and to the electrode during a ramp up portion of a welding waveform and such that no current flows through the at least one first switch during a ramp down portion of the welding waveform. The method further includes controlling the at least one second switch such that the welding current flows through the load and to the electrode during the ramp down portion of the welding waveform. The ramp down portion takes the welding current to a predetermined value.
