Abstract
Methods and systems for clearing short circuits during a MIG welding process are disclosed. A method may include detecting a short circuit and increasing output current of a power source at a first ramp rate to clear the short circuit. The method further includes increasing output current at a second ramp rate after the output current reaches a threshold. Power sources and systems implementing the method are also provided.
