A system (100) and method is provided. The system (100) includes a high intensity energy source to create a molten puddle (112) on a surface of a workpiece (115) and a wire feeder (150) that feeds a wire (145) to the molten puddle (112) via a contact tube (122, 125). The system (100) also includes a power supply (130, 135) that outputs a first heating current during a first mode of operation and a second heating current during a second mode of operation. The system (100) further includes a controller (195) that initiates the first mode of operation in the power supply (130, 135) to heat the wire (145) to a desired temperature and switches the power supply (130, 135) from the first mode of operation to the second mode of operation to create a micro-arc. The second mode of operation provides at least one of an increased heat input to the molten puddle (112) and an increased agitation of the molten puddle (112) relative to the first mode of operation. |
