Abstract:
1. A method to start and use a combination wire feed and energy source system for any of brazing, cladding, building up, filling, and hard-facing overlaying applications, said method comprising: applying a sensing voltage between at least one resistive filler wire and a workpiece via a power source; advancing a distal end of said at least one resistive filler wire toward said workpiece; sensing when said distal end of said at least one resistive filler wire first makes contact with said workpiece; turning off said power source to said at least one resistive filler wire over a defined time interval in response to said sensing; turning on said power source at an end of said defined time interval to apply a flow of heating current through said at least one resistive filler wire; and applying energy from a high intensity energy source to said workpiece to heat said workpiece at least while applying said flow of heating current.
