Abstract
Provided is a system for providing pulsed arc starting phase, where the system comprises power conversion circuitry configured to convert input power to welding-type power and output the welding-type power, and control circuitry configured to control the power conversion circuitry to output the welding-type power. The control circuitry is configured to control the power conversion circuitry to output a plurality of welding current pulses during at least a portion of one or both of a run-in period or a ramp period for wire feeding of a welding wire ends, where each of the plurality of welding current pulses is associated with a respective pulse period and a respective pulse duty cycle.
