Abstract
Systems and methods to start arc welding are disclosed. An example welding-type power supply includes: power conversion circuitry configured to convert input power to welding-type power; and control circuitry configured to: prior to a welding operation, control the power conversion circuitry to stop outputting the welding-type power to a wire electrode; and in response to identifying contact between the wire electrode and a workpiece: control the power conversion circuitry to output an arc starting current to the wire electrode; control a feed motor of a welding torch to retract the wire electrode; control the feed motor to advance the wire electrode based on a first parameter of the welding operation; and control the power conversion circuitry to output the welding-type power to the wire electrode based on the first parameter or a second parameter of the welding operation.
