Abstract
A welding-type system includes a welding-type power supply configured to generate output power for an arc welding process and a controller. The controller calculates a representative duration of a plurality of short circuit events and/or arc events during the arc welding process. Each short circuit event and/or arc event comprises a transitional phase, an intermediate phase, and an end phase. The controller calculates a sum of a duration of the transitional phase, a duration of the intermediate phase, and a duration of a ramp down time from a target current of the intermediate phase to a target current of the end phase associated with a given short circuit or arc event. The controller controls the welding-type power supply to adjust a duration of the transitional phase, the intermediate phase or the ramp down time associated with the given short circuit event such that the sum is within the threshold range of the representative duration. Additionally or alternatively, the controller maintain a duration of the end phase less than a predetermined value.
