Abstract
Disclosed welding-type systems include a welding-type power source to generate output power for a periodic welding process that operates in an arc mode, an open circuit mode or a short circuit mode. A wire-feeder advances an electrode wire toward a workpiece. A controller adjusts the current to below a threshold value during the arc mode to result in the open circuit mode prior to occurrence of a short circuit event based on one or more welding process parameters. In some examples, the controller determines the occurrence of the short circuit event based on the one or more welding process parameters, and adjusts the current to rise above a second threshold level to adjust a heat generated in the welding wire in response to the occurrence of the short circuit.
