Abstract: Systems and methods for operating a welding power supply are disclosed. A method may include operating the welding power supply during a short arc welding process having repetitive cycles each including a short circuit phase and an arc phase, during the short circuit phase, causing a fast ramp up of current from a background current level to a predetermined current level, and upon reaching the predetermined current level, slowing the fast ramp up of the current to a relatively slower ramp up of current until the arc phase begins, wherein the predetermined current level is set based on a percentage of a current level detected at a transition between the short circuit phase and the arc phase in at least one prior cycle.

Abstract: Various embodiments may be generally directed to a welding system that monitors an output of the welding system to determine if an output arc should be extinguished or maintained. The welding system can compare an arc voltage output to a voltage threshold and a temporal threshold. When the arc voltage output exceeds the voltage threshold in an uninterrupted manner for the duration of the temporal threshold, an output weld current can be stopped. In turn, the output arc can be broken or extinguished. After a predetermined amount of time, the power source can be re-engaged to prepare for re-ignition of another arc. By tracking the amount of time the arc voltage output exceeds the predetermined threshold, a probability of unwanted arc outs can be reduced or minimized while still providing quick and reliable arc breaking when desired.

Abstract: An arc welding system includes a temperature determination module and a parameter optimization module. The temperature determination module is configured to determine, from among a plurality of possible temperature categories, a temperature category of an electrode during an interruption to an arc welding process on a workpiece based on a comparison of information indicative of a duration of the interruption to one or more timing thresholds. An electric arc between the electrode and the workpiece is extinguished during the interruption. The parameter optimization module is configured to set one or more current parameters of an output current to be applied to the arc welding process when the arc welding process restarts. The current parameters are based on the temperature category of the electrode determined by the temperature determination module.

Abstract: Various embodiments may be generally directed to a welding system that can adjust parameters of a welding process that is restarted after an interruption. The adjusted parameters can account for the temperature of an electrode, parent material, and/or weld pool which may change during the interruption. The adjusted parameters can be optimized based on these temperatures to enhance the quality and reliability of the weld as it restarts.
