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.
