Abstract

A welding system comprises: power conversion circuitry configured to output welding power to a weld circuit; a voltage sensor configured to measure a voltage of the weld circuit; and control circuitry configured to: control the power conversion circuitry to output the welding power according to one or more first welding parameters; monitor the measured voltage during a background phase to determine whether a short circuit event occurred in the weld circuit by detecting that the measured voltage is greater than an anomalous cathode event voltage threshold; in response to determining that the short circuit event occurred, determine one or more second welding parameters based on one or more short circuit parameters of the short circuit event; and control the power conversion circuitry to output the welding power according to one or more second welding parameters.
