Abstract
According to an example embodiment, a system controls a resistance-based welding application with certain compensation for adverse aspects attributable to the power for the welding application being from an AC line. The system includes a power metering arrangement adapted to measure a first value of a power-based parameter from the AC line for a condition in which weld power is not commanded, a second value of the power-based parameter from the AC line while weld power is commanded during a first interval, and a third value of the power-based parameter from the AC line while weld power is commanded during a second interval. The system additionally includes a circuit adapted to respond to the first, second and third values by generating an estimated value for the power-based parameter corresponding to the condition in which weld power is not commanded, wherein the resistance welding application is controlled based on the estimated value.
