Abstract
Apparatus and methods are provided for a welding-type power system that includes an engine configured to drive an electric generator to provide power to a power output, wherein a power signal is applied to the power output. A sensor monitors the power signal, and a controller determines a change in the power signal based on a feedback signal received from the sensor, and controls the engine to start or stop operation in response to the change in the power signal.
