Abstract
The present invention is directed to a method and apparatus of controlling the welding output of a welding power source by incorporating an open condition detect circuit. An output feedback circuit provides feedback to a controller such that the controller may regulate the output of the welding source of power. As such, the controller prevents a welding output until an open condition followed by a short condition at the welding area is detected.
