Abstract:
A method and apparatus for providing short arc welding-type power is disclosed. The system includes a power supply, a wire feeder, and a controller. The output current is decreased at dive rate when the arc forms. The dive rate is maintained until the currents drops to a threshold, preferably a function of the peak short current in that cycle. Then the current is held steady for a length of time that is a percentage of the short time for that cycle. Then the current is decreased at the normal rate until the short reforms, and the current begins increasing at the normal rate. The holding steady portion can be omitted.
