A method and apparatus for welding is disclosed. It includes source of power and a controller. An output feedback circuit provides feedback to the controller. The controller includes a comparator that compares the fedback signal to a threshold and/or detects a short on the output. A standby/welding control is responsive to the comparator. Also, an arc end control may be provided that terminates the arc in response to detecting an increase in arc length.
