Abstract
A method and apparatus for providing welding-type power includes an input circuit, a switched circuit connected to the input circuit, and an output circuit connected to the switched circuit. A controller controls the system output in response to a setpoint and an output feedback signal. A first gain is used to control the output at start up, and a second gain is used to control the output during steady-state welding. The first gain is greater than the second gain.
