System and Method For Providing Welding Type Power on Multiple Outputs

Abstract:

A method and apparatus for providing welding type power on one of at least two output terminals is disclosed. Input power is received and welding type power is derived and provided by a shared power circuit. The welding type power is provided across a shared terminal and only two process terminals in response to a desired process. The desired process can be set by user input, feedback, or sensing working connections. The process terminal is selected by selectively opening and closing at least two controllable switches.
