Abstract:
A welding machine comprising:a first power source;a second power source;a first welding output;a second welding output;a linking circuit, disposed to selectively connect the first and second power sources in an independent mode such that the first power source is connected to the first welding output, and the second power source is connected to the second welding output, whereby the first welding output is independent of the second welding output, and further to selectively connect the first and second power sources in a combined mode such that the first power source output and the second power source output are connected in parallel and connected to the first welding output, whereby the outputs of the first power source and second power source are combined; anda controller, connected to the linking circuit, wherein the controller includes a mode selector to allow the user to select between the independent mode and the combined mode, and wherein the controller further includes a master output magnitude selector, which is a single selector, that controls the magnitude of the output of both the first power source and the second power source when the user has selected the combined mode.
