Abstract: A system, computer-implemented method, and article for controlling a user interface of a portable welding system are described. An input signal receiver, operable on a processor, is configured to receive one or more input signals from one or more input devices. A display controller, operable on the processor, is configured to receive, input information based upon the one or more input signals. A display device is configured to display a user interface provided by the display controller, the user interface including a first portion including an adjustable value and a second portion including a non-adjustable value. The display controller is configured to highlight changes to the non-adjustable value based upon changes made using the one or more input devices to the adjustable value.
