摘要： A control interface for a welding device facilitates selection of a welding process and of the various operating parameters associated with the welding process. The control interface includes a process selector to select one of a plurality of welding processes, such as AC TIG or DC STICK, and a plurality of parameter selectors for selecting operating parameters associated with the welding process, each parameter selector having a plurality of settings. Selection of the various parameter settings is constrained by a controller which recalls from memory the parameter settings associated with the selected welding process, and which may further enable, disable or default to particular settings based on the selected welding process or the selection of other settings.

摘要： An apparatus for initiating a welding arc during a lift arc start. The apparatus includes a power circuit to provide welding power to a power output, a background circuit to provide background power to the power output to maintain the welding arc during low power welding processes, and a controller. The background circuit is enabled prior to drawing the welding arc, thus providing a background voltage to the power output of the welding device. The background voltage is monitored such that the controller can detect when the welder has touched the electrode to the workpiece. Upon detection of a short, the controller enables the power circuit to provide a flow of output current to the power output.
