Abstract: A method and apparatus of communicating control signals to a welding power source from a remote location includes a welding system operated by control signals transmitted by a wireless remote control that can be remotely located from the welding power source. A plurality of welding parameters in the welding system are set and adjusted in response to wireless command signals transmitted to a receiver that is connected to the welding power source via a connection port and is further connected to a controller in the welding power source. In this regard, an operator is able to quickly and efficiently control a welding system from a remote location, with no more cables than are necessary to perform the intended task.

Abstract: A high frequency power source configured to provide a variable voltage output is described such as for use in welding systems. The high frequency power source charges a capacitive storage device. A transformer having a primary winding coupled to the output of the high frequency power source and establishing a resonant frequency signal with the capacitive storage device, and a secondary winding coupled to the welding power supply, superimposes the resonant frequency signals onto the welding power signal of the welding power supply during periods of the resonant rings. By varying the voltage output from the high frequency power source, the high frequency energy delivered to the welding torch can be optimized for a variety of welding applications.

Abstract: A welding device is disclosed having a remote control device configured to control an operating parameter of the welding device (e.g., welding current) and a control circuit to receive a remote device signal from the remote control device and to determine the type of remote control device based on the remote device signal. Remote devices may be "trigger only", "hand control", "fingertip control" or "foot control" devices. The welding device further includes an operating parameter selector (e.g., welding amperage) and a welding process selector (e.g., TIG, STICK) mounted on a control panel. The control circuit receives an operating parameter selector signal from the operating parameter selector and a welding process selector signal from the welding process selector, and controls an operating parameter with one of the remote device signal and the operating parameter selector signal based on the welding process selector signal.

Abstract: 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.
