Benefits of technology
Enhances welding productivity and system longevity by reducing cable damage risks, minimizing noise interference, and improving operator convenience and portability by enabling wireless control of multiple welding parameters.
Problems solved by technology
Despite the benefits of such a set-up, there are also numerous drawbacks associated with communication and control of the welding-type system in such a manner.
One drawback to this cable-based control is that the communications cable is typically fragile relative to the welding cables designed to carry high currents at high voltages.
As such, the remote control communications cable can become damaged by being crushed or snagged from contact with surrounding machines and / or traffic.
This can cause damage to the welding-type power source if internal power conductors become shorted to signal leads that are connected to sensitive signal level circuitry and obviously reduce productivity.
One of these concerns is the introduction of high frequency electrical noise to the welding-type system, which occurs because of the high voltages present in the environment surrounding the communications cable.
Because of the numerous drawbacks associated with communication cables for remote control of a welding-type system, attempts have been to modify the manner of communication in newer systems.

Embodiment Construction
[0016]FIG. 1 shows a welding-type system capable of performing various types of operations. FIG. 1 also shows a remote control communication system for controlling a welding-type device. The welding-type system 10 is merely representative of a wide variety of welding-type machines having various sizes, features, and ratings. The welding-type system, as contemplated herein, can be configured to not only perform standard welding type operations such as TIG, MIG, and / or stick welding, but can also be capable of performing various cutting operations that are closely associated with the various welding procedures, such as plasma cutting for example. In the exemplary embodiment of FIG. 1, the welding-type system shown is preferably a tungsten inert gas (TIG) welding system, however, one skilled in the art will readily appreciate that it may be any related welding or cutting system, including those listed above. TIG welding system 10 includes a power source 12 to condition raw power and ge...

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 controller including a control transceiver located on 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.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates generally to welding machines and, more particularly, to a method and apparatus of communicating control signals to a welding power source from a remote location. Specifically, the invention relates to a welding system whose operation is governed by control signals transmitted by a wireless control panel. A plurality of welding parameters in the welding system are set and adjusted in response to wireless command signals received by 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 for welding.[0002]Welding and cutting are essential operations in many different areas of manufacturing and construction in today's economy. The versatility and efficiency of welding and cutting systems is vital to, and allows for, the efficient completion of many complex and dynamic welding operations. In many welding ...
