<p>A torch (T) for connection to an electric arc welding system having a wire feeder (20), a power source (40) and a weld process controller (42) for the power source. The torch (T) being connected to the front end of a welding gun (G), which gun has a rear end with a first unique component of a connector. The welding system has a second component of the connector matching the first component. The gun has a communication channel extending from the torch to the first component for transmitting data to the welding system through the connector. The torch has a memory (100) with an identification code outputted on the communication channel (60) to the first component and the system has a decoder circuit (130) connected to the second component and responsive to a selected identification code.</p> |
