TORCH FOR ELECTRIC ARC WELDING SYSTEM

摘要

A torch for connection to an electric arc welding system having a wire feeder, a power source and a weld process controller for the power source. The torch being connected to the front end of a welding gun, 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 with an identification code outputted on the communication channel to the first component and the system has a decoder circuit connected to the second component and responsive to a selected identification code.

1. A welding apparatus, comprising:
a welding gun having a memory device which stores an identification register which identifies said welding gun; a welding system coupled to said welding gun, said welding system comprising: a waveform generator which creates a welding waveform; a power source which generates a welding output signal based on said welding waveform; and a decoder which is coupled to said memory device in said welding gun;wherein said waveform generator only generates said welding waveform when said decoder detects said identification register of said welding gun.
