Abstract

A wireless voice recognition control system for controlling the operation of an electric welder power supply by operator voice commands is disclosed. The system includes a remote module carried by the welder and a host module interfaced with the electric welder power supply. The remote module compares voice commands by the welder to preprogrammed voice command templates and operates to generate and broadcast a wireless signal when a spoken voice command matches a voice command template. The host module operates to receive the wireless signal and is configure to operate the electric welder power supply accordingly. In other embodiments, the host module and remote module operate to provide an audible feedback or acknowledgement to the welder. Other embodiments are also disclosed.

Claims
