A WELDING-TYPE SYSTEM WITH POWER SOURCE AND REMOTE DEVICE CONNECTED THROUGH A WELD CABLE USING BINARY PHASE SHIFT KEYING FOR TRANSMITTING COMMANDS OVER THE WELD CABLE; A METHOD OF REMOTELY CONTROLLING SUCH POWER SOURCE USING SUCH TRANSMITTING PHASE S

摘要

The present invention is directed to a system (10) and method of remotely controlling a welding machine with command signals transmitted to the welding power source (12) across a weld cable (16,18) connecting the power source (12) to a remote device (14), such a wire feeder (14). A transmitter transmits the control commands containing desired welding operational parameters to a receiver disposed in the power source (12) across a weld cable (16,18) also designed to carry welding power from the power source (12) to the wire feeder (14).
