METHOD AND SYSTEM FOR A REMOTE WIRE FEEDER WHERE STANDBY POWER AND SYSTEM CONTROL ARE PROVIDED VIA WELD CABLES
First Claim
1. A welding system comprising:
- a power source having a primary contactor and a secondary contactor;
a weld cable connecting the power source to a remote device, the remote device operable in a standby mode; and
a controller to regulate activation of the first and the second contactors such that a non-welding voltage is applied from the power source to the remote device across the weld cable when the remote device is in a standby mode.

Abstract
The present invention is directed to a remotely controlled welding machine that uses serializing and modulating circuits to transfer modulated data packets to a welding power source across a weld cable. A transmitter transmits the data packets of desired welding operational parameters to a receiver disposed in the power source across a weld cable also designed to carry welding power from the power source to the wire feeder. The transmitter and other electronics of the wire feeder are constructed to use only a small amount of power which, preferably, is supplied by a DC power supply external to the wire feeder. The DC power supply is designed to provide power to the electronics of the wire feeder when the wire feeder is in a standby mode of operation.

12. A welding system comprising:
-
a power source configured to supply a first power usable during a welding process and supply a second power usable during a standby mode of operation, the second power having a voltage different from a voltage of the first power;
a wire feeder configured to receive the first power from the power source when supplying a consumable electrode to a weld and receive the second power when in the standby mode of operation; and
a welding cable connecting the power source and the wire feeder and configured to carry the first and the second power thereacross. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method of remotely controlling a power source for welding comprising the steps of:
-
packaging feedback of operational commands for a welding-type process into a data packet of encoded data;
transmitting the data packet to a power source from a remote device across a weld cable designed to provide welding power for the welding-type process; and
controlling the power source in accordance with at least data embodied in the data packet. - View Dependent Claims (19, 20, 21, 22, 23)
