ABSTRACT:
A method and system for remotely controlling operational parameters of welders by communicating over a welding cable thereof with a remote device electrically coupleable between a workpiece and an electrode holder of the welder. The operational parameters include remotely enabling and disabling the welder, remotely choking the engine thereof, remotely controlling coarse and fine current adjustment, and remotely controlling other parameters otherwise controllable from a control panel of the welder. The remote device having one or more operational parameter signal circuits electrically coupleable between the workpiece and the electrode holder for producing unique operational signals on the welding cable, a sensor circuit that detects the operational signals and produces corresponding operational sense signal in response thereto, and an operational control circuit that actuates operation controls corresponding to the operational parameters on the control panel of the welder in response to the operational sense signals.
