Method for transmitting data and/or synchronizing at least two welding devices and device therefor
First Claim
1. Method of transmitting data between a welding device and another welding device which comprises controlling a welding process by means of a control system, supplying an arc with energy from a current source and striking the arc between a workpiece and a welding torch, supplying the welding device with power via a supply network, whereby the data is transmitted between the welding devices, transmitting the data, signals and welding parameters or synchronisation signals for one of the welding devices via a first communication unit across the supply network, whereupon the transmitted data, signals and welding parameters or synchronisation signals are read from the supply network by the other welding device and processed by means of a second communication unit and another data exchange is optionally run, and generating a synchronization signal by the one welding device at specific instants of the welding process so that the control system synchronizes control of the welding process on the basis of the synchronization signal.

Abstract
The invention relates to a method of transmitting data between and/or synchronising at least two welding devices (1, 27) or current sources or with another component and another device, which are supplied with energy via a supply network (35), whereby the functions of the welding process are controlled and/or regulated by means of a control system (4, 30) of the welding device (1, 27). The data, signals and welding parameters or synchronisation signals to be transmitted from a welding device (1, 27) or a welding current source or another component and another device, in particular by a processor, a PLC controller, a data module or a computer, etc., are converted by means of a communication unit (36, 37) into a data protocol which is then modulated by a communication unit (36, 37), in particular a modulation module (42, 43), across the supply network (35). The modulated data protocol is demodulated and processed by means of the preferably integrated communication unit (36, 37), in particular by means of a demodulation module (44, 45), of another welding device (1, 27) or a current source or another component or another device, and another data exchange, in particular a two-way data transfer, is optionally run.
