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.
