The invention relates to a method for the connection of several current sources, in particular several welding devices (1; 27; 28), plasma jet sources or similar. In independent individual operation a process control and/or regulation device (4; 31; 32) in each welding device (1; 27; 28) transmits set values to a U/I controller for a power component (3; 29; 30). The power component (3; 29; 30) supplies a user, connected to output sockets (38, 39; 40, 41; 42, 43), with energy corresponding to the set values. According to the invention, several welding devices (1, 27, 28) of the same and/or different output, or similar and/or different machine ratings are connected together on the secondary side, by means of the output sockets (38 to 43) to give a welding device (1, 27, 28) with physically greater output. In order to control the connected welding devices (1, 27, 28), the above are connected to each other by means of a proprietary digital interface (44, 45, 46) and/or a particular digital connection interface (47, 48, 49) for a data exchange therebetween. A process control and/or regulation device (4, 32, 33) for a welding device (1, 27, 28) assumes process control for all further connected welding devices (1; 27; 28). |
