The invention relates to a method of linking several current sources, in particular several welding devices ( 1; 27; 28 ), plasma current sources or similar. Operating individually and independently of one another, a process control and/or regulating system ( 4; 31; 32 ) in every welding device ( 1; 27; 28 ) transmits desired values to a voltage-to-current controller of a power component ( 3; 29; 30 ). The power component ( 3; 29; 30 ) supplies a consumer connected to output jacks ( 38, 39; 40, 41; 42, 43 ) with power on the basis of the desired values. For the purposes of the invention, several welding devices ( 1, 27, 28 ) of the same and/or a different power rating or having the same and/or different machine specifications, are linked to one another on the secondary-side via the output jacks ( 38 to 43 ) to form a welding device ( 1, 27, 28 ) with a physically higher power output, whereby the interconnected welding devices ( 1, 27, 28 ) are digitally interconnected via a digital interface ( 44, 45, 46 ) which is known per se and/or a special digital connecting interface ( 47, 48, 49 ) for a data exchange. A process control and/or regulating system ( 4, 32, 33 ) of one welding device ( 1, 27, 28 ) assumes process control for all the other connected welding devices ( 1; 27; 28 ).
