ABSTRACT:
A resistance welding device having a welding current source, a control and/or regulating device for regulating the welding current, and at least one set of interchangeable welding guns on which welding electrodes are mounted in such fashion that they can be pressed toward one another to hold sheets to be welded between them. The interchangeable welding guns contain a local data storage memory located on the welding guns for storing data specific to the operation of the welding guns, and a data interface which can interact with a second data interface located on the control and/or regulating device. When the set of welding guns in attached to the welding device, the two data interfaces are connected thereby permitting the specific operating data for the welding guns to be transmitted to the program memory of control and/or regulating device. The invention also includes self-programming welding guns capable of automatically programming a control and/or regulating device with the operating parameters necessary to optimally operate the set of welding guns.
