Abstract
The disclosure concerns an electrical stud-welding device with a welding head and a stud holder fastened thereto in a detachable manner. The stud-welding device is of the type that can be regulated with respect to various welding parameters, such as charging voltage, capacitance, plunge velocity, weld current, weld time, and plunge damping and providing means for weld studs of different dimensions without the need to perform test welds, thus also allowing automatic change of the stud holder, by designing the stud holder as a data carrier for several specific, variable welding-parameters, and data-acquisition units which can be acted upon by the stud holder arranged on the stud-welding device and a central, device-specific data-processing unit associated with the stud-welding device, and provided for the acquired data, which unit sets the controlled variables in accordance with the data that were determined.
