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.
Electrical stud-welding device for welding studs of different diameters comprising a welding head and a stud holder detachably fastened thereto, means for regulating the stud-welding device with respect to a plurality of welding parameters including studs of different dimensions the stud holder serving as a data carrier and control for such variable welding parameters, data-acquisition units activated by the stud holder and location on a part of the stud-welding device, optionally on its welding head, and a centrally disposed data-processing unit associated with the stud-welding device for sensing stud size diameter, which unit controls the variable parameters in accordance with the predetermined sensed data.
