Abstract
The measurement of the voltage over the welding point in order to supervise the welding quality takes place by means of voltage taps on the wire electrodes. As a result, the additional parasitic resistances during measurement by means of conventional voltage taps on the roller head or the roller head mounting are completely eliminated, which improves the measuring accuracy.
