Abstract: A wire-processing device includes a first advancing device, a cutter head, and a second advancing device. The first advancing device pulls the wire out of a wire store and advances according to the desired length of wire to be cut. After the wire is cut through by the cutter head, the wire-ends of the wire-length are processed. The wire-processing device is provided with a device to determine the diameter of the conductor of the wire including an input coupler that generates in the wire a wire signal, and wherein the wire signal can be sensed by an output coupler which generates an input signal which is interpreted by a signal processor, wherein the cutters of the cutter head touch the conductor and change the input signal when cutting into the wire.
