A plasma spraying device includes a torch head which has a plasma channel that extends between a cathode and an anode. The plasma channel is bounded by a plurality of neutrodes which are electrically insulated from each other. A gap extends between the frontmost neutrode and the anode, which gap is divided into at least two sections. There is a radial distance and an axial distance between the two sections. An insulating disk is arranged in each of the two sections.
