The invention relates to an inductive thermal plasma torch comprising a confinement tube that comprises, longitudinally in relation to the tube, metal fingers which are insulated from each other, an ignition device that comprises an igniter () and an igniter support (), the purpose of the igniter () being to initiate a discharge in the plasma of the torch, the support having an electrically conductive end () which is connected to the electrical earth () of the plant and another, electrically insulating, end () which carries the igniter, the ignition device also comprising an electrically conductive connection () connecting the igniter () to the electrically conductive end () of the support so that the igniter is able to initiate the discharge in the plasma, the electrically conductive connection () having a section that is sufficiently narrow to limit the intensity of the current capable of passing through the igniter () in order to avoid electrical arcing by capacitive discharge between the ignition device and another part of the torch.
