The invention describes a nozzle with spark ignition which can be adapted to a torch, comprising a front part and a rear part. The front part comprises spark electrodes adjacent to the proximal end. A high voltage electric current supplied by the electrodes is generated by a piezoelectric element and a percussion member is mounted on the rear part of the nozzle. The front part, after wearing, can be demounted from the rear part in order to be discarded. <IMAGE> |
