A plasma cutting device with pneumatic striking is at least provided with a cylinder (4) for a pneumatic piston (5) fit to move an electrode (2) inside a nozzle (3), for the plasma exit, between a rest condition (R) and an operational condition (O) in which the electrode (2) and the nozzle (3) are respectively in mutual contact and spaced apart. The piston (5) is connected at a short distance from the free end to the electrode (2). Said distance is shorter than the half of the maximum longitudinal dimension of the device (1). |
