Abstract (en)

[origin: WO2007129194A2] A plasma cutting device with pneumatic contact striking, supplied of at least an hollow nozzle (3) having a passing hole (4) for the plasma exit obtained from a gas flow that flow into the cavity in which is housed an electrode (2) moved by a translation means between a rest condition (R) and an operational condition (O) in which the electrode (2) and the nozzle (3) are respectively in contact and spaced. The electrode (2) and the nozzle (3) are equipped with stop means respectively first (5) and second (6) spaced to realize the mutual contact between the electrode (2) and the nozzle (3) in the rest condition (R). The electrode (2) and the nozzle (3) are positioned, in the operational condition (O), at a distance (D) from the passing hole (4) equal at least two times the minimal dimension (M) of such passing hole (4).
