Abstract (en)

[origin: US4567346A] The invention relates in particular to plasma cutting. The nozzle (5) is freely slidably mounted in the torch body so as to come into contact with the electrode if the torch is applied against the work piece (16). By disengaging the torch, an arc is struck between the electrode and the nozzle and then transferred to the work piece. Application in particular to low-power plasma torches.
