FIELD: process engineering.
SUBSTANCE: plasma cutting unit comprises plasma jet source and plasma torch with electrode and jet with minor electrode gap at plasma jet bottom end to make a plasma chamber there between. Current I created by plasma jet source 1 and fed through plasma torch 4 for at least 1 second to mean arithmetic magnitude set for plasma cutting is subjected to oscillation about sad mean magnitude for generation of pulsations of frequency f of 0.1-500 Hz.
EFFECT: longer life of electrode.
