FIELD: plasma cutting of metals. SUBSTANCE: method, comprising steps of heating a metal to be cut by an electric arc, had been stabilized by a flow of plasma generating gas, such as air, being passed through a jet of a plasmatron, also includes steps of simultaneous feeding of water-air mixture to a boundary layer of the stream, being emitted from the jet; performing dispersed water feed with the aid of double-phase gas-water stream and dissolving in water compounds of easily ionizable chemical elements. EFFECT: enhanced efficiency of cutting metals. 2 cl, 2 dwg
