The invention concerns method and a system for plasma arc cutting of a workpiece with automatic adaptation of the plasma jet characteristics by simultaneous and practically real-time correction of several parameters, in particular in the complex portions of the cutting path. The inventive method can be used for cutting out more or less complex shapes involving sharp changes of direction in the cutting path, for example when producing an acute angle or a pointed profile, or patterns of small dimensions or complex shapes forming recesses in the steel plate. The invention consists in modulating the plasma jet heat energy and kinetic energy, and the plasma arc voltage (U).
