摘要： Process and unit for the arc working, particularly plasma cutting, of a workpiece, in which a plasma torch is supplied with an electric current and with a gas mixture containing oxygen and nitrogen, and a plasma jet obtained by the ionization of the gas mixture by the electric current is delivered by means of the plasma torch. The concentration of nitrogen and oxygen in the gas mixture is less than 50%. The gas mixture is obtained by adding a defined amount of nitrogen or, depending on the case, oxygen immediately before the gas mixture is introduced into the torch. The amount of nitrogen or oxygen is defined according to the thickness of the workpiece, to the grade of the constituent material of the workpiece, to the desired work rate and/or to the intensity of the electric current.

摘要： 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).
