In a method and means for operating an oxygen cutting machine for oxygen cutting of cast strands and workpieces the pressure and flow of the heating gas and heating oxygen are varied during the oxygen cutting process on the cast strand and/or workpiece with the pressure and the quantity of the heating gas and heating oxygen from the beginning to the end of the cutting path being reduced stepwise by at least 25%. During this process a constantly good quality of the cut surface on the workpiece is provided and the quantities of gas required for the oxygen cutting are reduced.
