More Information
Summary:The invention relates to a method of cutting a workpiece (40) by means of a plasma arc (2), wherein a device (1) for cutting a workpiece (40) is provided, a pre gas flow is provided around the electrode (11), subsequently to the pre gas flow, a main gas flow (32) is provided around the electrode (11), wherein the main gas flow (32) comprises an oxidizing gas, a plasma arc (2) is generated between the electrode (11) and the workpiece (40), wherein said workpiece (40) is cut by means of said plasma arc (2), and wherein said pre gas flow comprises an oxidizing gas at a concentration of 50 ppm to 10000 ppm. The invention further relates to a device (1) for cutting a workpiece (40).
