Cutting workpiece by combustion using fuel and oxygen. Beskrivning The process Combustion gas mixture  is burned at the cutting nozzle with the purpose of heating the material to the ignition temperature. Pure oxygen gas is supplied through the center of the die , which supplies the additional energy needed to carry out the actual cutting. This cutting beam  helps to melt and burn the material, and thus creates a cut in the workpiece . Material residues is pushed away from the section of the oxygen gas in the form of a slag stream . The oxygen purity and outflow rate, which is largely influenced by nozzle design, greatly affects gas cutting results. What fuel gas is chosen depends on several factors such as thickness of the workpiece and the time for heating. Cutting with multiple parallel cutting heads is a common way to increase productivity.
