Gas Mixtures instead of individual gases
Assist gases play an important role in laser cutting. Nitrogen or oxygen not only expel the cut material, but also have a direct influence on the cutting process. Depending on the gas, the cutting speed and quality are different. Both gases have specific advantages but also disadvantages. gas mixture, i.e. the mixture of nitrogen and oxygen, combines the positive properties of the individual gases and thus delivers perfect cutting results. Especially in the medium and thick sheet range, the material can be cut faster and at the same time rendered practically free of oxide and burrs. Any reworking is minimised and your costs are significantly reduced.
