Voortman plasma cutting machine
Plasma cutting machines are only used for ferrous (steel, stainless steel, etc.) and non-ferrous metals (brass, copper, aluminium, etc.) with a maximum thickness of 160 mm.
Plasma cutting is faster than laser cutting for medium or thick plates, and is faster than oxyacetylene cutting for thin or medium plates. In general, plasma cutting is suitable for cutting plates of thick metal.
The principle of plasma cutting is relatively close to that of TIG welding: it involves creating an electric arc that ionizes a gas projected through a nozzle between the electrode and the workpiece to be cut. For plasma cutting air, argon, nitrogen, oxygen or hydrogen are generally used. Regardless of the gas used, you will have to replace the nozzle and electrode regularly.
Portable plasma cutting machines are available for spot applications. Because of the heat generated and the fumes from the vaporized metal, plasma cutting can only be carried out in very well ventilated areas or outdoors.
