Plasma arc cutting machine is a machine that USES plasma cutting technology to process metal materials, which used by plasma cutting machine
Is the use of high temperature plasma arc quantity of heat to make the metal parts of the workpiece slit or partial melting (and evaporation), and the plasma momentum ruled out a molten metal to form a kind of processing method of incision.
In addition to the general form, the plasma cutting method is derived in the form of water compression plasma cutting and so on.
The most commonly used methods are plasma cutting and air plasma cutting.
General plasma cutting does not need to protect gas, working gas and cutting gas gush from the same nozzle.
When the arc is used, the small air flow ion gas is used as the ionizing medium;
At the time of cutting, the gas is ejected at the same time to remove the molten metal.
Air plasma cutting generally USES compressed air as ionic gas. This method has low cutting cost and convenient source.
The compressed air is heated, decomposed and ionized in the arc. The generated oxygen cutting metal produces chemical exothermic reaction and speeds up the cutting speed.
Fully ionized air plasma has high enthalpy value, so the energy of arc is large and the cutting speed is fast.
