CNC plasma cutting machine with different working gases can cut various metals that are difficult to cut with oxygen cutting, especially for non-ferrous metals (aluminum, copper, titanium, nickel) with better cutting effects; its main advantage is the ability to cut metals with small thicknesses. When cutting, plasma cutting speed is fast, especially when cutting ordinary carbon steel thin plates, the speed can reach 5 to 6 times that of oxygen cutting. The cutting surface is smooth, the thermal deformation is small, and there is almost no heat affected zone.

CNC plasma cutting machine, the working gas that can be used (the working gas is the conductive medium of the plasma arc and a heat carrier, and also excludes the molten metal in the incision) has a significant impact on the cutting characteristics, cutting quality and speed of the plasma arc. Impact. Commonly used plasma arc working gases include argon, hydrogen, nitrogen, oxygen, air, water vapor and certain mixed gases.

CNC plasma cutting machines are widely used in various industries such as automobiles, motorcycles, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, and steel structures.

By obtaining plasma from water vapor, this is a safe, simple, effective, multi-functional and environmentally friendly method for thermal processing (cutting, welding, brazing, quenching, spraying, etc.) of metals with a thickness of more than 0.3mm. It is truly the first of its kind in the history of the processing industry.

CNC plasma cutting machine consists of plasma gun and chassis. The essence of the working process of plasma equipment is this: an arc is generated between the nozzle (anode) and the electrode (cathode) inside the gun, which ionizes the moisture between them, thereby reaching the plasma state. At this time, the ionized vapor is ejected from the nozzle in the form of a plasma beam due to the pressure generated internally, and its temperature is about 8000°C. This is used to perform cutting, welding, welding and other forms of heat treatment on non-combustible materials.
