The plasma cutting machine uses different working gases to cut various metals, especially for non-ferrous metals (aluminum, copper, titanium, nickel), the cutting effect is better; its main advantage is that the plasma cutting speed is fast when cutting metals with small thickness , Especially when cutting ordinary carbon steel sheets, the speed can reach 5-6 times that of ordinary cutting machines, the cutting surface is smooth, the thermal deformation is small, and there is almost no heat-affected zone.
Plasma cutting machine, the available working gas (working gas is the conductive medium of the plasma arc, it is also the heat-carrying body, and at the same time the molten metal in the incision must be removed) has obvious effects on the cutting characteristics, cutting quality and speed of the plasma arc. influences. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases.
Plasma cutting machines are widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, steel structures and other industries.
Obtaining plasma from water vapor 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 0.3mm or more.
