How to Choose a Plasma Cutting Machine?

Plasma cutter is a machine that uses plasma cutting technology to process metal materials. With different working gases, it can cut all kinds of metals that are difficult to cut by oxygen, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel). The opposite of the plasma cutting machine is the flame cutting machine, and the two cutting methods are different. 

Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to partially or partially melt (and evaporate) the metal at the incision of the workpiece, and uses the momentum of the high-speed plasma to remove the molten metal to form an incision. Plasma cutting with different working gases can cut all kinds of metals that are difficult to cut with oxygen, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel). The cutting effect is better; its main advantage is that the thickness of the metal is not large. At this time, plasma cutting speed is fast, especially when cutting ordinary carbon steel sheet, the speed can reach 5-6 times that of oxygen cutting method, the cutting surface is smooth, the thermal deformation is small, and the heat affected zone is less. Plasma cutters are widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, construction machinery, steel structures, ships and other industries. Plasma cutter with different working gas can cut all kinds of metals that are difficult to cut by oxygen, especially for non-ferrous metals (stainless steel, aluminum, copper, titanium, nickel), the cutting effect is better; its main advantage is to cut metals with small thickness When cutting, the plasma cutting speed is fast, especially when cutting ordinary carbon steel sheets, the speed can reach 5-6 times that of the oxygen cutting method, the cutting surface is smooth, the thermal deformation is small, and there is almost no heat-affected zone.

The plasma cutting machine has developed to the present, the available working gas (the working gas is the conductive medium of the plasma arc, it is also the heat carrier, and at the same time the molten metal in the incision must be removed). The cutting characteristics, cutting quality and speed of the plasma arc are all There are obvious effects. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases
