What is the plasma cutting arc? What is the difference between its characteristics and the laser cutting machine? Changzhou Maiqiwei CNC Technology Co., Ltd. will introduce the characteristics of plasma cutting arc to everyone. Plasma cutting machine is also called plasma power supply. Plasma cutting machine is a machine that uses plasma cutting technology to process metal materials.

　　Plasma cutting is a processing method that uses the heat of a high-temperature plasma arc to locally melt (and evaporate) the metal part at the incision of the workpiece, and use the momentum of the high-speed plasma to remove the molten metal to form an incision. The plasma cutting machine with different working gases 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 that the thickness of the metal is not large. 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, and the available working gas (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 excluded). The cutting characteristics, cutting quality and speed of the plasma arc are all There are obvious effects.
