How does the Air Plasma Cutting Machine start and cut normally?
In fact, the air plasma cutting machine refers to the plasma machine power that uses the heat of the high-temperature plasma arc to make the metal at the cut of the workpiece form a cutting section. The standard picture of the air plasma cutting machine partially or partially melts (and evaporates), and borrows the momentum of high-speed plasma A processing method that excludes molten metal to form cuts.
The main advantages of air plasma cutting machine in practical work and the cutting range can only be expressed in the following ways:
1.Air plasma cutting machine with different working gas 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 main advantage is that the cutting thickness is not For large metals, the plasma cutting speed is fast, and it is equipped with an arc voltage type automatic height adjustment device, especially when cutting ordinary carbon steel sheets, the speed can reach 5-6 times of the oxygen cutting method (ie, flame cutting method). The face is smooth, the heat distortion is small, and there is almost no heat affected zone.
2. With the development of air plasma cutting machines, the working gas (the working gas is the conductive medium of the plasma arc and the heat carrier, and the molten metal in the cut must also be excluded) cutting characteristics and cutting quality of the plasma arc, Speed has a significant impact. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor, and some mixed gases.
3. Plasma cutting machines are widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, steel structure and other industries!
