Plasma cutting machine can cut all kinds of metals that are difficult to cut by oxygen cutting with different working gases, especially for non-ferrous metals (stainless steel, carbon steel, aluminum, copper, titanium, nickel) cutting effect is better;
its main advantage is that the cutting thickness is not for large metals, 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 been developed to the present, and the working gas that can be used (working gas is the conductive medium of the plasma arc and the heat carrier, and the molten metal in the incision must be excluded at the same time) has great influence on the cutting characteristics, cutting quality and speed of the plasma arc. have a noticeable effect. 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 various industries such as automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, construction machinery, and steel structures.
The essence of the working process of plasma equipment: an arc is generated between the nozzle (anode) and the electrode (cathode) inside the gun, so that the moisture in between is ionized, so as to achieve the state of plasma. At this time, the ionized steam is ejected out of the nozzle in the form of a plasma jet by the pressure generated inside, and its temperature is about 8 000°С. In this way, non-combustible materials can be cut, welded, welded and other forms of heat treatment processed.
