IGBT Inverter ARC Plasma Cutter 220V/380V - Upgraded Fans & Circuit from China Suppliers and Factory
Detailed Information
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 (aluminum, copper, titanium, nickel) cutting effect is better; its main advantage is that when cutting metals with small thickness, 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.
Plasma cutting machine, the working gas that can be used (the working gas is the conductive medium of the plasma arc and the heat carrier, and the molten metal in the incision should be excluded at the same time) has obvious effects on the cutting characteristics, cutting quality and speed of the plasma arc. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases.
