In general, the uncompressed gas (at atmospheric pressure) in an electric arc is partially ionized. The temperature of the such so-called free-burning electric arc is ranging from 6,000℃ to 8,000℃. When imposed to high pressure, the free-burning electric arc will ionize almost all the gas within it, thereby creating a plasma jet with high velocity, high current density, and a small conductive cross-sectional area. The plasma jet will immediately reach a temperature ranging from 15,000℃ to 30,000℃, quickly melting down the metal processed. With our plasma cutter, the cutting process involves utilizing an extremely sharp and high-temperature plasma arc to quickly pierce through the workpiece and then blow away the molten material.
