1. Power supply for ordinary plasma arc cutting machine. According to different main gases, it is mainly divided into argon plasma arc cutting division, oxygen cutting and plasma arc cutting, and type of air plasma arc. The cutting thickness is generally lower than the current 100A by 30 mm or less. The price is very good, the plasma power supply is cheaper, but the degree of the groove cutting the workpiece, the burr and the dross are a little more.
2. Fine plasma arc cutting. Fine plasma arc current density is high, plasma arc is usually a common multiple of current density, such as rotating magnetic field due to the introduction of technology, arc stability has also improved, so its cutting accuracy is very high.
