1, The generation and characteristics of the plasma arc

Generally, an arc having an arc density of an arc density (uncompressed) under natural conditions is referred to as a free arc; a conductive arc of a free arc is fully ionized, and an arc temperature is between 6000 ° C and 8000 ° C. Under the action of air pressure, voltage and magnetic field, the columnar free arc (column cross-sectional area is proportional to power) can be compressed into a plasma arc, and the conductive cross section of the plasma arc has small energy concentration. The gas in the arc column can almost reach the ion state. The arc temperature can be as high as 15,000 ° C - 30 000 ° C. It can quickly melt objects such as metals.

2, The principle and application of plasma cutting

Cutting, generally refers to the cutting of metal. Plasma arc cutting is a cutting method that uses a very fine and high temperature plasma arc to rapidly melt a local metal and then blow away the molten metal with a gas stream. Plasma arc cutting has been widely used in various engineering construction and manufacturing industries due to its high cutting efficiency, low loss and wide application range.
