Safe To Use, High Reliability

Composed of an electronic control system and a nozzle, the electric arc generated by the electronic control system is ejected from the nozzle after being compressed by the compressed air, which is similar to the nature of the two-way welding. The compressed arc has a high temperature of 10,000 degrees. In order to cut, it is possible to cut non-ferrous metals such as copper, stainless steel, and aluminum, and the cut is narrow. The temperature of the compressed arc is very high. The arc is blown out in a small hole with compressed air. The arc is ionized air.

Plasma: As the temperature rises, the general substance in turn appears as a solid, a liquid, and a gas. They are collectively called the three states of matter. As the gas temperature rises further, many, even all, of its molecules or atoms will dissociate into electrons and positive ions due to intense mutual collisions. At this point, the material will enter a new state, which is mainly composed of electrons and positive ions (or positively charged cores). The substance in this state is called plasma, which can be called the fourth state of matter.

The high-leakage transformers and secondary-side rectifier-type cutting machines originally used in China have gradually been replaced by inverter plasma cutting power supplies. The principle is shown in Figure 1. Domestic plasma power sources are mostly used for manual cutting and distribution on cart cutting machines. In recent years, due to improvements in performance, the inverter plasma cutting power supply uses advanced IGBT inverter technology. It has the advantages of small size, light weight, low noise, low power consumption, and easy carrying. The operation is simple, the cutting speed is fast, the incision is narrow and smooth, and the workpiece deformation is small. Safe to use, high reliability. With over-voltage, under-voltage, over-current, overheating and other automatic protection. Gradually replace traditional oxyacetylene cutting
