High leakage reactance transformer and high-voltage rectiying circuit are adopted for the major circuit. Plasma cutting voltaic arc is provided.
Integrated circuit is taken as the controlling core of the controlling circuit, and the reliability is high.
The parameters of the striking circuit are accurately set and the success rate of striking is 100%.
Compressing air is taken as the air supply of the cutting. Then, it is economic, high efficiency and simle. Moreover, the cut is narrow, the cutting plane is smooth and there is no welding slap. Therefore, they can be used to rapidly cut various metals.
