Compared with CNC flame cutting, the history of plasma cutting technology is not long, but due to its good cutting quality and cutting efficiency, the overall development speed is very fast, especially in the non-ferrous metal and sheet cutting, its relative flame cutting The advantage is even more obvious. In use, the CNC Plasma Cutting Machine needs to use the plasma power source as the plasma arc generator. At present, most plasma power sources use high-frequency arc-ignition devices to ignite the arc, and the secondary side voltage of the high-frequency transformer is as high as 3000-6000V. The pulse frequency is hundreds of kilohertz, and the radiation interference and interference to the power grid are very strong. There are also high-current AC-DC contactors and various relays that turn off the grid and cause surge impact. Cnc Plasma Cutting Machine manufacturers
In view of this, the plasma cutting method requires high anti-interference ability to the computer control system, that is, it can resist the interference of the plasma arc striking, and the interference of other equipment to him, otherwise the system will not work normally, even for the numerical control The system causes damage and affects the service life of the system. In the design of the system, Blol Intelligent comprehensively considers various possible interferences and takes corresponding measures to eliminate or reduce interference to ensure the normal use of the machine and the full performance. At the same time, in order to suppress the interference of the plasma generating power supply and reduce the pollution to the power grid, the technical department also proposes the following suggestions for the user's on-site operation flow for reference: 1. Add a shield to the high frequency arc starter to reduce high frequency radiation; 2. Modify the control circuit of the plasma power supply; 3. Other anti-interference measures.
