Several reasons why the plasma electrodes and nozzles of CNC plasma cutting machines are consumed and damaged:
1. Caused by improper use, such as the cutting nozzle is too close to the steel plate when cutting (generally the size of the cutting nozzle is not less than 3-8 mm from the steel plate when cutting with 100A plasma), the external input voltage is too high or unstable, etc.
2. The quality of the electrode nozzle, this is very important, whether the quality of the electrode nozzle you bought passes the test; in addition, there is a problem with the cooperation between the electrode nozzle and the cutting gun. It is possible that the electrode nozzle you are using now is not produced by the same manufacturer. Or the manufacturer of the electrode nozzle and the cutting torch are inconsistent. Although the appearance and size look similar, the size standards of different manufacturers are different, so the electrode nozzle of each manufacturer may not be well matched with the cutting torches of other manufacturers. use, which can easily cause problems.
3. Problems such as the material, thickness, and cutting process arrangement of the workpiece to be cut, the material of the workpiece to be cut, the electrode nozzles consumed by ordinary plate, stainless steel, cast iron and other materials are relatively small, and some metal materials consume more accessories (such as copper, aluminum, etc. ), if you cut a plate with a thickness of about 10mm, it is reasonable to save nozzles. I wonder if there are plates with a thickness of more than 16mm? If you often cut sheets of more than 16mm, it will cost more nozzles.
In addition, if perforation cutting is often required in the process of work, it will cost more than twice as much as the regular edge arc cutting; so everyone must remember to choose the appropriate power size when choosing the plasma power supply and cutting nozzle (generally Plasma power supply with plasma quality and cutting thickness as the standard) and nozzles with corresponding ampere size and caliber size are conducive to the most adequate cutting effect and service life.
