The failure of cutting carbon steel impervious by CNC plasma cutting machine is generally due to the deviation of the machine plasma power supply equipped with CNC plasma cutting machine, so we can start from this aspect first.

First, check the size of the cutting current set by the plasma power supply at this time (the so-called cutting current of the plasma power supply is used to measure the plasma cutting ability, that is, the cutting thickness. Generally, the machine plasma power supply has a rotating button of the cutting current, which can be set according to the actual thickness of the cutting plate). If the plate is too late, This happens when the cutting current is set too low; At this time, the problem can be solved by adjusting the cutting current and iCNCreasing it appropriately.

This phenomenon can also be caused by the power supply itself. The obvious problem is the plasma serial rate. Imported plasma (the temporary load rate of ordinary inverter plasma power supply is about 80%) is good, and the serial load rate of domestic plasma is very low. It's OK to cool down and rest after using it for a period of time. At present, the commonly used power sources with good quality iCNClude domestic Chengdu Huayuan, American feimat, Hypertherm, Taiwan plasma, etc

Detailed reasons; The cutting torch pipeline is blocked, and some oil has stuck to the pipeline. It seems that the air pressure is sufficient, but the air pressure sprayed from the gun head is not enough. It is recommended to replace the plasma cutting head. Perhaps the plasma cutting torch takes too long and is aging. It is recommended to replace it. Check whether the arcing test can penetrate after the initial positioning under the test. If it can, it means that the initial positioning value may be set high. If it can't check other problems; You can find out the reason according to the error prompt displayed on the control board of CNC plasma cutting machine, or consult the manufacturer of plasma power supply.
