What to do if the plasma cutting machine air pressure is too low?
When the plasma cutting machine is working, such as the operating pressure is far lower than the air pressure required by the specification, which means that the plasma arc spewing out speed is weakened, the input air flow is less than the specified value, at this time can not form a high-energy, high-speed plasma arc, resulting in poor incision quality, cut through, incision tumor phenomenon. The reasons for the shortage of air pressure are: air compressor input air is insufficient, cutting machine air conditioning valve pressure is too low, the solenoid valve has oil pollution, air route is not smooth and so on.
The solution is to observe the air compressor output pressure display before use, if the requirements are not met, the pressure can be adjusted or the air compressor can be repaired. If the input air pressure has reached the requirements, should check that the air filter pressure relief valve is adjusted correctly, the gauge pressure shows whether the cutting requirements can be met. Otherwise, the air filter pressure relief valve should be daily maintenance, to ensure that the input air is dry, oil-free.
If the input air quality is poor, will cause oil to produce in the solenoid valve, valve core opening difficult, the valve port can not be fully opened. In addition, the torch nozzle pressure is too low, also need to replace the solenoid valve, the gas section will also cause the air pressure is too low, according to the CNC plasma cutting machine specification requirements to replace the trachea.
