Plasma cutting machine arc stability directly affects the cutting quality. Plasma arc instability will lead to cuts uneven buildup and other defects. Can also result in reduced lifetime of the device related to the control system, the nozzle, the frequent replacement of the electrode. For this phenomenon, analyze and propose solutions.
Pressure is too low
Plasma cutting machine at work. Such as work pressure is far below the required manual pressure. This means that the speed of the plasma arc discharge decreased. Enter the air flow is less than the specified value. At this point can not form a high-energy, high-speed plasma arc. Resulting in poor cut quality, cut through, cut buildup phenomenon. The reason there is insufficient pressure: less air compressor input. Cutter low air pressure regulator valve. Solenoid valve with oil, gas path is not smooth and so on. Solution yes. Before using the compressor output pressure display to observe. If you do not meet the requirements, adjust or repair the compressor pressure. If the input air pressure has reached the requirements, you should check the air filter regulator adjusted correctly. Cutting gauge display can meet the requirements. Otherwise deal with the air filter regulator for routine maintenance. Be sure to enter the air dry and free of grease. If you enter the poor air quality. Solenoid valve will cause the oil produced. Valve open difficulties, the valve port can not be fully opened. In addition, the torch nozzle pressure is too low. Need to replace the solenoid valve. Road section of smaller gas pressure is too low will cause. Specification requirements may replace the trachea.
