We need to subdivide: the input air of the air compressor is insufficient, the pressure of the air regulating valve of the laser cutting machine is too low, there is oil in the solenoid valve, and the air path is blocked; If the air pressure is too high, it may be because the air filter pressure reducing valve fails.

Therefore, we adopted the following methods for analysis and solution:

1. If the input air pressure has reached the requirements, check whether the adjustment of the air filter pressure reducing valve is correct; The gauge pressure display can meet the cutting requirements.

2. Before use, pay attention to the output pressure display of the air compressor. If it does not meet the requirements, adjust the pressure or repair the air compressor.

3. If the quality of the input air is poor, it will cause oil contamination in the pressure reducing valve, make it difficult to open the valve core, and the valve port cannot be fully opened.

4. The air pressure of the cutting torch nozzle is too low, and the pressure reducing valve needs to be replaced; The smaller section of the air circuit will also cause low air pressure, so the air pipe can be replaced according to the instructions.

5. If there is no problem with the above external air circuit, consider the internal factors of the laser cutting machine. First check whether the air pipe is damaged, knotted, and the connector leaks. If so, replace the pipe.

6. Next, check whether the solenoid valve, one-way valve and proportional valve in the laser cutting machine are damaged. If they are damaged, replace them in time to solve the problem.
