Solving the problem of insufficient air pressure in the laser welding machine requires inspection and processing from many aspects. ‌

Check the power supply: ‌First you need to check whether the power supply of the laser welding machine is stable. ‌You can use a voltmeter or power load tester to 

detect voltage fluctuations in the power supply. ‌If the power supply is unstable, ‌you can consider replacing the power supply or using a voltage regulator to ensure

 the stability of the power supply. ‌

Check the power line: If the power supply is stable, but the laser welding machine still has insufficient air pressure, you can check whether the power line is normal. ‌

First check whether the power line is loose or has poor contact. ‌If so, ‌the power line needs to be reconnected or replaced. ‌In addition,‌you can also check the load of 

the power line. If the load is too large,‌you can consider reducing the load or increasing the capacity of the power line. ‌

Check the internal circuit of the laser welding machine: If the power supply and power line are normal, but the laser welding machine still has insufficient air pressure, 

you can consider checking whether the internal circuit of the laser welding machine is normal. ‌First of all, you need to check whether the power input terminal of the

 laser welding machine is loose or has poor contact. ‌If so,‌you need to reconnect or replace the power input terminal. ‌In addition,‌you can also check whether the power 

supply filter capacitor inside the laser welding machine is damaged. ‌If it is damaged,‌the power supply filter capacitor needs to be replaced. ‌

Check the heat dissipation: The laser welding machine will generate a lot of heat during work. If the heat dissipation is poor, the air pressure of the laser welding 

machine will drop. ‌ Therefore, ‌ it is necessary to check the heat dissipation of the laser welding machine, ‌ ensure that the vents of the radiator are clear, and that there

 is no dust or oil on the surface of the radiator. ‌If the heat dissipation is poor, ‌you can consider increasing the number of radiators or using a more efficient radiator. ‌

Check the power module: The power module of the laser welding machine is a key component that provides working voltage. If the power module is damaged or 

aged, it will cause the air pressure of the laser welding machine to drop. ‌Therefore, ‌ it is necessary to check whether the power module of the laser welding machine

 is working properly. ‌ If it is damaged or aged, ‌ the power module needs to be replaced.

To sum up, solving the problem of insufficient air pressure in the laser welding machine requires analysis and processing from many aspects such as power supply, power line, internal circuit of the laser welding machine, heat dissipation and power module
