How to adjust the air pressure of Pneumatic marking machine?

Pneumatic marking machine needs to connect with an air compressor, which provides the main power source of compressed air. Pneumatic marking machine uses the action of air pressure to produce physical force on the surface of the parts, thereby forming marks of different depths. To adjust the depth of the marking effect, you can adjust the value of the air pressure to achieve the purpose.

There is a special air pressure valve on the pneumatic marking machine, and the air pressure can be adjusted by a simple rotation. If a smaller air pressure value is required, the air pressure valve can be rotated counterclockwise, and the value of the air pressure gauge changes at the same time. Similarly, turn the air pressure valve clockwise to adjust to a higher pressure.
