1. Air pressure adjustment

Air pressure is one of the important factors affecting the spraying effect. Appropriate air pressure can ensure that the paint is evenly atomized and effectively covers the sprayed surface.
First, you need to find the air pressure regulating valve on the spray gun and set an initial air pressure value according to your paint type and spraying needs. Generally speaking, it is more common to set the air pressure of low-pressure spray guns in the range of 30-50 PSI (pounds per square inch).
After the initial setting, you can gradually increase or decrease the air pressure and observe the changes in the spraying effect. Each time you adjust, it is recommended to make fine adjustments in units of 5 PSI to find the air pressure value more accurately.
Note: Too high air pressure may cause the paint to be over-atomized and form a granular spraying effect; while too low air pressure may cause the paint to not be fully atomized and form an uneven coating. Therefore, when adjusting the air pressure, it is necessary to make flexible adjustments according to the actual situation.

2. Nozzle adjustment

The adjustment of the nozzle also has an important impact on the spraying effect. By adjusting the flow rate and spray width of the nozzle, you can control the coverage and uniformity of the paint.
1. Find the nozzle adjustment knob, which can control the flow rate and spray width of the paint.
2. Adjust the paint flow rate: By rotating the paint flow adjustment knob, you can increase or decrease the flow rate of the paint. When adjusting, it is recommended to make fine adjustments in a small range to avoid excessive paint flow.
3. Adjust the spray width: The spray width adjustment knob can control the spray range of the paint. By rotating this knob, you can increase or decrease the width of the spray. Similarly, you also need to make fine adjustments in a small range when adjusting.
4. Test the spray effect: After adjusting the nozzle, it is recommended to conduct an actual spray test to observe the changes in the spray effect. You can test under different air pressures and nozzle settings to find the combination of spray parameters.
