Adjusting the pressure and nozzle angle of the blast machine varies slightly depending on the specific blast machine model and manufacturer's guidance, but here are some general steps:
Adjust the pressure:
Determine the pressure required: Different blasting operations require different pressures. For example, removing large areas of rust or paint may require higher pressure, while cleaning more delicate or delicate surfaces may require lower pressure.
In order to adjust the pressure, you need to find the pressure regulating valve, which is usually located at the front or top of the blaster.
Slowly rotate this regulator with each small adjustment, then check the gauge readings.
Perform an actual blast test to ensure that the pressure is appropriate for the job required.
Adjust the nozzle angle:
Determine the desired nozzle angle: The nozzle angle is adjusted based on the shape and size of the object you want to work with, and the effect you want to achieve.
If your blasting machine allows you to adjust the nozzle angle, usually, you just need to manually adjust the nozzle to the angle you need.
After adjusting the nozzle angle, also do an actual blast test to make sure the angle meets your needs.
Whatever you are doing, remember to use appropriate safety equipment such as gloves, goggles, or face shield to ensure safe operation. If you have any questions about how to adjust the pressure or nozzle angle of the blaster, it is recommended to refer to the owner's manual or contact the equipment manufacturer.
