The air pressure regulator is a device for controlling the gas pressure that is removed from a bottle. For bottle regulators, they are used to reduce the pressure prevailing in the gas cylinder to an appropriate level that corresponds to the pressure level of the tool. Bottle regulators are often used not only in welding, but also for devices powered by gas cylinders, such as household stoves and various types of gas burners.
