union. Displays bottle pressure and working pressure for Oxygen gas. This type of regulator is
intended to control the flow of oxygen gas in an oxyacetylene gas welding & cutting set-up and

should be fully trained in all aspects of gas welding and cutting including setting up, operation and
safety procedures.

including hands and tools, must be free from oil or grease.
Function of the regulator. Fitted to the outlet of the gas cylinder valve, the pressure
3.1
regulator reduces the pressure of the gas from cylinder pressure to the constant lower
pressure required for the operation of the equipment. Pressure reduction within the regulator
occurs in a single stage .
3.2. Preparing the cylinder. Make sure that the cylinder to be used is safe and properly secured as
noted in the safety precautions.
3.2.1 Whilst standing to one side ‘crack’ the cylinder valve. ‘Cracking’ is to quickly open and
close the valve allowing gas to escape and clear the valve of any foreign bodies.
WARNING! If grease or oil is found, cease use of cylinder immediately and contact your gas supplier.
