2. introDuction
twin gauge regulator to BS EN 2503,2009 complete with bull nose adaptor and 3/8" BSP hose union. Displays bottle pressure and working
pressure for Acetylene gas. This type of regulator is intended to control the flow of acetylene gas in an oxyacetylene gas welding & cutting set-
up and should be used for no other purpose and with no other gas. The person using this regulator should be fully trained in all aspects of gas
welding and cutting including setting up, operation and safety procedures.
3. Set up
NOTE: PRESSURE REGULATORS SHOULD BE TREATED AS PRECISION INSTRUMENTS AND SHOULD NOT BE JARRED OR
KNOCKED.
Warning! Danger of eXploSion. All parts which come into contact with acetylene, including hands and tools, must be free from
‰
oil or grease.
3.1. function of the regulator.
3.1.1. Fitted to the outlet of the gas cylinder valve, the pressure 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.
3.2.1. Make sure that the cylinder to be used is safe and properly secured as noted in the safety precautions.
3.2.2. 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.
‰
3.3. attaching the regulator.
3.3.1. Ensure the inlet filter is in place and is not blocked or contaminated.
If an '0' ring is fitted to the inlet, check for damage and replace if necessary with an '0' ring recommended by the regulator
manufacturer. Do not use any form of jointing paste or tape between regulator and cylinder valve. Before attaching the regulator wipe
the fitting with a clean dry cloth. Screw the union at the base of the regulator to the cylinder by hand. Ensure that the gauges are
correctly orientated so as to be seen properly by the operator. The regulator to cylinder fitting has a reverse left handed thread. To
tighten turn anticlockwise. A wrench should be used to ensure tight connections.
