3.2.1.
function of the regulator.
Fitted to the outlets of the gas cylinder valves, the pressure regulator reduces the pressure of the gas from cylinder pressure to the
constant lower pressure required for the operation of the equipment. The left hand gauge indicates the pressure in the cylinder.
The right hand gauge indicates the pressure of the gas being delivered to the torch. Pressure reduction within the regulator occurs in
two stages.
3.2.2.
Use only oxygen regulators to control the oxygen supply. Switching regulators from non-oxygen to oxygen use can introduce
contaminants to the system. ensure that the valve is always clean and completely free of grease or oil. Use a dry lint free cloth
to thoroughly clean the regulator before use. never use an oxygen regulator for other gases.
3.2.3.
Attach oxygen regulator to the appropriate cylinder and ensure the inlet filter is in place and is not blocked or contaminated.
do not use any form of jointing paste or tape between regulator and cylinder valve.
3.2.4.
Before attaching the regulator, wipe the fittings with a clean dry lint free cloth. Screw the union at the base of the regulator to the
appropriate cylinder by hand. ensure that the regulator is correctly orientated so as to be seen properly by the operator in use.
3.2.5.
To tighten, turn

for
oxygen
. A wrench should be used to ensure tight connections.
3.2.6.
Before opening the cylinder valve, ensure that the oxygen regulator’s pressure adjusting screw is released. To do this, rotate the adjusting
screw fully counter clockwise. If this is not done, pressure from the cylinder can damage the diaphragm and render the regulator
inoperative.
3.2.7.
Cylinder valve-to-regulator connections should be checked for leaks using an approved leak detection spray or soap and water solution.
3.2.8. Stand to one side while opening the oxygen cylinder valve. open the valve as slowly as possible until the high pressure gauge reaches
cylinder pressure. ensure you open the cylinder valve slowly as surges of high pressure can cause a blow out.

Connect the
Blue, oxygen
flash arrestor to the outlet on the

regulator.
3.3.2.
Tighten all nuts securely with a wrench. If any sign of oil or grease is found on the flash arrestor or regulator discontinue use
immediately.
note: new hoses contain a preservative powder which must be blown out before use.
3.3.3.
Prior to attaching the torch, blow out both hoses to eliminate any particles or debris. Perform this on one hose at a time and in a well
ventilated area, otherwise you may create conditions for fire or explosion.
a.
Turn the oxygen regulator adjusting screw clockwise to allow 5psi to pass through hose.
b.
Allow oxygen to flow for approximately 10 seconds to purge each hose in turn.
