4 Shutting off blowpipe
5 CLOSING DOWN
12 Once all leaks have been corrected,
re-open cylinder valve slowly.
13 Repeat the procedure (steps 9 tp 12)
for the fuel gas.
14 If the valve is not handwheel operated,
leave the cylinder key in the fuel gas cylinder
valve.
1 Open, then close, each blowpipe valve
and oxygen control valve on the cutting
attachment in turn for 2 seconds for every 5
meters of hose.
1 Open the blowpipe fuel gas about
1/4
turn.
2 Light the gas at the tip or nozzle using
only flint type lighter supplied.
3 Increase the fuel gas flow until the flame
no longer produces soot.
4 Open the cutting attachment oxygen
heating control valve, and adjust until a
neutral flame is obtained with the cutting
leaver depressed.
5 Check the regulator set pressures and
readjust if necessary.
1 Close blowpipe fuel gas valve.
2 Close blowpipe oxygen control valve. If
cutting attachment is connected depress
oxygen cutting leaver then close oxygen
heating valve on cutting attachment
3 IN CASE OF SUSTAINED BACKFIRE, CLOSE
IMMEDIATELY BLOWPIPE OXYGEN VALVE
FIRST
1 Shut off blowpipe as in 4.1, 4.2 above.
2 Close both cylinder valves.
3 Open the blowpipe oxygen control valve
to allow the gas to drain out. If using cutting
attachment, then open the oxygen heating
control valve and depress cutting leaver.
4 Unscrew the oxygen regulator control
knob once the contents pressure gauge
reads zero.
5 Repeat the procedure (5.1 - 5.4) for the
fuel gas valve and regulator.
This will allow quick shut-down in an
emergency.
Make certain that no source of ignition is
nearby. Purging will eliminate mixed gases in
hose - a cause of flashback at lighting up.
Set the pressure recommended by the
manufacture
This cuts off fuel supply to the flame.
This procedure is satisfactory for temporary
halts not involving leaving the equipment
unattended.
This cuts off oxygen supply to the internal
flame and should extinguish it immediately.
This procedure should be performed
whenever the equipment is left unattended
or whenever cylinders are being changed.
This will release all pressure in the regulator,
hose and blowpipe.
