[TheForge] Gas saver

[Dan Brewer]

You turn off the acetylene first.  With the o2 still running there is no
possibility of the flame retreating into the torch.  Please reread your
safety chapter for gas welding.

#

Follow these procedures with oxygen cylinders and torches:
# Slowly open the oxygen cylinder valve all the way.
# Open the oxygen torch valve l/2 turn.
# Use the gas regulator crew to adjust the oxygen to working pressure.
# Turn off the oxygen torch valve.

To light the torch:
# Reopen the acetylene torch valve 1/4 turn and light the gas with a
friction lighter. Never use matches.
# Open the oxygen valve 1/4 turn and adjust the flame.

To shut off the torch:
# Close the torch valves--acetylene first, then the oxygen.
# Close the cylinder valves again--acetylene first, then the oxygen.
# Open both torch valves to release the pressure.
# Shut off the regulator adjusting handle until you can no longer feel any
spring tension.
# Close the torch valves.

These procedures reduce the chance of leaks and possible fire.

Leave the valve wrench on the acetylene cylinder whenever the valves are
open; this permits an emergency shut-off of the gas.

Do not leave pressure in the hoses. If you must leave the area, shut off the
oxygen and acetylene at the cylinder.

The O2  should be turned off first or the possibility of  flash back may 
occur.
Although with flash suppressors standard now I guess this is not a problem.
 
 A one way valve attachment is the deal I am trying to attach a word to.
The flash suppressor is what was on the barrel of my M-16.
