[TheForge] Gas-saver problem

[Bruce]

I don't use acetylene and never have.  A good friend does and has a gas
saver, and, as Frosty says, it pops every time he hangs up the torch.

Possible rationale:  Acetylene tanks are of necessity at low pressure.
Oxygen tanks are at high pressure.  Conceivably shutting off the acetylene
first might somehow enable high-pressure oxygen to enter the acetylene line
or regulator - a bad situation.  I can't see how this could happen if all
is working well, but if the gas saver valve were faulty, maybe then?
