FYI: There is a heavier walled propane tank, available through your
welding supplier, that is often used by plumbers who have to haul
them in and out of all kinds of places. Unlike the common "BBQ" style
tank, these look more like a small acetylene tank. They have a
heavier wall, to resist punctures, and a top ring to protect the
valve. I use these in my studio, and would not consider using the
other type. Propane is stored as a liquid, and becomes a gas as it is
released. There is a LOT of potential in that little tank! Propane is
also heavier than air, so if it leaks, it will form an explosive
Therefore, you must use moderate care when using any compressed
gas. Keep the cylinder chained or tied upright, to prevent it from
accidently falling over. Every night, before you leave your studio,
make it a habit to "make the rounds." Turn off your gas/oxygen tanks,
turn off the pickle pot, turn of the steamer/sonic/ and any other
electrical devices, then turn on the alarm and turn off the lights.
You will quickly develop a routine. I don't always bleed my torches,
and I never change my regulator settings. I am only using 2-5 lbs. of
pressure, so there's not much strain on the diaphragm.
