- Acetylene is a weird gas. A
- large volume of acetylene at
- pressures over 15 psi is un-
- stable and can explode like
- nitro-glycerine. But as you will
- soon find out, the pressure in a
- full acetylene tank is over 200
- psi! The reason the tank doesn't
- explode, is because the tank is
- first filled with acetone, a
- liquid. The acetylene is then
- pumped into the acetone. As you
- use the gas, it boils out of the
- acetone. The acetylene tank must
- be upright when used, or the
- acetone could flow into the
- regulator.~

- Regulators are very sensitive to
- dust. This step is considered
- good practice by some, but un-
- necessary by others. You be the
- judge. While wearing goggles,
- open each tank valve for a
- split-second to blow dirt away
- from the opening. This will be
- loud.
