==Safety
* If you smell acetylene, shut off the tank by turning the handle at the top of the tank clockwise.
* Don't operate the torch with the regulator set to 15 PSI or higher (the red zone on the left gauge). Acetylene becomes unstable above 15 PSI.
* Don't tip the acetylene cylinder on its side. If an acetylene cylinder has tipped over or was stored on its side, carefully place the cylinder upright and do not use until the liquid has settled to the bottom. The rule of thumb is not to use the cylinder for as many minutes as the cylinder was on its side, up to 24 hours.
==Turning on the torch.
# Install the tip you need on the torch.
# Make sure the torch valve is shut (clockwise).
# Turn the pressure regulator T-handle counterclockwise until it is loose.
# Open the valve at the top of the cylinder 1/4 turn counterclockwise. The right gauge should now be showing the internal pressure of the cylinder and the left gauge should be at 0 psi.
# Turn the pressure regulator T-handle clockwise until the desired pressure (12-14 PSI) is shown on the left gauge. Don't let the pressure get into the red zone (above 15 PSI).
# Open the torch valve a small amount and use a striker to light the torch. Never use a match or cigarette lighter!
# Adjust the torch valve to achieve the desired flame size.
