Oxygen-Acetylene or Oxygen-Propane Torch

Make sure you have access to a fire extinguisher before you start your cut.

Open the valves of the cylinders slowly.
Make sure the gauge of the acetylene cylinder does not exceed 15 psi. Drawing acetylene too quickly produces an unstable, explosive condition.
The oxygen gauge should be set around 50 psi.
Check the torch hoses and gauges for leaks, damage or deterioration. Never use a torch that leaks.
Clear all combustible material away from the cutting area.
Open the fuel valve on the torch (Propane or Acetylene). Light the gas.
Slowly open the oxygen valve on the torch.
Getting the right mixture of oxygen and fuel requires a little practice. Get help if you have never used a torch before.
Before you start to cut, check the area once more.
Make sure the hoses are clear of the cutting area.
After the cut is complete, turn off the fuel valve on the torch first.
After the flame is extinguished, turn off the oxygen valve on the torch.
Close the cylinder valves.
Keep the torch and hoses free from oil
