An oxy-acetylene torch is a tool that can be used to weld two pieces of metal together. While the torch can make welding seem easy, the safety precautions that professionals take when using the torch are complex and essential. If you have never used this tool before, make sure you work with it under the care of an experienced welder.

Difficulty: Challenging
Instructions

Things You'll Need:

  • Oxy-acetylene torch (includes valves, adjusting screws, connecting hoses, etc.)
  • Welding goggles
  • Leather apron
  • Leather arm coverings
  • Leather gloves
  • Steel-toe leather boots
  • Striker
  1. Step 1

    Clamp the two pieces of aluminum together to prepare them for welding.

  2. Step 2

    Stand to the side of the cylinder. Open and close the valve as quickly as possible. This will remove any dirt from the cylinders, and is called "cracking the cylinder."

  3. Step 3

    Attach the regulators and the torch head to the cylinders.

  4. Step 4

    Put on welding goggles, a leather apron, leather arm coverings, leather gloves and steel-toe leather boots. Make sure there are no gaps between the different pieces of protective gear.

  5. Step 5

    Make sure the valves on the torch head are closed. Very slowly, open the acetylene cylinder about a quarter of a turn.

  6. Step 6

    Very slowly, open the oxygen cylinder all the way.

  7. Step 7

    Open the acetylene valve on the torch. Quickly activate the striker and hold it to the gas. Adjust the flame to the appropriate strength using the adjusting screw on the acetylene cylinder.

  8. Step 8

    Turn the adjusting screw on the oxygen cylinder to the desired pressure. Then slowly open the oxygen valve on the torch.

  9. Step 9

    Hold the torch head up to the pieces of aluminum. This should weld the pieces together.

  10. Step 10

    Close the acetylene valve, followed by the oxygen valve, on the torch head. Then close both valves on the cylinders.

  11. Step 11

    Open the torch valves once more to relieve the pressure. The valves on the cylinders must be completely closed before you do this.

  12. Step 12

    Release both adjusting screws.

Tips & Warnings
  • Do not operate acetylene gas at a higher pressure than 15 psi. The torch is more than hot enough to melt human flesh, and some molten metals can cling to your skin. Be sure that your skin is covered at all times while operating the torch. Do not weld galvanized steel; the coating on it can release dangerous particles when heated. Make sure that your welding area is properly ventilated.
