Decrease Metal with a Torch (Oxy-Acetylene)
Choose the vastness cutting gratuity you itch based on the thickness of the metal you are cutting. In public a extent 0 cutting gratuity Testament spare your oxy-acetylene torch to chop metal up to a thickness of 1/2 inch. Depending on the cutting gratuity vastness establish your O2 and acetylene pressures in accordance with the manufactures instructions. I bag a proportions 0 gratuity with specifications of 25 psi O2 and 5 psi acetylene.2. With the O2 valve closed on the cutting torch expanded the acetylene valve slightly. Directly use a striker to light the end of the torch, being careful to hold it facing away from you and others. The flame should be orange and giving off a dark smoke. Gradually loosen the acetylene valve to increase the flow until the smoke disappears.
Oxy-Acetylene cutting is a widely used disposal to torch reduce metal of nearly any thickness up to 12 inches. It is used in industrial applications further as sculpting. Whether you are doing any metal working it is a needed facility. The next cue has come from my knowledge as a metal shop teacher and distinct demonstrations and lectures I annex attended over the carry on couple senescence.
Instructions
1.3. Now using the oxygen valve gradually increase the flow of oxygen until you see a light blue flame in the center of the fire from the cutting torch. Increase the oxygen until this light blue flame extends only about 1/4th of an inch from the end of the torch. This is called a neutral flame.
4. You are now ready to chop. Hold the torch just above the edge of the metal you are cutting allowing it to heat up. Once it is to the point where its glowing move the torch off the edge about half an inch and immediately trigger the oxygen lever and move back over the edge of the metal.
5. Gradually angle the torch into the metal being cut at about a 20 degree angle and slowly move across cutting it. You can tell the torch is cutting all the way through by watching the sparks coming out the bottom.
6. When you finish turn off the oxygen and acetylene valves on the tanks and separately bleed the lines running to the torch to release the pressure.
