Can you use acetylene without oxygen?
Decomposition is a chemical reaction whereby acetylene breaks down into its constituent elements, carbon and hydrogen. This reaction gives out a great deal of heat, which can cause the gas to effectively ignite without the presence of air or oxygen.
Do you need goggles for acetylene torch?
Generally, people who work with torching are either wearing a full face shield with a lens (either an electronic shaded lens or a green glass lens) or they’re wearing safety glasses.
Why does my acetylene torch keep going out?
The reason that an oxyacetylene cutting torch will pop and go out is because of a problem with gas flow. Usually this is either an issue with flow settings, a leak or blockage.
What happens when you lay an acetylene tank on its side?
Acetylene cylinders must not be placed on their sides, since the acetone and binders will have dislodged. The result may be formation of an acetylene “pocket” that is subject to polymerization and the possibility that liquid acetone will be released into the regulator.
What PSI should oxy acetylene?
In case the recommended working pressure settings are not indicated, safe numbers are 40 psi for oxygen and 10 psi for acetylene, regardless of cutting tip size. Simply adjust them until you get a neutral flame, but pay close attention to the acetylene pressure to prevent it from exceeding the limit.
What happens to acetylene above 15 psi?
Acetylene is highly flammable under pressure and is spontaneously combustible in air at pressures above 15 psig. Acetylene cylinders do not contain oxygen and may cause asphyxiation if released in a confined area.
Is oxy-acetylene bad for your eyes?
Oxygen fuel cutting, gas welding and brazing can expose workers to this type of radiation. Exposure to UV and IR rays can damage the eyes and the skin. Protect yourself while using oxy-fuel torches by wearing eye protection that has a welding filter lens designed to protect the eyes from visible, IR and UV rays.
Can using a torch hurt your eyes?
It can be caused by all types of UV light, but welding torches are the most common source. That’s why it’s sometimes called ‘welder’s flash’ or ‘arc eye’. Flash burns are like sunburn in the eye and can affect both your eyes. Your cornea can repair itself in one to two days, and usually heals without leaving a scar.
How do you mix acetylene in a torch?
A larger flame is suitable for thin material and a small flame for thicker material. After adjustment of the acetylene valve add oxygen using the mixing valve. Start to mix it when valves are fully closed. Full open mixing valve slowly until you get the neutral flame. Once the flame is adjusted, then the torch is ready to roll.
When to open the valve on an oxy acetylene torch?
Open the oxygen valve very slightly at first and pause until the pressure gauge hand isn’t moving any more before moving on to open the valve fully. The acetylene valve should never be opened more than 1 and 1/2 turns. 7 Leave the wrench on the acetylene valve while it is open.
How do you set up a cutting torch?
Once the hoses are firmly in place, connect the other ends of the hoses to the handle of your torch. Connect your cutting torch to its handle and tighten the nut by hand. Ensure that the valves on both the torch and the handle are closed. After setting up, you still need to do some checks before attempting to light your cutting torch.
Can a natural rubber liner be used on an acetylene torch?
If one of your hoses have broken, replace it—don’t use tape of any sort to try and patch the hole. A hose with a natural rubber liner is okay for acetylene service. Do not use any oil or grease on the hoses. All the connections from the gas supplies to the torch are metal-to-metal, and they don’t require lubricants or sealants.
