Cylinders should only be used and stored in the vertical position.
Warning: never clear a fuel gas cylinder near other welding work that is in progress or near sparks or flames.
If the regulator and cylinder have different threads (meaning they don’t fit into each other), you will need to use an adaptor, which can be purchased at any local hardware store.
If you ever need to make an adjustment after the cylinder has been opened and used, make sure to close the cylinder valve before tightening the nut again.
When the screw turns freely, you should be able to just tap it with your finger and see it move, rather than having to apply pressure.
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. [6] X Research source
In general, it’s smart to work in an area where you can reach all your tools without having to search for them. Think ahead when you are starting a project and bring your tools to your workspace before beginning.
A hose with a natural rubber liner is okay for acetylene service.
Don’t force connections—if the threads don’t run together easily by hand, either the threads are damaged or the parts aren’t meant to go together.
Most new oxy acetylene torches come with built in adapters, but double-check with the manufacturer’s instructions to be safe.
Double check your connections before moving on to make sure everything is hooked up to the right place.
Having tight connections is extremely important because they will keep both the oxygen and acetylene from leaking.
It is very important to test for leaks before starting your project. Leaks can cause harm to you or your surroundings and may lead to spontaneous combustion of the cylinders.
Any work brush you have on hand will do; just make sure it hasn’t been compromised by oil or gas.
Give the solution 1-2 minutes to sit before checking for leaks.
If after you’ve tested and refastened any leaking areas you are still seeing bubbles, that may indicate you have a leaky hose and need to get a new one before moving on with your project.
Don’t set the pressure higher than what the equipment manufacturer recommends.
If you open the valve too fast or too far, you may cause the canister to combust.
Heating, welding, and cutting cause smoke and fumes that are bad to breathe in and that can irritate the skin.
You can also search the manufacturer online to check out more information regarding your tool. A lot of sites have community forums where people post tips and stories about their experiences that you can learn from.
Remember to not have the oxygen gas flowing when you go to light the torch. [21] X Research source
The lighting procedure should result in a neutral flame, which is blue in color and which does not make a hissing sound. [22] X Research source
If in doubt, turn off the gasses and check your machine over before proceeding.
If your torch keeps experiencing flashback, there may be a damaged piece that needs to be returned or replaced.
