Many oxygen bottles are filled with over two thousand pounds per square inch which is a high-pressure bottle. If the valve is damaged or broken it will literally fly around your shop breaking everything in it's way.
You need to protect your valve. So whenever this bottle is not in use and the regulator's off or you intend to move the bottle, you need to use a protective valve cover even when the bottle's empty. Next, the torch supplier will share the following content with you.
Acetylene gas is unstable at pressures over 15 pounds per square inch, so acetone is used inside the bottle as a stabilizer. As the acetylene is being filled, it's absorbed by the acetone. These bottles need to be straight up and down when in use.
Now whether these bottles are in a portable bottle cart or up against a wall, they need to be chained up securely. This is real important. You do't want to be able to pull them over with the hose or knock them over.
These bottles are regulated by the department of transportation. You need to secure them properly (chained), straight up and down when you transport them.
The oxygen regulator: and before you mount the regulators, stand behind the valve opening and crack the valve to blow out any dirt or moisture. The high-pressure gauge measures the pressure inside the bottle. The low-pressure gauge measures the working pressure coming out of the regulator.
Regular adjustor: Screwed in or clockwise increases the pressure, and screwed out decreases the pressure. It also measures the pressure in side the bottle.
Acetylene is unstable at pressures over 15 pounds. The pressure adjustor is the same: screw in to increase the pressure, screwed out to decrease the pressure.
The fittings on the fuel gauge regulator are notched to indicate left-handed thread. All the fittings on the fuel side of this equipment are notched with left-handed threads to avoid mixing the equipment and getting an oxy fuel gas mixture where you do't expect it.
Red hose for acetylene and a green hose for oxygen (usually). Quarter inch is a stand hose size for normal cutting stations, and section of 3/16 hose is often added at the torch end.
Flashback protectors. In case fire heads back down the torch these stop it before the fire heads down the hoses and regulators. You will buy these seperately:
Cutting goggles: I like the type that fit's over safety glasses, a number 5 filtering lens, and I also like to use clear plastic lenses in front and in back to protect the filter lens.
Good leather gloves. It gets hot!
Wire brush: for cutting metal that's dirty, rusted, or painted.
