Acetyleen C₂H₂ - B5
An Acetylene C₂H₂ - B5 gas cylinder is a specific 5-liter (water capacity) industrial gas cylinder filled with dissolved acetylene gas, primarily used for mobile brazing, oxy-fuel welding, and small-scale cutting work. Because pure acetylene is extremely unstable under pressure, the B5 cylinder is fully filled internally with a porous mass (monolith) and a solvent (usually acetone). In this state, the gas is safely dissolved.
Thanks to its extremely high flame temperature, acetylene is ideal for various industrial processes:
- Oxy-fuel welding and cutting: Joining or separating metals.
- Brazing and heating: Very localized heating of parts.
- Flame melting and gouging: Surface treatment of steel and concrete.

Information
Safety
Why safety is crucial
Acetylene is chemically unstable and can decompose explosively at high pressure. To prevent this, the gas is dissolved under pressure in acetone, which is distributed within a porous mass inside the gas cylinder.
Essential operating procedures Because acetylene has specific storage and usage requirements, you must always adhere to the following guidelines:
- Always upright: Store and use the acetylene cylinder strictly in an upright position to prevent the gas from separating from the acetone.
- Let it rest: Gas cylinders that have been lying flat or have just been delivered must rest in an upright position for at least 1 to 2 hours before use.
- Protective clothing: Always wear heat-resistant clothing, a welding helmet or safety goggles, and gloves.
- No copper or silver: Acetylene reacts with copper and silver, which can lead to explosive copper acetylides. Therefore, do not use these materials.
