- Gas Range
- Acetylene
Acetylene
The hottest, most versatile and most efficient of all fuel gases, acetylene is often used in combination with oxygen for welding, brazing, cutting and soldering.
C2H2
Due to its low ignition energy, acetylene is easy to ignite in oxygen or air. Oxygen and acetylene combined produce the hottest flame of any welding gas mixture. Now available in E and D size from selected stores.
Uses

- Oxy-acetylene cutting
- Welding
- Flame heating
- Flame hardening
- Flame straightening
- Flame cleaning
- Thermal spraying
- Gouging and brazing

Frequently Asked Questions
-
Where can I buy Trade N Go Gas acetylene gas?
All Trade N Go Gas can be purchased directly from Coregas or from one of our stockist - no account is required.
-
How is acetylene stored?
An acetylene tank should always be stored upright and secured in place with chains or other suitable restraints. This is because acetylene gas is mixed with a solvent (usually acetone) to prevent decomposition, which can lead to explosions. Storing the cylinder tanks upright ensures the gas does not separate from the solvent. Additionally, the distance between acetylene cylinder tanks and other cylinders, goods and features should be to Australian Standard 4332-2004 in order to ensure safe storage.
-
How long does acetylene last?
Your acetylene usage will depend on the specific application but for safety reasons, it is not advisable to use flow rates greater than one tenth of the cylinder tank’s capacity. For example: with a single cylinder tank that holds 9.3 cubic metres, your flow rate should not exceed 0.93 cubic metres per hour.
-
Can acetylene burn without oxygen?
Acetylene gas can burn in normal air without a supply of pure oxygen but for heavy duty heating applications, an oxy-acetylene mix is needed to reach the required flame temperature.
-
Why should oxygen and acetylene be stored separately?
Due to the potential for dangerous reactions when mixed, oxygen and acetylene cylinder tanks should never be stored together. Please refer to Australian Standard AS 4332-2004 for additional information on storage for acetylene.
-
Why is acetylene used in welding?
An oxy-acetylene gas mixture is capable of producing a flame with a temperature of around 3,100 degrees Celsius, which makes it an excellent choice for industrial steel welding applications in Australia, New Zealand and across the globe. Unlike propane, acetylene gas produces a reducing zone when burned in oxygen, cleaning the metal surfaces being welded.
-
What size oxy/acetylene cylinder tank should I get?
This depends on the required flow rate and usage requirements. Multiply your required hourly flow rate by 10 and this is the minimum acetylene cylinder tank size you will need. For flow rates that exceed our largest cylinder tank size, manifolding several cylinder tanks together may be the best solution.
