Welding gases are specialised chemical mixtures used primarily to shield the weld pool from atmospheric contamination. By excluding atmospheric contamination from the molten metal, these gases prevent porosity and brittleness while stabilising the arc.
We manufacture a comprehensive range of high-quality welding gases in Australia, all of which are available to purchase directly from us or from one of the many Coregas agents that can be found across the country. Whether you are looking for oxygen, acetylene, CO2, hydrogen, argon, or welding gas mixtures, such as our popular Coregas 5/2 welding gas (93% argon, 5% CO2, 2% oxygen), we have what you need. All of our welding gas products are manufactured to strict specifications and come with a certificate of conformance.
For details of our inert and active shielding gases, designed to be used in MIG, TIG and MAG welding applications, and our oxygen/acetylene products for cutting and heating applications, contact us now. We can help you navigate our complete gas range to find the ideal match for your specific base materials. We offer managed supply services for all of our welding gases, or you can simply order what you need when you need it.
With over 50 years of powering Australian industry, Coregas delivers the technical precision and supply reliability your business demands. Whether you need a standard shielding mix for high-speed fabrication or a specialised blend for critical infrastructure, our experts ensure you have the competitive edge.

Welding gases are essential for producing clean, strong welds. They shield the weld area from air during the welding process, helping to prevent defects such as porosity and weak joints. This results in better weld quality, consistency and structural strength.
It depends on the process and material. Aluminium needs argon, while mild steel suits argon/CO2 mixtures. As a welding gases supplier, we can advise on the best solution.
Yes. Always secure cylinders upright, check hoses for leaks and ensure oxygen fittings remain free of oil or grease.
MIG and TIG require external gas cylinders. Stick welding uses flux-coated electrodes to generate their own shield, removing the need for separate gas.
Absolutely. From engineering firms to DIY hobbyists, we supply professional-grade products regardless of your order size.
They are vital for construction, automotive manufacturing, shipbuilding, pipelines and general fabrication.
