A few other gases are also important. For example, you may see Helium blends used to weld thick aluminum.weldguru.com/best-gas-for-mig-welding/For MIG welding, use a shielding gas that suits your material. Common options are: 100% Argon for aluminum, a 75% Argon/25% Carbon Dioxide mix for mild steel, and a 90% Argon/10% Carbon Dioxide mix for stainless steel. Choose the appropriate gas for optimal weld quality and appearance.beginnerweldingguide.com/what-gas-to-use-for-mi…MIG welding (GMAW) is a gas shielding metal arc process that uses the heat of continuously feeding an electric arc between the consumable electrode wire and the base metal. GMAW uses argon, a mixture of argon-helium, and CO 2 as well. DC Constant Voltage Machine performs MIG welding.www.weldinginfo.org/welding-processes/mig-weldi…Argon is the main shielding gas used for Tig Welding and for Mig Welding Aluminium or Mig Brazing. The most commonly used Active Mig Welding Gas is a mixture of Argon and Co2, although Pure Co2 is also still used.www.thewelderswarehouse.com/blog/mig-welding-…If you’re going to be MIG welding, there are two main gases that are used: pure argon and an argon/carbon dioxide mix. The most common (and recommended) Ar/CO2 mix is a 75/25 ratio, with 75% of it being argon and 25% of it being CO2. Which one is used for what?unimig.com.au/which-gas-do-you-need-for-your-mi…
