MIG welding stainless steel requires a very specific gas mix to ensure a successful weld. The best gas mix for MIG welding stainless steel is an Argon/CO2 blend, usually containing a ratio of 75% Argon and 25% CO2. This mix helps to protect the weld from oxidation and ensures a deep, clean weld. The addition of CO2 also helps to increase weld penetration and speed up the welding process.

Best gas mix for mig welding stainless steel Buying guide
MIG welding stainless steel requires a higher quality gas mix than mild steel. The ideal gas mix for MIG welding stainless steel is a blend of 90-98% Argon, 2-10% CO2, and sometimes a small amount of oxygen. This mix allows for a higher level of shielding gas and a better welding arc. Argon is an inert gas that provides the necessary shielding action, while the CO2 provides the cleaning action and the arc stability. Additionally, the oxygen can be added to increase the penetration of the weld and to increase the strength of the finished weld. Keep in mind that a higher concentration of CO2 often leads to porosity in the weld, so it is important to maintain the correct ratio of gases to get the best results. When shopping for the best gas mix, look for a mix that is specifically designed for MIG welding stainless steel. This will ensure that you get the best results and that you are getting the correct ratio of gases for your particular application.
