What is the ratio of CO2 and argon for MIG welding?
A 75/25 argon and CO2 blend is typically considered to be the best overall option for MIG welding, so that’s our top recommendation at Vern Lewis Welding Supply. A “tri-mix” of helium, argon, and CO2 is also sometimes used.
How much does argon CO2 Mix cost?
75% Argon / 25% CO2 Tank Costs
| Size | Initial Cost (full) |
|---|---|
| 40CF | $240 to $280 (example) |
| 80CF | $290 to $330 (example) |
| 125CF | $380 to $410 (example) |
What is the cheapest MIG welding gas?
CO2 (carbon dioxide)
CO2 (carbon dioxide) is the most affordable gas among the four gases used in MIG welding. You can use it in its pure form and, therefore, you don’t need a secondary gas.

Which gas is best for MIG welding?
argon
The basic gas for MIG/MAG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades.
Can I MIG weld with just CO2?
The most common of the reactive gases used in MIG welding is Carbon Dioxide (CO2). It is the only one that can be used in its pure form without the addition of an inert gas. CO2 is also the least expensive of the common shielding gases, making it an attractive choice when material costs are the main priority.
Can I use 100% argon to MIG weld?
Can You MIG Weld Steel Using 100% Argon Gas? It’s a question every welder will face at some point, and yes, you can MIG weld steel if all you have is pure Argon.
Can I MIG weld with 100% argon?
In summary, it is possible to stick steel together using a good MIG welder with 100% Argon shielding gas. But, you end up with a shoddy-looking, weak, brittle weld. If you need a strong, quality weld, 100% Argon is NOT a good choice for MIG welding steel.
