MIG welding is a widely used welding process for mild steel due to its ease of use, cost effectiveness, and great results. Shielding gas is an important factor in this process, and the best shielding gas for mild steel MIG welding is a mix of 75% Argon and 25% CO2. This gas mix provides better arc stability, deeper penetration, and less spatter than other shielding gases.
With so many shielding gas for mig welding mild steel brands on the market like PRIMEWELD, Varies, Generic, it can be tough to know which one is right for you. Don’t worry, we’ve got you covered.1. PrimeWeld 75% Argon 25% CO2 Bottle 125CF | DO

Best shielding gas for mig welding mild steel Buying guide
When shopping for shielding gas for MIG welding mild steel, several factors should be considered.
The most common shielding gas for MIG welding mild steel is a mixture of 75% Argon and 25% Carbon Dioxide (commonly referred to as 75/25). This gas offers a good combination of weld penetration and bead shape while keeping the cost of the gas relatively low.
Another option is a mixture of 90% Argon and 10% Carbon Dioxide (commonly referred to as 90/10). This gas is slightly more expensive, but offers a slightly better weld quality with deeper penetration and less splatter.
Finally, some welders prefer to use 100% Argon. This gas is the most expensive, but provides the best weld quality with the deepest penetration and least amount of splatter.
When shopping for shielding gas, it’s important to consider the cost of the gas, the quality of the weld that you need, and the type of welding you are doing. Each of these factors will help you determine the best shielding gas for your project.
