What is a key benefit of using CO2 in MIG welding?

The use of CO2 in MIG (Metal Inert Gas) welding is popular due to its cost-effectiveness and the ability to enhance welding speed. Using CO2 as a shielding gas tends to lower overall welding costs because it is less expensive than other gas mixtures, such as argon or helium. Additionally, CO2 provides a deeper penetration weld. This feature is advantageous as it can allow welders to work more quickly and efficiently, resulting in increased productivity. Therefore, the financial aspect paired with the mechanism of welding that CO2 provides excellent arc stability and penetration contributes to a faster welding process.

While it may have some effects on finish quality or cleaning needs, the primary advantages are tied to cost savings and the potential for faster operations within the welding process.
