Carbon Dioxide (CO2) for Metal Fabrication

The most frequently used active gas in welding processes.

The most important gas in MAG welding

Carbon dioxide (CO2) is known for its low ionization potential. That is also why this gas is used to generate an electric arc. Nowadays the gas is almost always mixed with argon. Its function is to restore some of the carbon lost during the welding process and to release oxygen as an active gas in the process.

It makes the arc very stable and allows a wide penetration into the joint to be welded.
