Carbon Dioxide for Metalfabrication Industry

The active gas most used in welding processes.

First gas in MAG welding

The characteristic of having a low ionisation potential, meant that this gas was chosen as a vehicle for the generation of an electric arc. Today almost always mixed with argon, it has the function of restoring part of the carbon that is lost during the welding process and of releasing oxygen as active gas in the process.

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