CORGON® -  Argon and CO2 mixtures

Gas mixtures with Argon as a main component – ideal as protective gas for MAG welding.

CORGON® 18: 82% Ar + 18% CO2

        - Shielding gas (short arc and spray arc) for MAG welding of unalloyed and low-alloyed steel
        - Also suitable for cored wire electrodes

CORGON® 8: 92% Ar + 8% CO2.

        - Shielding gas for MAG welding of unalloyed and low-alloyed steel with spray arc

CORGON® 25: 75% Ar + 25% CO2

        - For MAG welding of unalloyed and low-alloyed steel
        - Suitable for short arc MAG welding

CORGON® 3: 90% Ar + 5% O2 + 5% CO2.

        - For MAG welding (spray arc) of unalloyed and low-alloyed steel

Forming gas - Nitrogen and Hydrogen mixtures

Forming gases are the group of gas mixtures containing hydrogen and nitrogen in different proportion. Using Forming gas eliminates the need for post-weld cleaning with low surface oxidation.

Following gas mixtures are available: 

  • Forming gas 5 - 95% of nitrogen and 5% of hydrogen
  • Forming gas 10 - 90% of nitrogen and 10% of hydrogen
  • Forming gas 15 - 85% of nitrogen and 15% of hydrogen
  • Forming gas 20 - 80% of nitrogen and 20% of hydrogen
