Corgon (mixture of Argon & CO2)

Corgon is a shielding-gas mixture of argon and carbon dioxide used mainly for MIG/MAG welding. The argon provides a stable shielding environment, while CO₂ contributes to arc characteristics, heat transfer and penetration.

Compared with 100% CO₂, argon/CO₂ mixtures can provide better arc stability and reduced spatter, depending on the mixture and welding conditions.

Common Mixture

  • 80% Ar + 20% CO₂ — widely used for MAG welding of unalloyed and low-alloy steels, suitable for different arc-transfer modes.
  • Other ratios are also supplied for specific welding requirements.
