Carbon dioxide 50L (37.5kg)

Designation

Applications

Specifications

• Chemical activity: CO₂ is an active gas that reacts with molten metal and can cause oxidation.
• Arc temperature: CO₂ creates a relatively hot welding arc compared to inert gases (mix of Ar + CO₂).
• Type of welding: CO₂ is typically used when welding steels, particularly low-carbon and low-alloy steels.

Application Information

• Cost-effectiveness: CO₂ is cheaper than inert gases (such as argon), making it popular for welding structural steels.
• Deep penetration: CO₂ provides deep penetration of the metal, which is useful when welding thick materials.
• Availability: Carbon dioxide is widely available in cylinders and easy to store.

• Spatter: Welding with pure CO₂ produces more spatter compared to inert gases, requiring additional cleanup of the weld.
• Oxidation: As an active gas, CO₂ can cause oxidation of the molten metal, which may reduce the quality of the weld.
• Harsh arc: The arc with pure CO₂ can be less stable and harsher, making it difficult to work with thinner materials.
