Key Features and Benefits:

  1. Enhanced Arc Stability: The Pacshield 80/20 Argon mix combines 80% argon and 20% carbon dioxide, providing excellent arc stability during welding processes. This stability ensures consistent and controlled heat transfer, resulting in improved weld puddle control and reduced spatter.
  2. Increased Penetration: The addition of carbon dioxide in the gas mix enhances weld penetration, making it suitable for thicker materials and challenging welding environments. This increased penetration leads to stronger and more reliable welds, even in demanding applications.
  3. Reduced Oxidation: Argon 80/20 creates a protective atmosphere around the weld area, minimising oxidation and preventing contamination of the weld metal. This results in clean, high-quality welds with improved mechanical properties and corrosion resistance.
  4. Versatile Applications: Our Pacshield 80/20 Argon/CO2 mix is suitable for a wide range of welding processes, including MIG (Metal Inert Gas) welding, flux-cored arc welding (FCAW), and metal fabrication. Whether you’re working with carbon steel, stainless steel, or non-ferrous metals, this gas mix delivers excellent performance and weld consistency.
  5. Cost-Effective Solution: By optimising shielding gas composition and performance, Pacshield 80/20 Argon/CO2 offers a cost-effective solution for welding applications. It helps improve productivity, reduce rework, and lower overall welding costs while maintaining high weld quality and integrity.
