“Need help deciding which Ar/CO₂ blend is right for your welding process?”

Base material thickness is probably the most important variable. Welding on thicker materials requires more penetration; therefore, choosing the correct shielding gas mix and wire is critical. 

  • For thicker weldments above 1/8”, 75/25 Ar/CO₂ with flux core wire or 90/10 metal core wire can improve penetration.
  • 75/25 flux core offers great versatility in all positions and is the most common in commercial production welding shops for structural weldments.
  • 90/10 metal core makes the weld puddle soupy, more fluid, and harder to handle for vertical and overhead positions. However, it has great penetration for flat and horizontal on T and Butt Joints.
  • 75/25 solid wire and short circuit transfer is typical when welding on 1/8” material or less with the correct amperage and voltage. This allows for better control and welding can be done in all positions with less penetration above 1/8” weldments. The 75/25 gas mix works great for sheet metal, car body shops and thinner mild steel weldments.
