“Need help deciding which Ar/CO2 blend is optimum 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.

High-performance gases for high-quality welding and cutting

The Maxx™ shielding gases deliver the highest levels of performance—including better weld quality and faster welding speeds—to maximize productivity, reduce rejects and improve your working environment. Our shielding gases exceed the requirements of all relevant gas quality and mix accuracy standards and include all industry standard welding mixtures.
