These mixtures are used for spray arc and short-circuiting transfer on a variety of carbon steel thicknesses.

Used for conventional and pulsed spray transfer welding of carbon and low-alloy steels.

Bead shape is good.

Weld metal mechanical properties are excellent.

Welding fume levels are low with both solid and metal-cored wires.

For all-position pulsed spray welding of thin and heavy carbon and low-alloy steels.

Most applications are on carbon and low alloy steels.

Storage racks for automotive industry

Railcar centre sills and side panels (metal and flux-cored wires)

Backhoes and front-end loaders

Wheel rims for cars and trucks

Motorcycle and truck frame fabrication; engine cradles. Farm implements.

This mixture also operates well in high current applications on heavy materials (mild steel) and can achieve good arc stability, puddle control and bead appearance as well as high productivity.

A 75% CO2 mixture is sometimes used on heavy wall pipe and is the optimum in good side-wall fusion and deep penetration. The argon constituent aids in arc stabilization and reduced spatter.

A 75/25 argon and CO2 blend is typically considered to be the best overall option for MIG welding.
