MIG shielding gas

MIG shielding gas is a premium gas mixture used mainly for the MIG welding of carbon steel. It is great for clean, quality and economical welds.

Ar / CO2

MIG shielding gas is specially formulated to give excellent arc stability with very strong welds. The carbon dioxide (CO2) in the mixture improves the shape of the weld bead. Now available in D and E size from selected stores.


  • MIG welding of mild steel, stainless steel, low alloy steel and galvanised steel
  • MIG welding of metal plate, tubing, sheet metal, furniture and automotive
  • Minimal spatter, good weld appearance and good control make it ideal for positional welding
  • Commonly used to weld thicknesses up to 8mm, but note this also depends on the capacity of the welding equipment in use
