Shielding gas
What is argon-CO2 mix used for in welding?
Quick answer
Argon-co2 mix is used for MIG on steel (Argoshield-family 92/8 to 80/20), typically at 12–15 L/min. More CO2 = deeper penetration, more spatter; 92/8 is the Australian hobby standard

Australian supply notes
Common argon-family cylinder sizes: D ≈ 1,700–2,000 L, E ≈ 4,000–4,600 L, G ≈ 8,700–10,200 L free gas — but always read your cylinder label, since volumes vary by supplier and fill pressure (BOC, Supagas, Coregas). Estimate your consumption with our gas flow calculator before choosing hire vs swap.
