"MIG" and "MAG" welding are very similar, but there is a subtle distinction between the two. MIG (Metal Inert Gas) uses completely inert gases that do not react with the weld pool. MAG (Metal Active Gas) uses active gases that may react slightly with the weld pool, influencing the arc characteristics and penetration. What shielding gases are commonly used for MAG welding?

A) Argon

B) CO₂ or Argon + CO₂/O₂ mixtures

C) Helium

D) Oxygen
