C02 in mig welding acts to shield the arc and the weld pool from out side contaminants, it's not a great inert gas but it's cheap. 100% Argon is used in tig welding to give a very stable arc but is around 2/3 more expensive. Basicly the more stable you can get the weld pool (molten material to which the filler is added) the better penetration and stronger the weld is. 10-15% Argon mixed in to C02 will stablise the arc between the filler wire and the weld pool during welding, it means the weld will be cleaner as the filler rod will effectivly become more fluid like a stream of water from a tap rather than a dripping one. I hope this makes sense to some one
