That is a good point. MIG sucks outdoors with wind blowing.
A shield for the wind helps and increasing gas flow helps to a degree but raises consumables cost.
Al that shielding gas purpose is to shield away air so a stable arc is maintained. So anything that blows that gas away from the arc is bad. Including a fan blowing on you on a hot day.
