..... I learned real quick that to much heat is your enemy!!
the "too much heat" you speak of may also be a factor of not enough wire feed speed going into the puddle. If there's not enough filler for said amount of heat, its going to burn something, namely the parent metal. I find more heat, more feed speed, and LESS time on the trigger will get you a flatter weld that's easier to planish and clean up. And as Kevin said, practice on some scraps of the same thickness to get the machine AND yourself dialed in.
