it sounds simple, try the next setting down? if you have fit up thats not the best with gaps it is easier to burn a hole. if you do burn a hole let it cool a bit and you can turn your settings down increase your stickout length or increase your gun angle to put more heat back onto the weld.
even the type of material you have will change how it welds so what might work for this wont for that.
75/25 would be better if your having trouble with holes.
pay close attention to whats happening and what things look like just before making the hole (not always easy) and you might be able to stop before you have the problem.
if worse comes to worse stitch weld it up. shouldnt take long that way at all
make sure polarity is correct before you start.
