I always have .035 in the machine, only switch it and the gas that has the oxygen in it out to weld 16 gauge and below. 10 and 12 gauge would be fine with the .025 probably beter but not worth switching for. I get occasional blow troughs on 12 gauge if I hesitate or don't have a perfect fit up but blame that more on the gas. The 2% oxygen makes the arc a LOT hotter.
