Kevin nailed it! PRACTICE!!!!! Find some similar metal to what you're going to weld and dial in your settings for that session. If, no matter what you do, the .035 isn't working, switch over to the .030 and try to dial things in. Or vice versa. Dial it in on scrap until your happy with the weld and are in a place where you recognize and can adjust to mistakes quickly. Similar to painting. You don't just load up the gun and start laying it on. You do a quick test spray to dial in your pattern and atomization. I've welded with all kinds of machines and filler material. It all needs to be dialed in. Whether sheet metal or angle strips for beds.
