Hey bro I have a Lincoln Weld-Pak 3200HD (which is a home depot model hence the "HD",Lowes has same model but is called a Pro-Mig 135 or something) and it is just like yours except it came set up ready to use flux core or run gas. Turn it all the way down, real slow feed speed, and like everybody else has said, lots of little tack welds. I've even done this successfully with flux core, but your life will be a lot easier with gas and thinner wire. If you haven't already, get yourself an auto darkening welding hood too. Don't get frustrated, it will get easier. Practice, practice, practice....Translation=Perfect reason for more projects and more toys...lol. Good Luck to ya.
