start with some E6010 (home depot sales it), weld on DC+ and just spend a few nights welding lines in some scrap steel. don't get lazy and weld the dirty/painted steel, take a few more minutes to clean it before you start. And post some photos so we can see those first welds.
My other hint is that one of those auto-darkening helmets will make it way easier to weld with. The cheapo ones from harbor freight work just fine. That way you can see what you are doing all of the time.
So a E6010 rod would be best for all around use? So is DC+ reverse polarity and, DC- is negative polarity? Will a E7018 rod work better with DC?
It looks like from looking on Linclons website that I can run the 7018AC's I already got will run on DC+. So they won't be a waste after all.
I never said my notes were accurate
