Oh yeh, 6011 I know. Actually I first tried that rod before I hooked up a 240v outlet (I got a one of those dual range welders), I was really shocked how much penetration it accomplished on 1/4" plate even on 110v, wow!
Guys, I've been playing around with 6013 and 7018, I do ok with them I think, for a newbie. But then the other day I had something to actually do, I got a part I broke a tap in while power tapping into a blind hole (which a real machinist wouldn't attempt, but I ain't a real machinist). So what I was trying to do was to weld a 1/8" little piece of metal to the broken off tap in there, so I could screw it out. I had no luck with that, I was blowing right through that 1/8" little piece of plate with both 6013 and 7018. I had the amps down as low as I could to still be able to get an arc going.
So I've been researching that a little since then, read about swapping leads around to dcen, I gotta try that still.
But then yesterday I stumbled onto these little things at Menards:
