Wow, lots of great info trg!
My Lincoln is a a 115V unit. I have (or rather, did have) it set up for aluminum with the sleeve. Originally, I had the knurled drive wheel on it but as it was pointed out to me, that's the wrong wheel. I have the correct wheel now.
I'll try it with the wire you described. What I have been using is the .030" wire.

Although I have the inner Teflon sleeve for aluminum, my welder is currently set up for welding steel as I have a couple projects for work to do. Switching it is a PITA, which is why I was thinking of going to a spool gun.

So when I get back to teaching myself, I'll try your suggestions and see how it goes. Thanks for the advice!
