That I am happy. I tried my first welding of aluminum today.
Setup: Millermatic 200, Miller Spoolmatic 1 gun, wire: .030 4043 (that is all that they had), material 1/8 plate of scrap aluminum, unknown alloy, pure argon @25 cu. pr. hr.
I ran one inch and burned a tip. I then got extremely lucky and ran a (to me) beautiful bead of about 8 inches.
Then, burned another tip. Adjusted gun wire feed and diddled around and some looked like I had been doing it forever and some looked horrible.
All in all, I am extremely pleased and elated with this process.
Naturally, I need a lot more practice but it is much, much easier than I had envisioned.
Thanks to all who gave advice and especially to Ernie as I peppered him with questions.
I don't know whether 5356 will be easier or tougher but I will get some spools of it soon.
Now, watch my luck, I will never run beads as good as I did today!

Some were sooty, is that too much current/wire feed?
