Using .035 aluminum wire

I was using the aluminum spool that came w/ the Lotos (and was unmarked in terms of alloy). Right after I posted this and switched to ER4043, and it seems to be much better, although still pretty horrendous compared what I'm sure any of you could do!

I am new to welding generally and very new to aluminum. My aluminum welds are just absolutely horrendous and I’m not exactly sure what I’m doing wrong...
