After 30 minutes of pratice.

Never used a TIG machine. So I bought one, and the only thing I had on hand was a piece of aluminum.

So after 30 minutes or so this is what I got. I know that my a/c balance way off. But I'll fix that later.

Your filler looks reasonably consistent, but your weld looks cold. That's very typical of someone who's never tig welded and is trying to do alum.

If you are looking for suggestions, you need to post up your machine, settings, tungsten size, filler size, material thickness etc so we can make some useful suggestions.

I was running my amps max at 150ish. Using foot pedal.
%2- 1/16. 4043 1/8 filler. And the metal was 1/8 I think.

My buddy who is a pro, said I need to use a 3/32 tungsten instead of 1/16.

1/16th is good to around 140a depending on balance. If you dip lower than 60% or so, at 140A, you might split your tungsten or have it melt back. That's when you'd go to the next larger size tungsten... If yours didn't ball up all the way inside your cup, or melt off into your weld bead, you don't need to go up.
