Should be clean. There is something seriously contaminating the weld pool.
I don't scrub my Alu unless absolutely needed.
The black specks and scummy dull grey should not be happening.
On the pic below look past the fact they are quite uniform that's just lots of practice but it's the cleanliness you should be looking for.
