Try using a lens or kicking up the CFM, i see a lot of dirt in that weld. It looks like you scraped the black off it with a wire brush before you took that pic.
Did some Aluminum welding at work the other day... I still need a LOT of practice but at least im getting something that resembles a bead now

Ha... looks like my practice welds. First try in 15-16 years.
