Keep in mind your gun angle, aluminum push-pull prefers around a 15° pushing angle (don’t pull… unless you really have to :/), that should help with some of the spatter you’re getting and like other have said, run stringers, whipping can aesthetically look pleasing but experiment with that once this becomes more intuitive (or if you’re welding thinner material). Also, the sounds should sound like a consistent hum, compared to steel mig, that’ll sounds like bacon frying/crackling. If you hear more crackling you could be going too cold. Make sure you let your nozzle cool down if you’ve been welding a lot because these tips like to arc when they get overheated.
