I am by no means an expert welder, but you should be able to get a decent
weld with co2 on a mig. You have to hold the nozzle close enough so the gas
can sheild the weld. Try turning your reg up a little for some more gas
flow. If you want a cleaner weld go with an argon co2 mix for a few dollars
more, or even straight argon for no spatter but it is spendy. Gas is much
better than the flux wire belive me once you get the hang of it you'll only
use the flux wire in an emergency.
