what does polarity do

On my Millermatic 115 you can reverse the polarity what is this feature used for

-------------------------------------------------

bare wire mig requires dcep (reverse polarity) but some flux core wires require dcen ( straight polarity). you can look up the maker of the flux core wire and find a data sheet that lists the correct polarity....its a big deal too.

flux core that is designed to weld on dcen will run like crap on the wrong polarity
