welder flux to mig???

so i just got a lincoln hd weld pack welder. seems pretty decent to start out with. it plugs into 110v (standard house plug). the issue i have is it is just flux core. it has no place to plug argon up to it so i can run mig wire. supposodly you can convert it or something. has anyone done this? and wat will i need to do? it came with a spool of .035 wire and tip.

what is the difference with flux and mig? i know the mig wire is cheaper but u gotta get gas to. i like the look of the mig weld a lot more then flux. it seems a lot cleaner. and the flux seems to melt the metal more. it was turned way down and still cut thru sheet metal like butter. i am in no way a welding expert and want to learn more. thats why i got this welder. thanks tyler
