from what you are decsribing, its a mig only machine. the wire should fit through the feeder with proper adjustment. that machine should take the large and small spools. the only thing you should have to change is the tip size for the differnt wire. go to any welding supply for gas. as for my first home welder, i have a hobart 125 (i think its a 125) mig. i am still using the gassless flux core in it due to the portability and ablility to weld anywhere with it and not worry about the gass being blown away. at work i use to use all miller stuff. for stick we use the big miller 6 pack machines, for tigging on the ships we use the dynasty or maxstar machines. tig in the shop use the big liquid cooled millers, and for dual shiled flux core and alumnium we use the suitcase hooked to the 6 pack.
