if you are referring to flux core wire welding, it will weld sheetmetal but is'nt nearly as neat and pretty as gas shielded wire welding. take some good advice (hope others will back me up) if you decide to buy a wirefeed that uses fluxcore (gasless), buy one that can be converted to gas shielding later. fluxcore weld quality is just as good (so i'm told) but the weld is ugly and very hard to clean up. the first wirefeed i had was flux-core (gasless), and i hated it til i sold it and bought a gas shielded machine. i have a lincoln 135plus (120V and you can take it anywhere) and love it for thin metals. i also have the big daddy miller 350p wirefeed which makes my old stick arc machine collect dust and spiderwebs now.
