This Lincoln came with two spools of wire. .025 solid core wire and a spool of the flux core wire. Also has the necessary gauge and hose to hook up a gas tank of argon or whatever they recommend. For structural welding like I did today I think flux core is fine since nobody will see it and I'll just grind it smooth. For fender surface replacement I might need something with less slag deposit on the weld. Got some video coming up of the weld but not uploaded yet. This one is from a couple of days ago.
