Hobart 180

Yes, the machines are always set up for flux core. That's why they supply a 2lb reel of the stuff with each machine.
You should've read the manual, it explains how and why you have to change the connections for solid wire

Are you running a bead on one side of a solid sheet, and expecting to see a similar bead on the underside? How thick is the steel?
