Well, the wire clearly says CO2 Shielding gas which means it is not flux core. If you look at the recommendations on your machine, it recommends gas for under 20 gauge. I don't care for for flux wire welding, but if you weld where it is windy, it is your only choice.
I have a little Lincoln machine exactly like you have. I use it to weld light stuff in the wind or a quick weld where I don't want to carry a whole lot of contraption to it. This is the wire I use.

It clearly says flux core.
