Hobart Hefty CC/CV

A fellow that I work with has this Hobart Hefty CC/CV suitcase wire feeder
and I would like to buy it from him (he says it is about 6 years old but
never used). I have seen it and it looks brand new, complete with gun and
regulator. I have a Lincoln Ranger 8 engine driven welder without the
optional remote contactor and I was wondering if I could weld hard wire as
well as dual shield fluxcore wire with this suitcase wire feeder?
I have used suitcase feeders before on jobsites but only with a
self-shielding fluxcore wire using straight polarity, it works but I prefer
using CO2 fluxcore or solid wire in my shop.
Or do I need to get a different feeder and install the remote contactor in
my welder to change from dual shield fluxcore to solid wire using reverse
polarity?
