    Are you talking about a wire feeder or running a mig welder off of your gas welder?
    If its a mig welder,all you are using from the gas welder is the generator side.Set everything else[wire speed,voltage,polarity]from the mig welder[hh210.mm180,lincoln180,etc]
    If you have a wire feeder,you are using the gas welder as you welding power also.There is a selector switch for cv or cc.Some machines have a polarity selector switch on them [-dc-electrode neg.for flux-core].Other machines you have to switch the leads around .If your feeder can run from cc or cv,there should be a selector switch on it.If you chose to run on cc,leave the switch on the gas welder on cc mode[stick] and put the switch on your feeder to cc.If you chose to run on cv,put your switch on both machines to cv[cv is the better choice in my opinion,runs a lot better out of position].Main thing to rememeber is both machines need to be on the same thing[cc or cv]flux-core-dc electrode neg.You will also set your voltage when using [cv] on the current dial on your gas welder.wire speed is set on the feeder.All current[cc or cv] will be set on gas welder.Hope this helps and doesnt confuse.

      One more thing dont forget to hook the control wire clip from the feeder to your work piece.Need a good clean connection.

          I thought pipe had to be either stick or TIG welded.

            mig is probly the fast and easiest method of welding pipe at least in my experience.
