is it possible? ive got a miller dynasty 200 and was just wondering if i could buy a spool gun to use the dynasty as a power source.

Yes and no

Spool guns generally work off of CV power sources - Your Dynasty is CC, so the short answer is no.

Is it possible?
Yes (kind of) Some wire feeders can work off of a CC power source if they have a voltage sensing cable, So it's possible to power a wire feeder off of a Dynasty. If you can power a wire feeder, you can power a spool gun from the wire feeder (in theory). Is this practical? Hell no - It would require so much adaptation, you'd be better off buying a stand-alone mig (+ spool gun if you mig Aluminum). My machine has a CV tap (directly powers a wire feeder) and it's STILL more cost effective and easier to get a stand-alone unit for wire feed welding.

definately doesnt sound practical. miller has their dvi box thats voltage sensing, but my dynasty has more power (200 amps vs 170?) plus i dont think the dvi box has quite the range of input voltage (110v-440v,1p or 3p). plus it only weighs about 50 lbs. :) just a thought anyways. thanks for the info.

voltage sensing cable to sense contact and power the gun across the arc, not "input voltage sensing" like on a DVI. look at the small ground clip on this Miller wire feeder- that's a voltage sensing cable.

Cobramatic has a gun that will work with some adaptation, but they aren't cheap.

you can use a readywelder, they have a separate power supply to power the spool
the ADP model will work

spool gun

Better off buying another welder. Tried to do the same thing just too expensive. Just ended up finding a 1 year old esab multimaster 260 with the spool gun, like the miller xmt models. Picked it up for about $2,000
