Many years ago I made a few trades and wound up with a Miller XRA AL wire feeder with one working gun and a second partial gun for parts. It was hooked up to a Thermalarc 4000 multi process power source and the one time I tried it the thing worked fine. Weld just sucked because I unknowingly was using Argon/CO2 instead of straight Argon. Fast forward to now and someone at work decided the Thermalarc needed killed, so no more power source. I have a Primeweld AC/DC TIG now so not much use for the Miller and was thinking of selling it. Prices are all over the place and few seem to be selling. Any advice? Fair price, where to advertise, any demand for them? Asked a couple local fab shop guys if they wanted to make an offer and had no interest at all.
