I have a Miller welding arm and post for sale. $200. It come from Industry and the welder and wire feeder controls have been discontinued. You can buy new units that will retro fit onto these arms. The new units would be the Welder, wire feeder control and the wire feed rolls out on the end for the guns. That would cost you about half price of a new outfit. The one I have left,the arm has been shortened to 10'
