It depends on geographic area what the used price is. Some are very old. I can honestly say that I have used many of these units in many shops. Although I have seen other makes and models sitting in corners discarded I have never seen a millermatic abandoned. On .035 wire they will run forever without missing a beat. Larger shops which do large weldments often have these smaller machines exclusively doing light fabrications like handrailing. I did run into one that had its feeder rolls shaft bent. How that happened I don't know but I hammered it so that it ran reasonably true and it was back in service. I suspect someone was hamfisted on the roller pressure/wire tension. I have heard of millermatics with different branding go for as little as
500 but they were pretty beat up. The one I saw was also covered with overspray, likely from a body shop. Randy
