The studs are not just run through a hole the face is slotted and they are mounted on a plate. It looks factory and I have seen this style before I just cant remeber on what year machine. He painted it so much its hard to get any numbers or anything. But I welded with it for 20 minutes burning 3/16 8010. It didnt smoke, bog down, or anything. I may send this one to Kaye and keep it.
