Hey guys, I'm new to this sort of thing but just wondering if any one can shed any light for me the value of a Snap-On YA 212A. Friend had one in the back of his shop that had been sitting there for a few years. He thought he bought it about ten years ago. I brought it home and with the help of 1-800-abc-weld got it working. Seems to be working fine at this point. Any help would be greatly appreciated. Thanks much in advance.
