My old welder machine, a Snap On YA212, suffered circuit boards death some years back. The tool guy tried to order boards for it, but they had obviously been superseded multiple times over the years (the machine was obsolete as far as Snap-On was concerned) so the boards just would not work correctly. One set made it turn on and feed as soon as it was plugged in, another just ran the internal fan and all else was dead, another ran the wire real slow and appeared to bypass the feed knob and the final tried one made it feed too fast, but at least with the trigger unlike the first board. So it just sat in my garage. A few years ago, I caught the same basic machine at an auction site for estate sales. So I went to the sale and scored the machine with a 265 bid. It came with 2 thirty pound rolls of wire and a full large sized Argon tank about half full, but lacked the cord to plug it in. Didn't care, I have a cord. I never really used the machine, just a quick zap to verify it worked, then it sat until I took it out to the shop/storage last year. My friend whom I split the shop/storage with is a Certified welder and I'm a self-taught welder but niether of us could get this machine "dialed in". We've been able to weld, but the aesthetics was lacking. Nowhere near pretty welds with this machine and it was quite frustrating. Well, Sunday he finally managed to get the welder dial in. He was fixing the frame horn on his new YJ I sold him over a year ago. Yes - it was sitting in my yard the whole time. I kept thinking to myself as he welded away while I wire-wheeled on my Willys PU frame was - 'love to hear him say he got the welder dialed in.' Well I reckon the real power of thought worked! He yelled over to me after playing around for 40 minutes - "Hey Hector, check this out we are flowing like butter." I asked where he was set at and he said dead even at 7 and 7. My old machine used to "default" at around 3 on the heat and 6 on the feed for most sheet metal and 4 and 7 respectively on frame stock steel or new exhaust pipes. Personally, I never had the settings match welding before. But that's what this machine likes, so be it! Was beginning to think it was a bad purchase. Turns out not so, hooray! Just in time too, since the PU frame is clean now and next step is fab and weld!
