I bought a welder as part of a large lot from an auction, I'd like to use it but I don't know how to, or whether I've got all the parts I need, so I'm looking to get a manual for it. I tried through Sears, but 3 months later, they finally admit that it's no longer available. Sears, Roebuck & Co. Craftsman Home n Shop 50 Amp Arc Welder (115V), Model # 113.201420. I've seen that manuals-online have shown that this manual was available, but link(s) now lead to totally irrelevant manuals.
