Howdy!
I have a Thunderbolt 225 that my grandfather bought in the early 70's and I doubt has burned 20lbs of rods; he got sick in '75 and it sat for about 20 years before I got it and it's been sitting in the barn pretty much since then. Last weekend I pulled the amp control wheel off of it and sprayed a little WD-40 on the threads of the shunt block. It turns fairly easy but I'm wondering whether or not I should buff the rust off the sides of the shunt... remember this thing hasn't been turned on in over 20 years. I need to hook up an air hose and blow the whole thing out, as I removed a double handful of mud dobber nests from the bottom floor of the welder. What should I do to make sure I don't burn it up the first time I plug it in? I have other welders, so I'm not completely ignorant of mechanical workings, but given the sentimental value of this machine to me, I'd like to keep it around and working as intended. Any ideas, thought, suggestions, and/or advice is most welcome- and thanks in advance for your attention.
PS- my machine is similar to the one attached here, but instead of a silver adjusting wheel as pictured, mine has a black one. Everything else is nearly identical.
