Old Marquette welder

Gary, our maintenance boss at work decided to get some welding done at the top of the house bins which are 6 stories high. The old welder that they used for years up there (and has not been used for years) was looking pretty sad and to top it off the clean up crew threw out the leads for it. So he went out and bought a new Lincoln 225 AC/DC welder to keep in the power room up there. He made me a deal when I asked if I could buy the old one. If I got the new welder to the 6th story, I could have the old one, (in otherwords I would have to bring the old one down).
This is an old 275 amp AC welder that's gotta weight about 1 pound per amp. Gary said it worked good the last time they used it about 8 years ago. It has always been dry but in a dusty mill enviroment. My thoughts are to do with this what I did with the old (about the same vintage) Craftsman welder we had on the farm that got flooded back during the 72' flood. I just stripped that down and power washed all the internals then blew it all out with air the let it set for a week to dry out. That one worked fine and still does to this day. Anybody know of a source for information on this welder?

Moving it to my garage, I have to say you're 100% correct about the weight of that sucker. But it's about as reliable as anything I own. When you get some info about the lead connectors, please share. I need to replace my ground lead, as the old natural rubber is in sorry shape, and if I can get a new connector where it plugs into the welder, I figure I'll be ahead of the game.
