I have an old (1960's) Lincoln Idealarc 500 AC/DC I got from my grandfather. It is about 4-1/2' tall by 3' square and weighs between 500-800lbs. It will squat a half ton truck pretty good. This baby takes 3 phase, a minimum 225 amp service. I have tried to sell this but with the size, weight, power consumption, and asking price....I have found no one interested. There is no way I could use the power of this thing or justify keeping it due to it's size and power requirements. I have been thinking there must be alot of copper in it but I'm not real sure if it worth taking apart. Would any of you have any idea about how many pounds of copper it may have? I have attached a link to the manual which has the specs and pictures of exterior and interior. Any help is greatly appreciated!!!!!!!!
