Scrapping a Vintage Miller SRH-333 Welder | Massive Copper Payout!

In this video, we tear down and scrap out a vintage industrial Miller SRH-333 welder (with components dating back through the 1970s and 1980s) to see how much copper, insulated wire, heavy steel, and resale parts are packed inside. Using an old Lincoln IdealArc as a makeshift workbench, we strip off the heavy casing, break down the massive transformer coils, sort the wiring, and recover valuable electrical components. We run into heavy-gauge 3-phase wiring, salvage brass hardware, pull out a solid cooling fan, and inspect the heavy-duty rectifier assembly to determine what makes more sense to resell on eBay versus selling straight across the scale at the scrap yard. Along the way, we break down scrap copper grading: why varnished and resin-coated transformer windings are classified as #3 copper at the metal depot, why attempting to burn off varnish is both illegal and bad practice, and how cleaning up windings and lugs helps maximize your scale ticket value. We finish with a full tally and weigh-in of the copper buckets, heavy lead cables, and miscellaneous non-ferrous metals to calculate total profit against the original auction purchase price.
