Unitek Unibond II Resistance Weld Head Power Supply

Got this Unitek Unibond II power supply unit here. It's an older piece of industrial equipment, looks like it was used for precision welding or bonding. The casing has some wear and tear, some scuffs and old tape residue as you can see in the photos, but the switches and dials are all there. Has settings for pulse amplitude and duration, plus a feedback mode toggle. Not sure on the exact working state since I haven't tested it fully, so selling as-is. Good for someone who knows their way around these older lab or shop tools.
