Vintage Rocky Mountain Dental Spot Welder Machine, Dentist Welding USA, Medical Instrument Industrial


This is a vintage dentist Spot Welding Machine in very good overall condition. Shows signs of use, but no abuse. Clean and intact. The one tiny "lever" that goes through the end of the main chrome "L" shaped piece in center may have been a bit longer at one time, looks to possibly have been snapped off the end of it. The base measures about 8.25" x 7.0" x 4.25" and the center L chrome piece stands about 4.0" high.

The ID plate at left side where the red knob is reads "Serial No. M 438 Volts A.C. 110 Rocky Mountain Metal Products Co. 1450 Galapago P.O. Box 1887 Denver Colorado, U.S.A."

I plugged it in briefly and I pushed the plunger on left down and I heard it start up or at least HUM, then I shut it off, I do NOT KNOW if it is FUNCTIONAL or not, or even if it should be used. It is being sold as a scientific medical collectible. Sold in as-is condition with no guarantees as to it operating or not. Weight is just over 12 lbs.
