  • Portable Spot Welder

    I found this at a garage sale several years ago. It operates off of a 12-volt deep cycle battery. A push button operates a solonoid which makes the circuit. Hold the button as long as you need to, not very long. The lever operated mechanism "cams-over" to hold the work pieces for welding. I mounted it on a small hand truck. Works well on light gauge for small projects. It's not for production use.

        Dave, Did you ever check how much amperage it draws. I use a 10 amp charger to run my 12V air compressor on 110v in the house. I use it to inflate toys for the kids, etc. I was wondering if you might be able to do the same thing here to eliminate the battery.

          Nice easy way to build spot welding tongs. Just what I need another project.
