I converted this 120v impact wrench into a scissors jack operator. The kawasaki wrench never worked properly and it was about to be thrown in the garbage after years of storage.
The universal motor in the impact works great off DC. I housed a DC DC boost converter in an old drill battery case with cooling fan.
Step 2: Completion and Testing.
The impact is powered off 90vdc, uses 400watts and raises the car pretty well. For the test I used a portable lifepo4 battery but for a tire replacement on the road, I will plug the xt60 connector into my car's power system.
Not bad for an old bogus tool to be repurposed into a useful application.
