Home-made spot welder. I wanted to make some metal boxes and trays. I have plenty of scrap sheet metal from things like old PC cases and microwave ovens. I already built a sheet metal bending brake. Now I just need a way to fasten parts together.he internet has lots of articles about how to make your own spot welder, so I'm not going to repeat everything here.
