I use boss spot welder for copper.

Boss level custom spot welder

I just got a couple days ago a custom spot welder. It has tons of potential so i want to share this info with the community. I live in a small house, we are swimming on electric and painting stuff so i can’t afford to have big machines. I looked for small custom spot welders on the net: microwave, car battery, supercapacitors… all of them too big or not what i was aiming for. Then i found this welder. It’s not a new device, was created time ago, since it is interesting many guys tried to buy it…
