Voltlog #207 – Making a DIY Spot Welder From A Microwave Transformer

Welcome to a new voltlog, today I’m gonna talk about a DIY spot welder that I built, the advantages of suck a build as well as the disadvantages or the the problems I encountered. So the idea for this project started many months ago, I was actually at a local recycling center to deposit some old electronics, when I saw this microwave oven transformer sitting right there on a table, like the guy in charge of the place literally took the transformer out of a microwave oven a few hours prior to me arriving there.

So that sparked the idea in my head, I asked the guy if I can have the transformer, he said yes and that was the start.
