    Apr 18, 2012· I’ve spent the last couple of weeks building an arc welder by winding new secondaries onto two microwave oven transformers (MOTs). The one important lesson to learn from all of this is that high power transformers are not a place where the “fuck it that’ll do” method works; I wrecked a couple of primaries so ended up having to find fresh MOTs and start again.
