Hello Nick,
Make sure you earth the EI core and fuse everything - primary should have slow-blow fuses. Make sure your solid-state relay is rated for inductive loads and has a snubber network... use a mains filer to prevent the cr*p getting back into the house power. If you can afford it, use a zero-crossing solid-state relay. Its simple to do this with discrete components - avoid uPs - they may well object to the huge current pulses flying around and are a completely unnecessary complication. eBay 380381237513 looks like a suitable SSR at a fair price.

Thanks for the insight, but the filtering does not sound trivial to me. As it appears, MOT spot welders can also be made without any electronics: http://www.youtube.com/watch?v=VG1xVNpm7k8
How much current is actually flowing in the primary circuit? Best regards, Jens -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
