Making a Spot Welder from an old microwave
Inspired by http://mad-science.wonderhowto.com/how-to/turn-microwave-oven-transformer-into-high-amperage-metal-melter-0140772/
Disclaimer, you really should not do this. Don’t try this unless you are really sure you know what your doing. Mains is dangerous, and microwaves even more so.
Work in Progress

For something that is not meant to be user-serviceable all these components came out really easily. Here is what I was after

A little disappointed its a small plastic transformer. I was expecting something bulkier and with a stronger metal case. But I will try it anyway

Removed the copper with some clippers and a screwdriver. the plastic is very brittle and breaks off easily, need to be careful

and out of it a new transformer, much more like what I was looking for. I also bought a circuit breaker so I don’t necessarily blow the mains if this one is faulty too
