Introduction: Microwave Oven Transformer Welder.

Picture of Microwave Oven Transformer Welder.

There's already a great instructable for how to build this here

But I thought I'd post some pictures of what my friend and I came up with as our finished product, and just show off a little.

The picture quality is likely on the "eh" side, I'll get some new ones with a camera that isn't my cellphone soon. It works though. That silver dot in the last picture is a hole I filled in a bar of 1/4" steel with some 1/16" 6013 welding rod I picked up at Harbor Freight for 5 bucks. It welds pretty nice actually.

I'm in the process of dismantling a micro-wave right now. I've stoped for a lilttle while to be sure I'm doing a safe work of dismantling the electronics inside. I haven't shorted the potentially lethal capacitor yet. Good job! I'll be done soon though!

When we were dismantling our ovens, we got all geared up to short the caps and... nothing happened. I was most displeased.

Most newer ovens come with a resistor screwed to the frame so the capacitor discharges... but sometimes this fails... and one time I got a nice melted/burnt dot on a screwdriver :P better to make sure!!!

Better this than not being geared and having something blow up in our face :P The capacitor CAN hold a charge for a long time, but that doesn't mean it will absolutely I guess..

nice setup I've been wanting to do this instructable too. just don't have the time. did you put the transformers in a chest?

It's an old Soviet rocket box. I'm actually on the lookout for a new enclosure, as this one has dry rot.

Soviet rocket box! Hell yeah! :D

how about using one of the old microwaves? that would be kinda cool unless its in pieces beyond repair?

Grimarr (author)tech_sponge612009-03-09

That's... actually not a bad idea. I'll have to see if we can put the old radarange together. I'm thinking of something a little less huge though. Have to see what turns up.

yea i guess easy transport would be nice.. if you do find some thing cool to house it in let me know. good luck.

definitely, I plan to add photos to this if we change anything.
