Battery Spot Welder

I just finished making a Table and Case for my Battery Spot Welder.
For my design I used a Microwave Power Supply, a Weller Soldering Gun parts and a Bottle Capper to make it.
I mounted a Momentary Push Button on the handle so when I lower the contacts onto the Battery
all I have to do is push the button for power and then release it.

It works awesome and now I don’t have to buy expensive batteries anymore
for my cordless power tools.

That’s a lot of combustibles around a welding station.

I was referring to the wood used to construct the table and power supply cover. It does look very nice, but if I had something like that in my shop and my insurance agent saw it, I would receive a coverage cancellation letter in the mail shortly there after.

Thanks I also like what I’ve done with it. I did super insulate all of the wiring.
If I burn the house down it will be a good excuse to build a new one..:)

Interesting project.
Newer seen anyone make a diy spot welder. Would love to learn more – would you care to share some insights on the details, coustruction and wiring etc?
What do you plan to use it for? And how thick/what kinds of metal can it weld?

Thank you for sharing!

Hi kaerlighedsbamsen,
Just Google “Microwave Spot Welder” and there are tons of videos on how to make them.
That’s how I found them.. I just designed my own setup is all.. it was not my idea.

Very interesting what people do to reuse discarded equipment – Thanks for the info, it lead me to some in-depth study on exactly how microwave ovens work.

DANG! And just 2 weeks ago I threw out a 10 year old convection/microwave because the turntable no longer spun and the convection oven had quit
