How to build a Spot Welder with a microwave oven transformer. Never connect the transformer to the grid before removing the secondary coil, because it produces 2000 Volts at 500 mA, this is LETHAL. A secondary with more turns than primary rises the voltage. On the other hand, a secondary with less turns lowers the voltage and put more amperes to draw. With a thick cable we make a 2 turns coil that delivers 2 or 3 volts and many many amperes. This is why the cable has to be very thick.

Hi. My name is Darek and in this video I'll show you how I made a Spot Welder DIY using simple tools.
The main assumption was to make this without special tools.
As you seen, mostly I used a drill and an angle grind and the end result came out really cool.

Costs:

A transformer from the scrapyard — $ 2.00
A welding cable 1 meter — $ 2.00
Connectors — $ 1.00
An aluminum square tubing — $ 4.00
Door hinges — $ 2.00
The rest of the materials I had in the workshop, but if I had to buy them, would not cost more than $ 10.00
—————————————————————————————————————————————————-
$ 21.00 (my cost $ 11.00)

The welder works really, really well. After a few minutes of work, only the aluminum arms are warm. Thanks to the fact that they are made of aluminum, they quickly give off the heat and the entire transformer and the coils are cold.
