DIY spot welding machine from old microwave transformer

Making DIY spot welder with pulse timing control and old microwave oven trafo.
In this video I used double layer of 8 AWG (10mm) wire for the secondary winding of the transformer.
Output voltage is 2.5 volt and LOTS OF AMPERE!
There is a cheap module to control the impulse timing. It can be set for specific cases.
Name of the module to control the impulse: XY-J02 (from AliExpress).
