I would like to present here a soldering welding
Lets begin with a transformer from a microwave
Now it is time to take of the output winding with much care
Now there is only the input winding
We coil a think cable ,i think its around 20mm diameter..We round 2 times this cable to the core of the transformer. The thicker the cable, the more current to the output. The length is around 1 meter
I will place it in a metallic box
I will connect the switch to the first winding
Here is the upper arm rounded by a piece of copper for holding the upper spike
I do the same the under arm
And now about spikes.Those spikes are from bronze .We could made those from copper or something else, but from testings i found that bronze are the best because stewing slowly.
That’s all, it is ready for testing
