Hi,
I have built a microvawe transformer spotwelder, I have put a single turn of welder wire for in the secondary and I'm timing it with arduino. Worth mentioning it was/is a 230V transformer. Electrodes are sharpened copper rods. I believe the voltage is still high. The spotwelds it produces are slightly discolored and not as strong as you would expect. Is this design fundamentally borked? Is there anything else I can make to make it better?
Photo from test stage before it was built into a project box, it is less "shocking" now.

I need lower voltage. 1-2V on the secondary. I have 3V rms now.
