  • Cutting, Separate and cleaning the secondary Winding -> Anode High Voltage Coil. 
  • When are used even only two turns of 35mm2 Large area Wire the transformer primary Magnetic field inducts into the improvised 2 – turns secondary coil Uout ~ 1.5 VAC and ability to produce an Impressive Iout current – more than a few hundred Ampers. The demonstration with melting and destructing of the metallic screws is a very indicative.
