In part 2, the size of the big transformer was revised, to lighten the device, because the very strong power exceeded expectations.
This industrial transformer was then replaced by a microwave oven transformer, turning the power from 3000 to 2000 watts, with a smaller and more compact device. because of the difference between the two devices, the second video has not been named "part 2", but in fact this is part 2 of this video.
