12000 Volt Arcs

12000 Volts at 400 and 600mA is used to make some arcs. The transformer used was made from 6 MOTs. Each MOT core was cut open, freeing the E part from the I part. Two E sections were then put together with one primary between two secondaries on the now larger core and the result welded up, giving a 4kV transformer. Three of these were made and put in series under oil in a large case. Caps from the microwaves are used for secondary side ballasting to limit the current as there are no shunts in the transforme
