Safely add a Flyback Transformer to a an electrical fence transformer to make plasma?
I have a very old outlet powered electric fence charger that I recently took apart because it was broken. I took out the transformer and hooked it up to the wall (110v 60hz) bypassing a large resistor and capacitor and was able to get a stable arc of plasma about 1/4" long. As best i could tell the transformer does not have an internal rectifier so the output was AC. As for the voltage and the amps I can't tell, The limit of my multimeter is 500v and it went past that even with the resistor and capacitor hooked up to it and the output voltage is not labeled on it.
I am hoping to connect a Flyback Transformer to this to make a Jacob's Ladder and possibly experiment with some plasma. I do not yet have one but I am currently looking at a few on Ebay that are standard in Sony TVs.
So i guess my questions would be: Is it safe to connect a flyback transformer to it? Is it even safe to hook up 2 transformers in that manner? Would it burn it out? And what kind of Voltage could I expect out of it? Would that kind or brand work well?
Any help would be appreciated,
