Jacob's ladder and microwave oven xfrmer

jacob's ladder would provide sufficient current limiting? Also, the voltage
is pretty low, so maybe a MOT isn't worth it anyway?

which can easily result in insta-death. That said, I have seen some
impressive ladders built with them. I don't suggest it personally, but
there are a few sites which outline the designs, as well as the hazards.
Sam Goldwasser has a page on it in his repairFaq, the direct link is below.
A brief summary of his article is 'Jacobs ladders built out of MOTs is a
dumb idea' worth a read as to why. (This also includes a link to a website
discussing wiring MOTs in parallel for some strange reason :) )

Although neon transformers offer low current which kinda sucks, you can
parallel them (make sure to get them in phase) for higher currents. I ran
one which consisted of two 15kV/30ma transformers in parallel and it had
pretty nice results. The page below has a picture of a ladder using 5
OBIT's in parallel.

I recently lost the net connection for my web server, or I would offer up
links to my page with pics as well.
At any rate, there are plenty of other options besides a MOTs, the
associated hassles, and dangers.

I've build ladders using NSTs. I was hoping the increased current would provide
for a more "intense" arc. I think perhaps the danger and lower voltage means I
should just stick with paralleled NSTs.

Rewinding the secondary can be useful . Sam discussed ths on his website also . :)
5V at 100A could be useful .

Just an idea (a bad idea, I know... ;o), and note that I've never
tested this : you could parallel the NST and MOT outputs, properly
phased. NST gives high enough voltage for even a larger gap (spark
rises much more easily) to ignite. The MOT supplies the high current
once the gap has been ionized and once it turns into a low impedance.
=> large white flame
Of course, the MOT has to be protected from the excessively high
output voltage of the NST, as the MOT secondary isolation likely will
not withstand those 8kV/10kV/15kV. Maybe a >15kV >1A diode on the MOT
output lead, and the NST left ungrounded. The MOT other output lead is
grounded/case, so grounding the NST too would cause a huge amount of
troubles...
The MOT makes the system just that bit more lethal.
Although, even with a NST one can get killed very easily, so using a
MOT doesn't really make _that_ much difference (ok chances are slimmer
you'd survive a MOT than a NST, but then, who'd want to take ANY
chances with high voltage...).
be careful,
cheers,

Um, just because the short circuit capacity of MOT's is higher than NST's
doesn't mean that an NST won't kill you under the right conditions.
Both are potentially deadly and NST's _have_ killed people. If you treat
both with appropriate and equal respect, you won't get dead.
If you're determined to use MOT's, you'll probably want to put a "ballast"
impedance in series with it/them. See the Sam's FAQ link that Jon
thoughtfully provided.
