Re: [TCML] Jacob's Ladder

[DC Cox <resonance@xxxxxxxxxxxx>]

You can use nsts just as they are for nice climbing arcs.  They have
internal current limiting.

The MOTs require a series power reactor to limit the current.  You can run
two with the secondaries in series and primaries
in parallel.  I use a separate reactor on each primary leg to limit current
to 12-14 Amps.  With two in series it gives a real
powerful climbing arc.

Also, be careful.  The MOTs must be very similar or identical in design or
you will get powerful circulating currents in the
primaries which will blow your fuses or damage the MOTs.
