If y'all think that there's at least 100 amps involve I'd think
that it would work perfectly. If there's much less than 100 amps involved,
the stabilizing effect would just be reduced proportionally. If this is
the case you could do things like put two in series (too expensive) or, if it's
open-frame construction, just add more turns to it.

Surplus Center has listed in there catalog: "Welding Generator
Reactor for 100 to 300 amp generator ... Acts as arc stabilizer ... for units up
to 300 amp." I wonder if this would work out. it is listed for $32.50 but my
catalog may be old there number is 800-488-3407 tom >>>>
Reactor and choke are other names for "inductor". An inductor has wire
wrapped in a coil so that a magnetic field forms when current flows. I didn't
know they used these in DC welders, but it makes sense since the energy stored
in the magnetic field would be released when the arc started to go out, the
collapsing magnetic field would increase the voltage, and the arc would be
helped along. So it sounds like an inductor is used for stabilization like
someone said. It would also help striking. For a situation like this I'd think
it would be heavy copper wire wound around an iron core. The easiest thing to do
might be to hit a DC welder in a junk yard! >>> Neil Dennis

you use DC rod and have the correct polarity ? Second, about the reactor, we
need the expertise of an electrical engineer ( of which I' m not). Basically,
the draeings I remember used a coil of heavy iron wire (like a big resistor) to
stabilize the initial surge of current. Don't know beyond that. wombat
