 I have two flat wire wound , variable inductors for sale. since i
acquired
a very nice three phase welder with a
 500 amp voltage variac along with a three phase 500 amp variable
inductor i don't think i'll need the 150 amp spacer adjusted inductor.
any one interested contact me at :mystuffs-at-orwell-dot-net.
These are factory units exactly like richie bernets coustom built units,
if not satisfied and not burnt, i will replace cost and shipping. i
guaranty that i rang these out with my lcr meter with several spacer
thicknesses and they will run 20 to 100 and 20 to 175 amp (respectively)
pass with no excessive heating! These are current limiting inductors out
of complex AC motor drives.
pictures can be supplied, or seen on my web site.
