Possible reactance for pole pig


        I was talking with a fellow who is in the neon
sign business and I spoke to him of Tesla coils and my
pole pig that I have not yet used. He told me that he
has a similar transformer there that he uses to 'charge'
the neon tubes. He spoke of a device that he called a
'choke' which is how he limits his current. I asked
him to describre it further and from what I gather, it
is a cylindrical heavy coil with a slideable metal
core through it. He said it was rated at 200 amp and
cost about $700 new. Has anyone here heard or seen one
of these? I am going to go down to his shop to see for
myself. I wonder if this can be used on the pole pig to
limit current.
