Hello All,

I've read postings suggesting that an AC arc welder can be used 
as a current limiter for a pole transformer.  I'm curious about a 
couple of things.

How are the welder and pole pig wired together?

Also (and this is a bit off-subject), just how does an arc welder 
work?  What is the current limiting mechanism, and how is it made 
variable?

Lastly, can a pole pig be current limited by means other than an arc 
welder or series power resistors?

Cheers,

Greg
