Actually, I would call it a choke, but reactor is what you
see most often in reference to welders. I'm just a lowly old
tech, so what do I know... For a picture see:

It would help if you had a core to wind the turns around.
Don's idea to find some diodes and make a little DC welder
is really good. Then you could most definitely use the
reactor. That would make a nice little DC box.
Another thought is to try using it in the low or middle
output range. It is very possible that it could actually
have a higher VOC in those ranges. I know the VOC on my dual
range buzz-box sucks on the high current tap. The low-range
tap is much higher.
