Re: [TCML] Good and Cheap Ballast Options (fwd)



I used one of the lincoln "tombstone" welders in my pole pig setup. It worked great. I didn't like the idea of tearing apart the welder, so put an electrical socket on the outside of my power cabinet. It was wired in series so when you plugged the arc welder in and shorted the output, it controlled the current to the pig. The great plus is that you still have an arc welder if you aren't running your coil. You can make all sorts of stuff with it.

I have a bunch of stranded 10ga THHN wire if you'd want to pick it up. It's still on a spool, probably 50-80 lbs of it, so if you found the inside end, the coiling it up is done for you. I'm a little north west of Denver.

Dave,
I have heard of the welder option before, but one of the drawbacks is that
they are bulky. On the other hand, a commercially made welder should be
pretty robust and handle some heavy duty cycles! That said, I do have two
120vac MIG welders, and I don't want to sacrifice them. The selector
switches seem to be potentiometers so I am not sure how it is limiting the
current. Maybe a 240vac stick welder is a different beast though. Thanks
for the heads up about the magnetic forces at play!
