if you go looking for a specific inductor you will pay $$$, but if you
recognize that transformers are heavy and therefore of low value to whomever
doesn't need them, you have an approach. old filament transformers for
example, will have high current primaries which will give you some inductance
- you may need a few. I'ts easy to find low voltage transformers in the 10 to
50 amp range. Even old malibu light transformers may have adequate current
carrying capacity. And, with a transformer of this type (filament, etc) you
use the secondary for the current limiting inductance, and then can put a lamp
load across the primary to actually regulate the current that will pass (more
load will pass more current)

That is very true, you would definitely draw 3x more current than rated.
I want to thank everybody for their inputs. Anyway have you priced what it
would cost to construct a .19 Henries ballast? You sound like you're in
the same boat I'm in...no arc welder and trying to do this project on a low
budget. Let me know what you find out and I'll try to look into the
inductive ballast method myself.
Thank you
Rodney
