Good point. Thanks for the reply. Yes, it is a .025mfd capacitor. I
remember when I first fired this coil I was using one of these same neon sign
transformers and a home made rolled poly cap of .019 mfds. The gaps did fire
with several gaps in series and sounded much hotter than this one does now.
I was reluctant to fire it with the pole pig because it is somewhat
difficult to control at low current. At the lowest welder setting I think I
get about 10 amps which is 2.4kva. With no primary, I thought this might be
quite a jolt for the capacitor - and of course I didn't really want to ruin
it if it is any good. I also was reluctant to pull the rotary gap out of
the current setup, but maybe I will have to.
