14400/240 volt distribution transformer has a transformation ratio of 60,
so impedance (60Hz) of 0.1 uF primary cap at the primary side of pig
would be -7.37Ohm.
lincoln 225 welder rated for 230v 50a, so its impedance is 4.6Ohm,
we may don`t consider the primary impedance of the pig, then impedance
that`s "seen" from the mains side is:
4.6-7.37=-2.77Ohm
it`s about 957uF and you`re going to add another 700uF? you guys
really don`t understand what you are doing %-)))

Neon transformers are doomed in Tesla service! I should know, I've
killed more of 'em than many pople have ever even seen in a life time.
