Re: Welder replacement

Hi Kevin,

> How would you determine what size welder to use with a particular sized xfmr?

A welder for use as an inductive ballast is chosen based upon it primary current rating.
If you require 40 Amps for your maximum current value, you need a welder that has that much
current capability in it's primary (240 VAC) winding.  The current rating of the welder will be 
on a tag on its case.
