Re: [TCML] Saturable reactors for TC Current limiting?

["Teslalabor" <teslalabor@xxxxxxxxxxx>]

I think Dave knows about that and the reason he asked for saturable reactors 
is that he wants an alternative way for current limiting than simply using a 
shorted welding machine. So in this topic should only be discussed saturable 
reactors so you shouldn't post something about welding transformers...
