Low voltage very high current rail distribution

I have some mains toroid transformer220v/12v, and thinking to add a few one-two turns fat coil in parallel, like in picture. Red are working windings, purple (top and bottom) is rails who connect all low voltage windings.

Question is, how to connect that device to be as much more efficient in spot welder operation to distribute and pulls currents to all winding equaly, minimalize voltage drop?

output on half E-F
output on C-B
connect A-B and C-D, output on A-F
otherwise?

Re: Low voltage very high current rails distribution

if you're planning on rails like that, it doesn't matter, all the same. You get better results if you just weld the wires together into one ring, but if you truly want better you wire all windings to the exact two same points and connecting those to the output wires instead of using a rail. Yes, more wire, but if you want best, that is the best.
