Re: "Copper/nickel sandwich" buses for series connections

if anyone wants to do this i highly recommend using nickel plated steel
i can weld 0.1mm copper at 1000A and it's really good welds, pure nickel doesnt stick at 1000-1300A
the only downside is it sparks alot, so wear eye protection. pure nickel doesnt spark

thanks author for good info
