As a kid, I had a model train set with brass rails, and I remember that ... but nowadays I have a TIG/stick welding machine that has solid brass DINSE connectors, which sometimes need to carry 310A @ some low voltage (maybe 20-30V depending on arc length?).

Considering the high currents and fairly low voltages, I wonder why they don't use something other than brass...
