Jon,
I agree, I once had the priveledge to wire a testing station for spot welding guns for automotive manufacturing.
The leads to the guns were about eight feet long and made of 500mcm welding cable.
the cables would just hang there, side by side, until you threw the juice to them and then they would jump straight up and over so that they were 180 degrees apart and as far away from eachother as possible.
It was fun to watch.
