Then there's cost reduction potential :-)
No way to clamp anything so you don't need all these precision parts?
Until the spot contact lets go at a not so good moment, or one of the panels to be welded had a bad spot there, or a cable breaks, and so on. Never assume things to remain as perfect as they are on paper or in the engineering lab.
Good! I'd test for faulty conditions as well, like the ones above.
If you live anywhere near high voltage power lines, be very afraid if they ever collapse. The induced voltages in length of cable are interesting.
I remember a report and a photo where some guy installed a cable TV hookup at a house near power lines. It cinged the whole side of the house.
Yes.
Nope. As I've said, it works without the groud lead even attched, or even on a bit of coax.
