I tried a junction between capacitor discharge welded bits: the junctions are sturdy enough, and generate, even with stainless 304 against ni-chrome - but I haven't got the time to take it any further. I was aiming to do it with gear you can find anywhere, and bits of stainless and bits of heating element seemed a good idea. Steve
