Plus those things seem to be far too powerful. 2.5KVA? That sounds like it's
designed for patching up damaged car bodywork and other similar tasks.
Running that much power through a battery tab will likely blast it to
smithereens.
I still haven't found anywhere that'll sell me a sheet (or a few offcuts) of
0.003" thick Ni200 or Ni201 nickel sheet besides McMaster-Carr, and I don't
think they ship across the pond anyway :-/

Later.
