If you know what you are getting. Reading description it is 99...% Copper, Aluminum paper and Copper Foil Shielding Tape with Double-sided conductive adhesive all at same time.

Would this be a good option? It's 0.1x200x1000mm, which I could easily cut down into 100- 0.1x10mm strips for spot welding. Thoughts?

P.S. 0.1mm is nice gauge, it is easy to cut with Manual Guillotine Paper Cutter, any thicker and it gets difficult. Also note, copper oxidises and it can be randomly triggered, moisture, contamination, galvanic reaction.

I put a good amount of work into it, so please give credit and keep my contact on there if you modify it. And distribute this read only link.

Make sure you update the blue values to match your setup. Green values i carefully tweaked based on lots of testing and data... but if your setup is different keep that in mind
One could tweak it to work with a cap welder (hint, major change in the % peak current column is needed - you need to account for the falling voltage of the capacitors based on coulombs discharged) let me know if you need help with that. I spent about 15 minutes giving it a start... added calculated voltage drop @ the cap, now you need to use this to compensate for new voltage and how it will affect the current slew rate and peak current ...
Nobuo can you put in OP?
Would like to see someone develop it more for a cap welder.
