Ask yourself. ’ DO I HAVE THE NECESSARY SET UP HERE IN MY DIY HOBBY SHOP TO PRETEND I CAN WORK IN THAT WORLD?”

I am sure the answer is NO !

Unno. When I used to spot-weld sub-C NiCd cells, I’d take a thin strip of metal, put a dimple in it where I’d want the weld to be, securely have one contact go right to the cell, and the other end to the tin strip. Carefully lower it down into place, and ❋pouf!❋, the arc would weld that critter tight.

Used a few of beefy caps, like 80,000µF power-supply caps with screw terminals, in parallel, with ~14ga wire coming together at the “probes”.

Was enough to “stick” a screwdriver to whatever it’d touch, so…

Exactly, we aren’t building automobiles or aircraft here. It’s not rocket science to spot weld a tab on a battery.
