There are several types of spot welders, but the best for spot welding batteries is the capacitive discharge welder. The heart of the welder is a bank of six maxwell ultracapacitors , each rated to a whopping 650 farads, at 2.7v. Running six in series results in 108 farads at up to ~16v.

The advantages are repeatable energy delivery,and minimum heat effected zone. Building a portable solar powered spot welder: Schematics and printed circuit board for the spot welder

The adc input capacitance is 8pf, and the conversion rate is approx 100khz. You are correct, if the max starting current is 2 ka (the advised max is 1.9 ka for the bcap3000) and the cap pack resistance = minim. Find this pin and more on electronic gadgetsby ben holland.

Its specifications are matched to allow full load operation of welder and capacitor module (one weld of 50j every second), and therefore it is capable of delivering 80a at 8.1v. The one below shows the user welding a. It may, of course, differ, depending on what internal resistance of the welder you happen to achieve in your construction.
