I have read both threads on home made and reasonably priced spot welding machines. But I could not find the working technical aspect for them. The following questions are specific to spot welding small cylindrical battery cells (18650 and 26650).
1) What is the optimal voltage at the tip of the electrodes? 3V, 5V, or what?
2) What is the optimal current? 50A, 100A, or what?
3) What is the optimal time for the above two? 0.5 second, 1 seconds, 2 seconds, or what?
4) What is the optimal distance between the 2 electrode? 2mm, 3mm?
I looked up in Wikipedia too, but could not find any specific values.

Thanks.
