So we know that people usually do 4 or 6 spots.
How many amps is 1 spot? I always thought 5 amps so if I’m pulling 30a from a cell, I do 6 spots. 3 clicks with my welder.
Does it matter if it’s nickel or copper nickel sandwhich?
If it’s too much to figure out, what’s the worst case? 5 amps per spot? 3amps?
Reason I’m asking is because I did 6 spots on my cells. I can pull 300a but my wires can only do 200a. If that’s the case, I’ll just replace or double my wires and start pulling 300a.
Most people go by 5amps per spot being a rule of thumb…
No idea if there is any science behind that number, but that’s the general consensus.
I see. Ok. Thank you.

The 5A per point number comes from some measurements about the diameter of a weld but it only applies on a good weld, a more reasonable number is 4A per negative side weld and 6A per positive because the extra thermal mass means negative end welds have a bigger heat affected zone but smaller region of diffusion
I just decided to go with 5A because 4A-6A is 5A. LOL.
Sometimes going 8 spots per side because P45B. LOL.
But I’m guessing it also changes with the material. Copper/Nickel Sandwich, I’m guessing would be able to handle more? Just to be on the safe side, I’ll say 7A per spot for copper.
