[moderator edit] this thread has been split-off from another thread (seen in titles below)
This thread is about the general subject of resistance soldering bus-strips onto cells, regardless of whether the busses are copper, nickel, or nickel-plated copper. Resistance soldering refers to passing electricity through two parts to get them hot enough to melt solder. There is a wide variety of formats to use for RS, but 3V and 40A is our initial target that has proven to be workable. Voltages between 2V and 12V are all feasible, but the heat of 40A is the most important factor. A key reason RS is of interest is that...the thicker you make the copper bus, The ability to make a connection with RS does not get worse, it remains the same (using copper is problematic for spot-welding, and the thicker the copper, the worse it is).

could you please post some pictures of the welder and packs you have built with this technique?
