Since many of the DIY battery builders are likely to have a few dozen spare 18650 cells, how likely is it that we can build a spot welder powered by these cells?
I have about 30 konion us18650vt cells, the high current variant, and these could potentially provide 10~11v at 300A in bursts, outputting this through a timer so we can achieve a good dual pulse weld, and run a dozen irfb4110 mosfet instead of the scr more commonly used, could we build a spot welder?
It seems a little far fetched, but I can't see why it doesn't have the potential to work, and potentially cheaper to build that a capacitive welder.
