hi...
i'm using the Arduino v2.2 spot welder, with 140ah battery (should be 1000amps) and 21 ms pulse time (2 pulses) trying to weld 0.2 nickel strips.
the welding always strong on the negative side, but but very weak on the positive one, not only that, the positive probe sticks very well to the nickel after welding, as you can see from the video

i also tried brand new probe and here you can see a comparison where on the left the used probe, and on the right the brand new one
and here you can see how it is after the one single weld
i believe the tip actually got stuck into the cell
so what could cause this?
