What power supply/battery are you using for your machine?

I showed the battery at very end of the video. Its 4s 35p sony vtc4 battery pack. Works much better than the car battery

I had grinded these practice cells, but shouldn't be a necessary. Just make sure its clean

@pajajaska I'm facing problem about spot welding copper strips with nickel. My copper strips do not weld on cells but get welded on nickel strip instead, is there anything wrong I'm doing?

@@Mr_Motor I think that you don't have powerful enough battery/powersupply or powerfull enough spot welding machine. What thickness nickel and copper you are using?

​@@Mr_Motor Im assuming that it does not have enough power to weld the copper. When I was using car battery as a power source for my spot welder it didn't weld copper well. Then I upgraded the battery and it welds good. Are you maxed out on your settings?
