This is a DIY version Spot Welding Machine that can be used for welding 18650/26650/32650 and other lithium batteries. You need your own 12V battery for the power supply. It is easy to weld the common 0.1mm-0.15mm nickel-plated sheet. The battery needs to have a current greater than 100A, to be able to do the proper welding.

Power supply voltage: 11.5V-14.8V
