DIY Spot Welder Set Mini 100-200A for 18650/26650/32650 Lithium

Description:

It is portable, stable and reliable with complete tools, you can operate it yourself, suitable for DIY enthusiasts.
According to different configurations, the thickness of nickel pieces can be about 0.1MM-0.15mm.
This circuit with a 12V battery will become an energy storage spot welding machine for welding such as lithium batteries and nickel-chromium batteries.
This spot welder circuit board can be used for welding lithium batteries such as 18650/26650/32650.Battery with large discharge current will directly affect the welding effect.
Recommended Batteries:Lead acid batteries with good performance and low internal resistance (internal resistance less than 10 milliohms, discharge current greater than 100A), 36-45ah, such as new car starting battery; 4000mAh 35C-8000mAh 30C 3S model lithium battery pack; 30-35Ah capacity model 18650 battery pack.
