Spot welding machine accessories, soldering pen complete set of accessories DIY portable 12V battery energy storage spot welding machine PCB circuit board
Used for welding lithium batteries such as 18650/26650/32650, with advantages of portability, stability, reliability, and durability.
Users need to bring their own 12V battery for power supply, with a welding current of about 90A~150A. They can easily weld common 0.1mm~0.12mm nickel plated sheets. After several generations of product updates, it has now been upgraded to automatically trigger welding, freeing the fingers of buttons.
System voltage: 12V-14.6V
Working current: 90-150A
Battery recommendation:
A lead-acid battery with good performance and low internal resistance at 20-45ah
3.5-5.5ah 3S aviation model lithium battery pack at around 45C
30-35ah capacity 18650 battery pack
The battery pack that can start the car can basically meet the power supply needs of this circuit
