DIY Battery Portable PCB Board and Spot Welding Pen Set Electronic Energy Storage Spot Welding Machine Accessory ( Item#: E10941 )

This is a set of spot welding PCB board and spot welding pen set. Uses this circuit board to works with a 12V battery can makes it become an energy storage spot welding tol for welding nickel pieces such as lithium batteries and nickel-chromium batteries. The spot welding pen is consist of silicone wire and copper solder pen, safe and can  provided stable performance. And the welding thickness is range from 0.1mm to 0.15mm according to different configuration, for welding 18650/26650/32650, etc. You can have a try.
