K99 Mini Automatic Spot Welder DIY Kit | DIY Electronics kit

The K99 Mini Automatic Spot Welder DIY Kit is a compact and practical solution for performing precision welding on battery tabs and nickel strips. It uses controlled pulse discharge to generate localized heat, allowing metal strips to bond without damaging sensitive battery cells.

This K99 Mini Spot Welder operates on a 12V DC supply, making it compatible with battery sources or DC power systems commonly used in electronics labs. The automatic trigger mechanism ensures consistent weld quality by delivering controlled pulses without requiring manual timing.

Designed with a PCB-based structure and optimized copper traces, the device efficiently handles high current bursts required for spot welding. It is particularly useful for assembling and repairing lithium battery packs used in robotics, drones, and portable electronics.

Available from StemVolt, this unit is suitable for students, hobbyists, and developers working on Mini Spot Welder for Battery applications and practical electronics projects.
