Make Spot Welder 500A | JLCPCB
This video tutorial demonstrates how to build a cost-effective, powerful lithium battery cell welder using a car battery, with dual pulse support and open-source resources for PCB and PCBA ordering.
MAIN POINTS FROM TRANSCRIPT
- The cell welder is compact, powerful, and inexpensive to build.
- It requires a car battery or lithium batteries, without needing a transformer or super capacitor.
- Dual pulse support ensures strong, clean welds on nickel strips.
- The project is open source, with resources available for PCB and PCBA ordering.
TAKEAWAYS
- Reuse components from old devices to reduce costs.
- A high discharge battery and six MOSFETs are key to the welder's function.
- Proper soldering technique is crucial to avoid damaging MOSFETs.
- JLCPCB sponsors the PCB, with a tutorial available for ordering assistance.
