Don't throw away that broken amplifier, let me turn it into a useful tool.

I Turned an Old Amplifier into a Powerful DIY Spot Welder! What if an old amplifier that everyone considered electronic waste could become a powerful battery spot welder? In this video, I show the complete process of transforming an old, broken amplifier into a homemade spot welding machine capable of welding 18650 battery cells. Instead of throwing the amplifier away, I salvaged its transformer and useful electronic components, redesigned the circuit, built a custom welding controller, and assembled everything into a practical DIY tool. You'll see every step of the project—from dismantling the amplifier, selecting the transformer, modifying the wiring, building the control circuit, making the welding electrodes, testing the output, and finally welding real battery cells. This project is perfect for DIY enthusiasts, electronics hobbyists, battery pack builders, and anyone who enjoys giving old electronics a second life. 🔥 In this video: Salvaging an old amplifier Reusing the powerful transformer Building a DIY spot welder from scratch Homemade copper welding electrodes Electronics assembly and wiring Testing welding performance on 18650 battery cells Final results and practical demonstration If you enjoy DIY electronics, upcycling projects, homemade tools, and creative engineering, don't forget to LIKE, SUBSCRIBE, and turn on notifications so you won't miss future builds! 💬 Have you ever built your own spot welder?
