Hi everyone!

In this video I decided to show you have I made this simple and cheap spot welder which is a highly useful tool for a DIY'er that can be used in many different projects for creating rechargeable battery packs! Nowadays, lithium batteries are widely using in the electronic products, rechargeable batteries, electric vehicles, balance vehicles, aircraft models, ship models, electronic tools and so on. I am using a microwave oven transformer that I have salvaged a while ago. I also compare my DIY spot welder to a $200+ Mini Intelligent DIY Spot Welder OLED Automatic&Manual Switching Lithium Battery Power Battery Pack Welding Machine SQSW1.

Hope you give this project a try! ✌
