In this project I will be showing you how to create a crude but functional battery spot welder. Its mains power source is a car battery and all of its components combined cost around 90€ which makes this setup pretty low cost. So sit back and learn how to build your own with an Arduino and a few complementary components. Let's get started!

Step 1: Watch the Video!

The video gives you all the information you need to create your own battery spot welder. During the next steps though I will present you some additional information.

Step 2: Buy Your Components!

Step 3: Build the Circuit and Upload the Code!

Here you can find all information about the circuit and the code for the project. Feel free to use it.

Also make sure to download the Adafruit SSD1306 library before uploading the code to the Arduino: https://github.com/adafruit/Adafruit_SSD1306

Step 4: Do the Power Wiring!

You can get all the components for the power wiring in your next home improvement store. Use my provided pictures as a reference.

Step 5: Success!

You did it! You just made your own crude battery spot welder!
