Spot welder with pulse control

thingiverse

Here's my spot welder designed around a high power transformer from a microwave. I've taken a lot of inspiration from a similar project by Jim Conner: https://www.thingiverse.com/thing:2429361 But I've created both the model and the code from scratch. ### BOM with the pieces I've used (affiliate links): * Nokia LCD: [link](http://s.click.aliexpress.com/e/jcExxdA) * Encoder: [link](http://s.click.aliexpress.com/e/b7qymdI0) * IEC Socket: [link](http://s.click.aliexpress.com/e/bjmNUeFW) * Fuse holder: [link](http://s.click.aliexpress.com/e/cVYlxG12) * Jack connector: [link](http://s.click.aliexpress.com/e/cNwdkLRw) * SSR: [link](http://s.click.aliexpress.com/e/b16Vhztm) * 5V PSU: [link](http://s.click.aliexpress.com/e/cP9Sz8XO) * Arduino Nano: [link](http://s.click.aliexpress.com/e/ciwl9qeU) Arduino code is available here: https://github.com/krzmazur1/spot_welder/ Like my work? <link href="https://fonts.googleapis.com/css?family=Cookie" rel="stylesheet"> <a class="bmc-button" target="_blank" href="https://www.buymeacoffee.com/krzmazur1"> <img src="https://www.buymeacoffee.com/assets/img/BMC-btn-logo.svg" alt="Buy me a Beer!"> <span style="margin-left:5px">Buy me a Beer!</span> </a>
