Arduino Based Spot Welders
The summer of weird and nerdy electronics projects continues… Lately, I’ve been using a lot of 18650 based Li-Ion battery packs in 2, 3, and 4s. As such, I’m thinking I need a battery spot welder. It seems as though a lot of guys prefer the Arduino based DIY kits and I was wondering if anyone had any experience with these. The most popular seems to be from Germany, but there are others… Anyone have any experience with this? If so, I could use some guidance! See Comments on the forum.
