Hi guys, I normally post on various Facebook groups but I was asked by several users to post on here. I have been prototyping a fuse wire welding attachment that I wanted to share. It's a concentric pin design, intended to make welding fuse wires to 18650 cells or nickel strip as easy as possible. My latest prototype is V1.4 and I'm finally happy enough with it to send out a few prototypes for testing. Questions, comments, criticism, and suggestions welcome. To be clear this is a prototype in development, and is NOT FOR SALE.
