I know it’s been a very long while since I’ve posted anything on this thread, I’ve found a bit more detail on the robotic welder I found and posted in this thread. The video that gives some greater details is here.

From the video thee CNC seemed to be a Millennium series, and seemed far less crude than the welder from a year previous. The software seems to be largely complete as well. The welder itself was based off a TIG stick welder with a circuit to measure current to keep it from bursting through the cell with too much power. They also seem to have access to a Laser cutter, so they can cut out their own copper sheets. I even heard something about an ePassat on Siwastaja’s github but that was over a year ago.
Edit-
Also after looking more closely at the video, I could see that the CNC was labeled as an Asymtek Millennium, which after further research seems to be an automated dispenser, though I can’t tell what model the machine is from the video. Again it’s perfectly capable of welding copper, and the pack being welded is made of 52 29e cells for an ebike.
Any further thoughts on the welder? Based on what’s I’ve found for the cost of the cnc it wouldn’t be an inexpensive endeavor to replicate, though the software is freely open on github. Cheapest I’ve seen was just north of 3000 US dollars on eBay.
