Well, I pulled apart the "broken" welder today and measured the voltage of the battery at 2.0v. Couldn't get it to charge when plugged into the USB C charger.

Tried using my multipurpose hobby charger to charge it, but it complained that the voltage was too low.

Used my switching power supply to bring voltage up enough to where my hobby charger would charge, and then boosted until the regular onboard USB charger would take over.

Unit is as good as ever, which isn't great. Doesn't make good welds. Good chance it's the operator.
