I got mine from HTP When I bought the welder, it was pretty expensive, and I think it was about $250 that was about 12 years ago. The entire time I thought it was solar power until it stopped working last year, then I found out it had batteries. Those batteries must have been pretty good to last that long. Even with the new batteries it doesn’t work to good anymore, maybe they only last for so long even though I don’t use it that much.
