The media could not be loaded.I really like this thing. I have never used one before and have only had about 10 – 12 practice spot welds before I made the attached video. As you can see, I haven’t quite gotten over being a little scared of the sparks. The build quality seems exceptional though I have nothing to compare to yet. The weld quality seems to match factory specs for battery packs I’ve tourn down in the past and requires pliers to fully remove. It is easy to use just pick a power level and press it to the metal for a sec and then it does its thing. I’ve messed around with it for a bit and the battery is still at 100% I can’t imagen any home project would require more than one charge. It came with some nickel foil and it seems like the foil itself is very affordable if you do a lot of battery repair you might want to pick up a roll or two. The welds themselves are very functional and hold up well while being clean due to granular power control. I didn’t notice any waste heat at all the device seems to stay cool after a few spot welds.
