Spot Welder, Upgraded 11000mAh Battery Spot Welder with LCD Screen, 80 Gears Portable Mini Spot Welder with Long Spot Welding Pen, Nickel Tapeand USB Charging

Muy buen producto. Como se especifica en la descripción

Excelente

Did one battery pack, welds were mediocre and barely penetrated 0.1mm strips. Pulled off with a small tug. Did the second pack and the unit quit responding. Pushed the pedal and nothing but a red blinking light. Took the cover off and exposed a D6 blue light flashing when I pushed the pedal. Unit is charged and showing 8.45V. Would return if I weren’t already outside of the window.

I was successful in using this product to weld 0.1mm nickel strips to 18650 batteries. I put the dial at 6/10 and it had plenty of power, so it could probably handle 0.15mm without much issue. The cable for the foot pedal is a little short but I was still able to use it.

The unit is working on strips until 0.15mm thick. Have just 2 LI-ION cells inside 4500mah connected in 2S configuration, and they can not deliver the advertised Amperage.

It worked when it arrived. After time in storage would start charging and then beep after a few minutes. Found some videos about repairing 11000mah battery spot welder. Disassembly is not easy. Remove the end caps, the main board is shimmed to fit against the case with aluminum pieces in grooves. The aluminum pieces need to be pulled out without damaging the board or pouch batteries. Remove sticky foam holding the batteries in place. Carefully move the board away from front so the welding contacts come out of the holes in case. The battery voltage when it wouldn't charge was .996V. Using an external power supply applied 3V with current limit 0.5A until battery was about 2V. The video said not to charge the batteries were discharged, but the batteries showed no sign of any swelling. This seemed enough for the onboard circuit to start charging. At 3.4V it still shows 1 blinking square for battery, and shuts off with low battery! No longer offered by original seller but there are some offered by Seesii and Amazon resale.

I have two favorite, but old Ingersol Rand NiCd tools that I have not been able to use due to the battery packs being bad. I have taken these battery packs to Batteries Plus to be rebuilt more than once, but each time with the same result, which is lack of power and doesn't hold a charge long. I disassembled one and found they used very cheap cells in the rebuild. Tired of giving my money away for no practical exchange, I decided to purchase this spot welder and try my own hand at it. With some good cells also purchased through Amazon, I rebuilt two of my packs. I did this after work in two consecutive evenings. I am ecstatic over the results. I have missed being able to reliably use these tools in my job. the welder performed flawlessly. I will say though, if there was one thing I could change, it would be to make the leads longer, as their current length makes some of the work awkward.

I was not expecting the quality or longevity of this device. On a 4sx40p battery build it did the whole thing in one go without recharging and with good solid spot welds (gear 4, 2 second delay). I used 0.1mm nickel strips. It still reads 100% battery.
