    Excellent product for this price! Guess I'll order another one soon. I saw some of you have issues with welding quality. I will teach you two tricks to have perfect welds. 1. The first trick is to grind the weld pins, check the images. 2. The second trick is, DON'T APPLY FORCE when welding. You just have to be sure the nickel touches the battery, put one pin on the nickel strip and with the second pin just touch the strip and wait for the weld. Note: if you don't use the device for 5 days, it will automatically discharge the battery.

    Mini spot welder for making battery pack of 18659 cells. Teardown: https://youtu.be/WjJXhLWO9pM This spot welder comes with a 4300 mAh li-poly battery, which can deliver current up to 600 A. It has a type-c USB port for charging. This spot works in two modes: Automatic and timing mode. In automatic mode, this welder turns on after 1 sec when touching the nickel strip and in timing mode, it turns automatically on every 1.5 seconds for 1 sec. Timing mode is useful for continuous welding and automatic mode is suitable for a few welds. We test this welder over a large number of Li-ion and AA cells. The welding quality is very good and strong and stable. We will recommend this product. his spot welder has two Lithium-polymer batteries of 2150 mAh each, which can deliver up to 600 Amperes of current. There is a small microcontroller inside this unit that drives the combination of 4 MOSFET to deliver the current to the welding probes. And also, there is a tiny IC for charging batteries inside this Mini module. Working on this Mini spot battery is very simple. Current from the batteries is modulated by MOSFET with the help of a microcontroller. This high current is then fed to the welding Probes, which has very small resistance as compared to nickel. When heavy current passes through these probes to the Nickel, Nickel melts up and because of the small pressure from the probe tip, the nickel beneath the probes melts and penetrate inside the bottom metal. This makes the welding. Welding strength depends upon how far the nickel is penetrated inside the material which depends upon the welding current, nickel ate thickness and bottom metal type.

    The item arrived with completely discharged batteries, this is not good for the life of the batteries themselves, the product has conducting current bars in brass, not copper, the description is not true, however after charging the batteries it seems to work properly in the next few weeks I will do some tests on the current delivered

    V sobotu objednáno a v úterý přivezlo GLS. Přišla vybitá. Musel jsem nabít. Funguje dokonale. Hned jsem testnul na baterii Cr2032. Viz foto. Návod se dá stáhnout, ale kouknul jsem na video. Použil jsem body a vyšla mě na cca 1000,-Kč.

    Very fast shipment and good quality.Made some test welds and this device has a big punch already on level 2 of power. The leads are little short but managable; they are insulated with clear silicone tubing on the copper part! Arrived with manual in chinese only. I used the instructions in item description above and they are on spot. Arrived with 4m 0.1x8mm nickel strip.

    Thought it was faulty first sinne batteries came discharged. Took a few hours to charge it up fully and now works like a charm om the 0.1mm nickel strip included. Going to try a build of battery pack with 0.15mm nickel, also grinding abit on the copper pins as stated by another reviewer. All in all it does what it says!
