KkMoon 5000 spotwelder low welding power repair. Dangerous welding cable routing. Bad soldering.

Тәжірибелік нұсқаулар және стиль

My three months old september 2021 KkMoon welder showed poor spot welding. (Aliexpress) seller showed little interest in solving this problem. I opened the case and found two extremely bad soldered contacts. I also discovered that one of the two welding cables could break the battery tabs which may result in a Lithium fire. Video shows how I solved these problems.

    Not bad: Thanks Oldtimer. It is true what they say: "They don't make them like they used to"

    Infelizmente só se descobre as falhas usando o equipamento. Adquiri o equipamento recentemente mas ainda não fiz nenhum serviço. Deixei de importar outra marca da China pelo receio do custo de importação adotado neste momento pelo governo atual, optando por comprar essa máquina por aqui mesmo para fazer modificação em minhas parafusadeiras com baterias 18650. Fiz um simples teste e me senti satisfeito com o resultado. Vamos ver futuramente. Obrigado pelo aviso.

    Oei, heb net zo iets besteld. Ander merk maar wellicht dezelfde fabriek en kwaliteit. Zal m gelijk open maken om te kijken wat de stand van zaken is. Heel nuttig filmpje, bedankt!

    I believe those run soft cells inside the machine. First job with the welder I figured should be to build a better battery with the unit for itself .my plan anyways when I get it in.😊

    Bedankt! Heb die van mij gelijk open gemaakt en verbeteringen aangebracht. Ik heb ook gaatjes in de behuizing geboord en er een pc ventilator opgebouwd om extra te koelen. Uiteindelijk moest ik hem 8x opladen om mijn 52v ebike batterij met 70 cellen te puntlassen maar het is gelukt en hij doet het nog. Voltage heb ik niet onder 7,5v laten zakken I.v.m. doorbranden mosfets bij te lage voltages

    Ventilator(tje). Dat lijkt me inderdaad een hele goede toevoeging! Ik heb er tot nu toe alleen 18v accu’s mee gelast en dan werden de kabels en laspennen al heet. Intern zal dat niet anders zijn dus geforceerde koeling zal zeker effectief zien. Gerard

    Very informative, thanks for you uploads on spotwelding. I'm curious how the kkmoon has lasted after your repairs. Do you still use it? Thanks

    Yes. It is working correctly now. But I would have bought a non-Chinese welder now despite the fact that they are twice as expensive.

    Wow that's scary, I just bought this machine. Btw, for metal plated nickel sheets (0.15mm), which level setting would you recommend for 18650 cells? 7 or 8 perhaps?

    what size thickness of nickel stript is suitable for 18650 batteries

    Depends on how much current the batteries need to supply! For lighting purposes (low current needed) 0.10 is sufficient. For applications where high currents may flow (e.g. jumpstarters for cars but also ebike batteries) the thicker the better! Then the capacity of the spot welder comes into play. With the KKMoon don’t try thicker than 0.20 mm. A larger strip 10 mm in stead of 8 or doubling the strips will help too! Gerard
