Spot Welder, Kerpu Mini Spot Welder, Portable Spot Welder Machine, Spot Welding Equipment Energy Storage 5000mAh for DIY 18650 Battery, Portable Battery Welder with Type-C Port (Black)

I recently used a battery spot welder, and overall, it’s been excellent! The initial instructions were a bit confusing, but with a few helpful YouTube videos, I quickly got the hang of it.I used this spot welder to replace batteries that had a coating making it impossible to solder to the sides. The spot welder worked perfectly for this task, allowing me to make strong, clean welds with ease.Once I figured out how to use it, the performance was fantastic. It made the battery replacement process much smoother and more efficient than soldering.Overall, I’d give this battery spot welder five stars. With a bit of guidance from online resources, it’s a reliable tool that gets the job done effectively.

Works perfectly. It’s a little tricky to hold the probs and the hit the weld button. But it does have an automatic mode. Once you get used to it.

This product is really handy and definitely value for money, you just need to be aware that it won't do thick nickel strip. Works well about 0.15mm and you would be pushing to do 0.18mm. I also give it a rest now and then as the leads get quite warm. I will normally do about 30 spot welds and then have a break for 5-10mins before going again.

Esperé ansioso este para soldar unas baterías que estoy haciendo, el empaque agradable y un manual sencillo, para un dispositivo así no hace falta mucha explicación pero no funcionó. Ni siquiera enciende un led, totalmente muerto incluso después de tenerlo más de una hora intentando darle carga donde tampoco dio indicios de estarlo haciendo.Intentaría la devolución del artículo pero personalmente no me es factible hacerlo.Actualización.Inicialmente esta fue mi reseña pero enseguida el vendedor se puso en contacto conmigo dispuesto a enviarme un equipo nuevo y recomendando al fabricante una revisión de calidad más exhaustiva. Por políticas de Amazon no debo aceptar la propuesta y personalmente no hago una crítica para tomar ventajas pero si puedo ser sincero y reconocer que estas cosas pasan y si bien mi experiencia con el equipo fue mala las respuestas del vendedor son de primer nivel por lo que no dudaría en darle a este la mejor calificación.2da actualización. Finalmente he recibido el nuevo soldador, llegó con un 50 porciento de carga y pude hacer una sencilla prueba para verificar que funcionaba correctamente.Después de cargarlo totalmente he podido comprobar que este soldador se ajusta estrictamente a la descripción y utilizándolo bien creo que rinde más que lo que dice el fabricante.No tengo un trabajo específico que hacer en este momento pero me ha gustado tanto el desempeño de este soldador que he decidido preparar una muestra en video de todos los modos de funcionamiento como demostración para su utilización. La verdad, LO RECOMIENDO encarecidamente, es fenomenal tener un dispositivo como este y le aseguro que de verdad hace el trabajo.Por estos motivos y los que explicaré después he decidido ser justo otorgando la mejor calificación a este equipo así como a la atención al cliente que no pudo ser más rápida y eficiente.

I bought this a few years ago back when it had 6 "gears". It worked ok back then but was underpowered. I think I used it a total of 2 times back then. I went to go use it again and it now no longer has enough power to weld even the thinnest nickel strips. now I have to buy another one that is more powerful and not cheap garbage. This isn't even high enough quality for a hobbyist that uses it every once in a while, because now 3 years later it is completely useless... it is complete trash that will just disappoint you over and over again. you know what they say, you get what you pay for.Also important to note: It will NOT weld pure nickel strips at all, the only thin I have been able to weld with it is the fake "nickel" strips that come with the welder. I bought separately some 0.1x8mm nickel strips (the thinnest kind that even the weakest welders should be able to weld) and it can't weld them unless you hit the same spot 3 times.

I read other people's reviews and I was a little scared. But, I bought it anyway. I love it! It has worked great for me. I have been using .1mm nickel strips on setting 3, for 18650 batteries, and it works great. I have not used the thicker .2mm strips that were supplied with the unit. I thought there would be a loud "pop" like I was TIG welding or something. Nope. Very small flash and a small puff of smoke. This is great for hobbyists like myself that don't like to see electronics (laptop batteries, handheld radios, vape pens, etc.) go to waste because of dead batteries. If you have a need for a light duty spot welder, I recommend this one!
