Battery Spot Welder, AWithZ Handheld Spot Welder 11 Gear Adjustable, Automatic and Manual Modes Battery Welder for 18650 Battery, Welding Nickel Sheets, Iron

I have only used this welder for few small jobs but it worked perfectly. Very precision and easy to control, Good price and I didnt have to charge it since I got it for about 10 jobs I have done.

I have tried the style of spot welder with a big battery pack and 2 long wires to the contacts, and yes, they work. This spot welder saved me an immense amount of time in rebuilding my DeWalt lithium batteries. Wow. Fast, easy, solid spot welds, and the battery lasted impressively. After 3 completed batteries, so 30 cells and 60+ connections of 4 welds each, this unit still had battery left and was functioning perfectly. It did get warm in the hand and I hit the thermal shutdown threshold once when I was working fast. It got warm (not hot) and stopped welding for a few minutes, cooled down and kept going. Not a big deal since I used the time to solder the balance leads on. So far I really like it would buy another if continuous production were an issue. Swapping between 2 of them could keep a person welding nickel strip all day.

As someone who frequently builds custom battery packs, I'm always on the lookout for tools that can speed up and simplify the assembly process. The AWithZ Handheld Spot Welder has become an invaluable tool in my workshop. This portable spot welder is lightweight and compact, making it easy to handle and position as needed. But don't let its size fool you - it delivers up to 400 amps of current to achieve strong, reliable nickel strip welds. The dual copper electrodes pressing from both sides helps ensure even contact and heat distribution. I've been consistently impressed with the quality of welds this little machine can produce. Welds form quickly and penetrate multiple layers of nickel strip. The built-in pulse time control lets you adjust duration to suit different thickness strips and battery types. One of my favorite features is the foot pedal control, which frees up both hands for positioning strips. The pedal gives you complete control over activating the pulse. There's also a convenient in-handle switch for hands-only operation. At its affordable price point, I think the AWithZ spot welder is a steal for anyone into battery building. The portability and effectiveness of this tool has sped up my pack assembly considerably. I can now easily weld packs with series connections on the go. I highly recommend it for battery enthusiasts, electricians, and hobbyists looking to expand their capabilities.

My unit was DOA. It doesn't turn on. It displays a charge indicator when I plug it in, but the power button doesn't do anything. Held it for two seconds, nothing. Held it for ten seconds to reset the device. Still nothing.

Worked.

Struggles to make a strong connection even on the highest setting. It will either burn a hole through or not even leave a mark. I've seen a lot of other reviews that say similar things. The only time it seems to have enough power is right after taking it off the charger.

I used it to replaced dead cells in a 20v impact wrench battery. I set power to 11 and weld cells together using included nickel strips. Original plates are too thick for this tool. Battery life is very good. It is enough to weld 5 cells without problems.

Simple ,reliable, the STD design has foot pedals cables ,power hook up .... This works with no cable issues and you can't accidentally damage it with bad alignment ...

Funciona bien, solo hay que entender bien las funciones que vienen en el manual

After shopping and reading reviews (all over 4 stars) I have decided to take a chance with this one… Bare in mind that I have only tested it for 3 welds on 18650 batteries Yet results are beyond expectations If you take a look on my actual images, not only the weld was strong using 0.2 pure nickel strip, it teared up the strip when I had to use pliers to take the battery off the strip, * using the highest gear (11) and respecting the recommended 45 degrees angle: I have yet to use it for several hours but so far everything points to a solid cheap option. Bought with my own money, not sponsored, in Quebec, Canada I will update if major flaws arises Cheers
