Battery Spot Welder, AWithZ Handheld Spot Welder 11 Gear Adjustable, Automatic and Manual Modes Battery Welder for 18650 Battery, Welding Nickel Sheets, Iron (Black-H1)

Well, bought it to see if I could weld some contacts to 18650 cells. And guess what: It works great! Turn it on by pressing the button for 2 seconds, set your power (power level 2 sees *fine*), touch the probes to the metal and battery end, press down, and spark: They're connected. Do it again for 4 points and you're done....So yeah, great little device, simple to use, no problem.

Ideal for Repairing TooI purchased this spot welder specifically to repair some tool batteries, and it’s perfect for the job! The 11 adjustable gears give you great control, allowing you to fine-tune the settings depending on the materials you're working with. Both the automatic and manual modes are easy to use, which adds versatility depending on the project at hand.It’s compact but powerful, and it works flawlessly for welding nickel sheets to batteries. The build quality feels solid, and the 2M of included nickel is a nice bonus. If you're doing battery repairs or small welding projects, this tool is a great addition to your workshop!l Batteries with Precision

Works great! DOES NOT WORK ON 0.2mm STRIP, highest energy setting was dimpling the metal but not nearly hard enough to weld. Never used a battery spot welder before this. Very easy to use. Bought for rebuilding a M18 5ah battery pack, and it holds just enough charge to comfortably do all the spot welding needed on one battery pack. It charges "quickly". I'd recommend using some light scotchbrite pad every few welds to clean the electrode tips.

Ordered one, got it in the mail next day. Would not turn on, thought the battery was dead so I used the charging cord that came with it let it sit over night, still wont turn on. Ordered a replacement and got it next day. 2nd one turned on right away and I welded 2 16650 batteries together, went to weld a 3rd battery and all the lights flashed on it and it shut off. connected to the charger let it sit and it wont turn on either. returning both. DO NOT BUY

I had some issues with the first order I got, but it wasn’t with the product the spot welder works great, I didn’t get everything that was supposed to be to come with the welder! I reached out to the sender and went above and beyond and replaced what was missing from my order!!!Great company! Amazing product!!!

This is what I learned after putting together 60 batteries. This welder is good, but it has to be on its terms. First, don't use this on tabbed batteries. That was a mistake. The tabs are thicker than the included nickel strip and the welder will have about a 50% success rate and welds break with the slightest mechanical movement. If you have tabbed batteries, cut the tabs off. The nickel strip included is perfect. Get more of that. Second, I noticed you get about 4 really good welds before needing to wait a minute. Seriously, once I learned to use this with a 60 second timer, things went a lot smoother. Third, the instructions will get you basic button operation, nothing more. Watch some videos if you never used one before. Once I learned about the tab problems and required time delays, I came to appreciate this little welder.

I was surprised at how easily this worked. I used it to replace the expended batteries in cordless battery packs. It made it very easy.I would highly recommend this.

The media could not be loaded. UPDATE: JULY 30, 2024 - Dead! No longer takes a charge, will not turn on. 10-sec reset had no impact. Worked well while it lived, but it did not live long. I took it apart. The battery has 3.8v (4.2v max according to the manual) but there is no one is home (no lights). Nothing looks fried or disconnected... just DEAD!The first welder I received was a total failure. It was totally dead on arrival, charged in 30 mins, died in 5 minutes and never produced a single weld in any “gear”... just BEEPED. It would not work, even when plugged into a 2 amp USB power source.I requested a replacement, which Amazon sent promptly. I left the new welder on charge overnight, just to be sure.While there are some apparent quality issues, it seems solidly built and is easy to use. I have only made one NiCD battery pack using 4, 1/3 AA cells. It worked very well and made 12 welds without need to recharge. It does the job. The attached video is just an example.
