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

Excellent product for welding battery packs. Sorry no video, but I repaired an $80 taser x26 battery which uses two cr123a batteries. Easy to use. Small and effective. I saved over $50 by buying this product.

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.

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

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.

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.

This little spot welder was a good choice, it has more than enough power, it’s compact and easy to use. It is made with quality materials and the battery life is great.

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.
