Description of 🔋 U.S. Solid Battery Spot Welder with Capacitor Energy Storage – 11.6 KW Mini Portable Spot Welding Equipment feat. 70A Welding Pen for 18650, 14500 Lithium Battery Pack Building

The newly designed U.S. Solid battery spot welder is equipped with two super capacitors for energy storage and power supply for pulse welding. Compared to a traditional AC spot welder, it does not interfere with the electric circuit, which means no more tripping problems. The machine’s super energy-gathered pulse technology combines with a max welding power of 11.6 KW to provide a reliable welding effect. The welder’s small size and light weight make it more portable compared to a bulky traditional spot welder. The aluminum alloy housing also provides a more powerful and reliable machine. Equipped with the 70A separated-style spot welding pen and ‘AT’ automatic welding mode, this machine allows you to work easily and efficiently. The low power consumption technology enables you to use the machine efficiently for 12 hours with no heating problems. The pulse welding power can be seen on the LED screen and set via two adjusting buttons(0-99 range). 0.3mm nickel plated and 0.25mm pure nickel can be easily welded with the 60 J max energy. Widely used in battery pack building&maintenance and common metal welding.

Didn't work for spot welder

Didn't work when delivered, company sent another replacement, didn't work either. But it's very easy to get a full refund

Pros
  • only. Well built
Cons
  • Update available

I do not recommend. Difficult to use. Not consistent.

Difficult to use. Spot seams either don't hold or burn through. Tried different settings and practiced with them, but only a few spot welds actually held up. To the contradictory.

Pros
  • Cool product
Cons
  • -

Not as strong as it says

This definitely doesn't even come close to the 0.2mm thick nickel I bought it for. Not even half. He made the smallest dent on pure nickel, 0.2mm thick. This is what you want to use for rechargeable batteries.

Pros
  • There's something to it
Cons
  • No mold required

Good product in the welding equipment category

Manufacturer's suggestion: supplied power pack with longer cable. For welding 0.15mm x 8mm nickel strip with 18650 this welder works quite well. According to the instructions, the first charge took 30 minutes. Immediately after making about 100 welds in 30 minutes, I varied the power from low to maximum. Welds look good and have never had power issues.

Pros
  • Useful not only for the intended purpose
Cons
  • Nervous

Basically no instructions, but it works!

This is probably best for people who know exactly what they are doing, although this is a low voltage welder there are many risks and precautions not covered in the instructions. I will say that after charging for 30 minutes it worked almost perfectly. Got a dozen quick welds with standard settings and nickel plated sheet metal. A good product for the price and so far so good!

Pros
  • Certified
Cons
  • Reliability

This is the BEST spot welder I've ever used

I've been doing a lot of research on battery technology and decided to build some batteries (for the couple of UPS's I use). I probably spend $500 a year on batteries for all the UPSs I have in the house, and LiFePO4 batteries can have a high initial cost, but over the long run these are the absolute best batteries for just about anything that uses a battery. I bought a couple of small spot welders off Amazon and only one was halfway decent but still not great. This spot welder works great…

Pros
  • Slim design
Cons
  • Neutral

Seems good for a newbie

I bought this to build 18650 packs. I've never spot welded before and thought about welding but really just wanted something finished. Charging took about 30 minutes. (as stated in the attached documentation) and it displayed the capacitor voltage all the time during charging. Once charged, I was able to increase and decrease the value of "t" using the buttons on the device. It doesn't look like I can set the current or time independently, but I think the value of t is probably sufficient. I…

Pros
  • Good thing
Cons
  • Protection
