  • Works well, no complaints
I've been using a battery tab welder that I cobbled together from an off-the-shelf board and a LiFePO4 race car battery (RIP my race car). It worked "well enough" but I wanted to see what a properly engineered, pre-packaged solution was like. Okay, so, this is much better than my cobbled-together solution. It's really hard to explain the difference, except to say that this welder is just easier to get a good weld. Using my 14v battery solution, I sometimes get what I describe as an "arc blowout", where electricity arcs an air gap instead of passing entirely through the electrodes and nickel strips. This is likely partly due to settings needing to be tuned. However, with this product, it just worked perfectly out of the box. I used the included 0.1mm strips, as well as the 0.2mm strip I had on my bench and it's really hard to get a bad weld (within reason, of course). The neoprene(?) foam insulation for the electrodes is super nice as repeated welds cause them to get uncomfortably hot (the same happens to my home-brewed solution). Because I can't leave any warranty intact, I went ahead and pulled it apart to have a look inside. The case houses a pair of large capacitors connected to the front panel and controller board with nice big conductors. There's also a power management board that looks well-assembled (though I'm not an electronics engineer so I can't say if it's well-designed). I have a DC clamp ammeter but the sampling rate isn't high enough to get reliable results. After numerous attempts, the max current I saw at the highest setting was 270A. ... show more

  • DOCREATE
La unidad trabaja muy bien , solo que la fuente que alimenta al equipo creo q puede ser mejorada , debido a q note q con solo unos cuantos usos de solo 5 a 10 minutos se calentaba en exceso

  • nice tool
I own multiple battery-powered spot welders, but this Dual Farad Battery Spot Welder is by far the most efficient, safe, and high-quality one I've used. It feels like a professional-grade tool with excellent build quality. The package includes the spot welder, two welding pens, a foot pedal switch, a power adapter, nickel strip samples, and a user manual. The compact black body, combined with a 1.8-inch LCD display, gives it a sleek, high-tech look. The 3000F dual farad capacitor is the real star here, supporting 25 adjustable power levels for 0.1-0.3mm nickel strip welding. The foot pedal and auto-mode options immediately caught my attention. I tested it on an 18650 battery pack. Once powered on, the LCD screen displayed the default settings, including power level (1) and capacitor voltage. Adjusting the power with the dial was smooth,I set it to level 8 for 0.2mm nickel strips and tried auto mode. Placing the welding pens on the strip and applying slight pressure, the machine instantly detected contact and fired a precise pulse, creating strong, clean welds that wouldn’t budge. No burn-through, no weak joints,just solid, reliable results. Switching to foot pedal mode, I connected the pedal and controlled the welds manually. This method is ideal for continuous welding, and I completed 20 welds in a row effortlessly. The 25-level adjustment allowed me to fine-tune the power for different materials: Level 5 worked perfectly for 0.15mm pure nickel strips Level 15 handled 0.3mm strips with no issues The LCD display clearly showed real-time settings and capacitor voltage, making adjustments quick and precise. I’m really impressed with the welding pens,they have thick, high-quality wires that handle high currents with ease. The pure copper tips are sturdy and smooth, ensuring consistent performance. Even after dozens of welds, there was only minimal wear, and the rubber grip prevented overheating. Despite its powerful performance, this spot welder is lightweight and easy to carry, making it convenient for various work locations. The dual-mode operation is well thought out,auto mode is great for quick jobs, while foot pedal mode offers more precision and control. After about an hour of continuous use, the power adapter gets noticeably warm. While not a dealbreaker, it’s something to keep an eye on. ... show more

  • Died, expensive mistake
Died after a couple of spot welds, started to smoke, and couldn't get the manual or automatic mode to function.

  • Impressive Spot Welder with a Minor Flaw
This spot welder really impressed me. I had never used one before, and I ordered it not specifically for battery work but for connecting thin metal strips in model building and small mechanical toy projects. I tested it on the steel-plated strips included in the kit, and it worked very well. (I’m not sure why people refer to these as nickel strips—they're clearly steel with a nickel coating.) The only issue I found was with one of the terminals. The collet shaft at the end of one of the copper tubes wasn’t crimped properly and slid out when I tightened the copper needle. This should have been caught in quality control, but overall, the tool performs as expected. ... show more

  • Spot Welder
This review is for “ Dual Farad Battery Spot Welder, 3000F Capacitor with 25 Gears Adjustment,Portable Spot Welder for 0.1-0.3mm Nickle Strip Welding,with 1.8'' LCD Display” It works as expected. We don’t use it on batteries but on little crafty type things. It’s easy to use and seems well built to my untrained eye. We haven’t used it extensively but so far so good and if that changes I will update this review. ... show more

  • Worth buying if you make your own battery packs.
Has all the power needed to blast through nickel strips instead of welding if you crank it all the way up. Super easy to use, the included pedal did not work. In auto mode the timing is adjustable and works how I prefer anyways. Setup is easy and the included electrodes are durable and firm. The power supply gets warm when performing continous welds. I'm expecting it to fail before the tab welder. ... show more
