Works perfectly and much more powerful than I expected

The lowest setting works great which means if I had to make thicker welds I would be fine. I tried the highest setting with some thicker nickel strips and they welded well too. Thanks very much!

Pros
  • Good product for the price
Cons
  • No

Very disappointed with welders and accessories

Open the box, charge it, turn it on 1 tried, set the power level to 2-3-4, still doesn't work discharged a little Put charger back, seems to work, not very durable seams, mostly poor performance, welding new batteries

Pros
  • Stylish and modern design
Cons
  • Functionality

Also advertised

I don't remember the exact numbers but I believe it was only designed for spot welding 0.15mm nickel strips and I bought 0.2 -mm nickel strips. As long as I kept it at the highest level it worked great and I didn't have to buy a thinner nickel and then wait for it to arrive. Good product. Sturdy (I've dropped it a couple of times) and for the size and money, I highly recommend it.

Pros
  • Very good value for money
Cons
  • Long delivery time

Works like a dream! What else can I say?

I ordered a welder with a pack of nickel strips to weld legs to CR927 Li-ion batteries. It got to ORD Airport from Hong Kong in less than 7 days, then spent a LONG time (20 days) in Grande Prairie, Texas, and then got into my sweaty little hands today (4/28/21) and all I did , was this press and hold the switch for about 2 seconds and it started beeping and I put the nickel sheet pieces on the CR927 coin changer and BOOM! Ready! I soldered them to the board and it works! I finally got my DS3231

Pros
  • Great price
Cons
  • Big and bulky

Not as strong as I was hoping

I was hoping it would make a 0.15mm thick strip but its performance isn't up to the mark. Welds a little, but it turns out a poor-quality seam. To be fair the description says it's 0.12mm so I was asking for a lot. But another user review showed that 0.2mm welded well at high power. The internal circuit board differs from the pictures. The physical layout is the same but the colors are different. Why does it matter? Well, confidence goes down when some things differ from what is pictured or…

Pros
  • Price
Cons
  • Minor things

Works just as hoped. at the moment

Just received a few days ago and connected to the charger. From the start there was ZERO sign of it being charged. There is no red charging indicator on the back, and the front lights do not light up, and pressing the button to turn on does not work. I left it charging at about 1/2 and still nothing. Ouch. What to do? Wondering if it was drawing current from the charger, I connected it via a USB power meter and saw that it was only drawing about 100mA. Was he really dead? But I decided I would…

Pros
  • Excellent design
Cons
  • Crumpled packaging
