Product Description
Needs to be used while charging
UF20B Built-in Farad Capacitor
Supports global voltage, input voltage is 100-240V.
Built-in adapter makes the spot welder look neater.
UF20B can't store power, you need to charge it while using it.
When you find unplugging the power supply, it can still be turned on because there is only a little bit of power inside, after that it will slowly consume by itself.
If you are a beginner, please read our instruction manual, use our matching nickel sheet to practice more, find the force of hand pressure, familiar with the welding machine.

0.4mm nickel plated sheet
0.4mm steel sheet
0.4mm iron sheet
0.1mm pure nickel sheet(Flux required)
0.1mm copper sheet (Flux required)
Materials such as these can be spot welded, and even thicker materials may be welded.
For building battery packs, this spot welding machine is professional.
Spot Welder Lead Pens
The new intelligent hand-controlled pen is controlled at will and triggered precisely.
On the basis of automatic spot welding, the intelligent hand-control welding pen is created again, which can control the trigger time at any time and spot weld meticulously and more accurately, and it can really be controlled at will and triggered accurately.

Foot Pedal Mode
The spot welder is set up to attach a foot pedal. This frees up both of your hands to pinpoint your position and then step on the pedal on the floor, making it easy to get your job done.
Button Marker
We've labeled the buttons next to each one so that you can be very clear about what the button means without an instruction manual or other documentation.
Aluminum Alloy Material
The spot welder has a rounded curved appearance so that our body parts won't get cut when we touch them. The shell is made of aluminum alloy, which is very tough and strong, very safe.

One of my cell orders was short one cell
One of my cell orders was short one cell. When I went to send a text to the customer contact (this is rare and awesome way to reach out), the reply on a national holiday came within 15 min. That level of customer service is incredible, like family. I really appreciate that!

Wow, these cells are great!
I purchased some of these tabless cells to try on my 1S 3" HD Toothpick drone build, and, albeit a bit heavy for 1S, it flies pretty well. Not a freestyle monster, but an endurance beast with decent send. These cells shrug off the demands of a BETAFPV Matrix HD AIO flight controller/12A ESC and some 1202.5 11000KV motors. I'm getting 15+ minutes of speedy flight time from a single cell trying not to go below 3.2V, and about 20+ minutes cruising. Love these cells and will definitely buy more when time comes, only from DIY500AMP, who are terrific!
