Description of 🔋 Mini Spot Welder Set with Safe LCD Display for Transistor 18650 Battery and DIY Lithium 18650 Batteries - Power Tools Mini Spot Welder Machine (6pcs)

【Mos Drive Design】 Adds a transient diode to protect MOS from tube explosion.The welding pen line and the input line are made of 10AWG multi-wire flexible wire to increase the overcurrent capacity. The controller is mainly for 0.1mm to 0.15mm nickel plated steel strip welding.A 25V10000uF high frequency low resistance capacitor is added to power input for energy compensation to improve welding stability. 【Wide Selection of Welding Power Supply】Lithium battery power supply or 12V car battery. The controller is controlled by single chip microcomputer, and the output pulse is accurate to ensure the welding quality. 【Stable】A 25V10000uF high frequency low resistance capacitor is added to power input for energy compensation to improve welding stability. 【Design】The controller adopts automatic welding mode, while retaining the manual trigger interface, which can be selected according to their own use. 【With LCD Display Screen】The controller has LCD display screen, which can display welding parameters. U-shaped cold pressing terminal is used to connect the welding pen and the input line for easy removal and replacement.

Not decided. on this product.

I was pleased with the assembly of this machine. But unfortunately the one I received had an internal malfunction and didn't work. I sent it back and bought another one.

Pros
  • Spot Welder
Cons
  • Low Repairability

If you get a good one, it works for a while.

I had 4 of these. 1st is dead on arrival. The 2nd worked for 5 months, changed mosfets several times. 3. direct short circuit via mosfets, risk of fire and electric shock. 4. worked 3 times and then shorted the mosfets. 2 SLA 12V batteries used in parallel to provide plenty of power, never mind. Thanks to Revain I got everything back except the 2nd.

Pros
  • Welding machines and accessories
Cons
  • Not all will fit

Works great... after you fix it. Buyer warning!

The cheapest. One reason is that a component is missing. And the design is missing a very important part to keep it from blowing through. If you rely on your soldering skills and are willing to do a little research (YouTube) you can make this thing work great. It must be repaired before it is used for the first time. So if you don't want that, BUY SOMETHING ELSE! It will break very quickly if you don't change it. I fixed mine by adding a 1000uF capacitor to the circuit and it worked great on…

Pros
  • Welders
Cons
  • Frequency
