Portable DIY Mini Spot Welder Machine,Transistor Mini 18650 Lithium Battery Spot Welding Machine,for Capacitor, Spot Welding Tool Set with Soldering Pen,12V

The controller adopts single chip microcomputer control, accurate output pulse, LCD display screen, can display welding parameters.

The soldering pen and the input wire are connected by U‑shaped cold‑pressed terminals, which is convenient for disassembly and replacement.

Specification:

Item Type: Mini Spot Welder

Product Description:

1: This controller is mainly used for welding small battery repair power banks, power tools, model airplanes, etc.

2: This controller requires users to have a certain electronic basis and safety awareness.

3: Although sufficient protection has been done for the drive of the MOS tube, it is inevitable that the explosion tube will appear during use. If there is a explosion tube, just replace one.

4: For those with high welding requirements, please change the welding power source. After actual testing, when the battery uses 3S, 40C, 5000mHA, it can weld 0.1mm nickel-plated steel strip and 0.15mm nickel-plated steel strip perfectly. The welding needle needs to be ground into a round head, the pressing force is reduced, and it can also be welded; When the battery uses 12V, 50AH car level, it can weld 0.15mm nickel-plated steel strip perfectly. Note that it is a car battery, not an ordinary lead-acid battery.

Size: Approx. 0.1 ~ 0.15mm / 0 ~ 0.01in、

Package List:

1 x Spot Welder

Note:

Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
★★ 【WELDING POWER】Welding power can be powered by lithium battery or 12V car battery.The soldering pen and the input wire are connected by U‑shaped cold‑pressed terminals, which is convenient for disassembly and replacement.
★★ 【CONTROLLER】The controller adopts single chip microcomputer control, accurate output pulse, LCD display screen, can display welding parameters.The controller adopts automatic welding mode, while retaining the manual trigger interface, you can choose according to your own usage.
★★ 【POWER BOARD】The power board uses 2 ounces of copper, and the soldering pen wire and the input wire use 10AWG multi‑wire soft wire to increase the overcurrent capacity.
★★ 【IMPORTED SPECIAL CHIPS】Five 300A MOS tubes are driven by imported special chips, and the MOS tubes can be used as fast as 20nS, which can switch quickly to prevent tube explosion.
★★ 【FEATURE】The controller is mainly for welding 0.1mm to 0.15mm nickel‑plated steel strip, and the power input adds a 25V10000uF high‑frequency low‑resistance capacitor for energy compensation to increase stability.
