Portable Mini Spot Welder Machine for 18650 Lithium Battery and Capacitor

Brand

Size

<li>Welcome to our shop! This Mini Spot Welder is designed to be powered by either a lithium battery or a 12V car battery. The controller features single chip microcomputer control, accurate output pulse, and an LCD display screen to show welding parameters. The soldering pen and input wire are connected using U-shaped cold-pressed terminals for easy disassembly and replacement. The controller has an automatic welding mode while also providing a manual trigger interface for your convenience. The power board uses 2 ounces of copper, and the soldering pen wire and input wire are made of 10AWG multi-wire soft wire to increase overcurrent capacity. With five 300A MOS tubes driven by imported special chips, these MOS tubes can switch quickly in as fast as 20nS to prevent tube explosions. The controller is primarily designed for welding 0.1mm to 0.15mm nickel-plated steel strips. To increase stability, a 25V10000uF high-frequency low-resistance capacitor is added for energy compensation in the power input. 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. Users are required to have a certain electronic basis and safety awareness when using this controller. 3. Although we have done sufficient protection for the MOS tube drive, tube explosions may still occur during use. In such cases, simply replace the affected tube. 4. For those with high welding requirements, please consider using a different welding power source. In our testing, when using a 3S, 40C, 5000mHA battery, this spot welder can perfectly weld 0.1mm and 0.15mm nickel-plated steel strips. The welding needle needs to be ground into a round head, reduce the pressing force, and it can still achieve successful welding. When using a 12V, 50AH car battery, it can perfectly weld 0.15mm nickel-plated steel strips. Please note that it should be a car battery, not an ordinary lead-acid battery. Size: Approx. 0.1 ~ 0.15mm / 0 ~ 0.01in Included: - 1 x Spot Welder - 1 x Connector - 2 x Power Input Line - 2 x Soldering Pen 100% Satisfaction: Our customers are our top priority. If you find any product problems after receiving the goods, such as damage and incorrect quantity of goods, please contact the seller immediately. We try our best to provide you with satisfactory after-sales service.<li>
