<p>Portable DIY Mini Spot Welder Machine,Transistor Mini 18650 Lithium Battery Spot Welding Machine,for Capacitor, Spot Welding Tool Set with Soldering Pen,12V</p> <p>The controller adopts single chip microcomputer control, accurate output pulse, LCD display screen, can display welding parameters.</p> <p>The soldering pen and the input wire are connected by U‑shaped cold‑pressed terminals, which is convenient for disassembly and replacement.</p> <p> Specification: </p> <p> </p> <p> Item Type: Mini Spot Welder </p> <p> </p> <p> Product Description: </p> <p> 1: This controller is mainly used for welding small battery repair power banks, power tools, model airplanes, etc.</p> <p> 2: This controller requires users to have a certain electronic basis and safety awareness. </p> <p> </p> <p> 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.</p> <p> 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. </p> <p> </p> <p> Size: Approx. 0.1 ~ 0.15mm / 0 ~ 0.01in、</p> <p> </p> <p> Package List: </p> <p> </p> <p> 1 x Spot Welder </p> <p> </p> <p> 1 x Connector </p> <p> </p> <p> 2 x Power Input Line </p> <p> </p> <p> 2 x Soldering Pen</p> <p> </p> <p> Note: </p> <p> </p> <p> 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. </p>
