Handheld DIY Spot Welders for 18650 Battery Spot Welding Machine Tool Kits, 501 Original

Handheld Portable DIY Spot Welders for 18650 Battery Mini Spot Welding Machine Automatic Trigger Tool Kits with Quick Release Pen Nickel Plate Feature:1. Automatic trigger, detachable soldering pen, TYPE-C charging, short circuit protectionDesign: Sturdy appearance, anti-light splash, firm connection, scattered soldering pen, service life of 50,000 cycles.2. 0.1 smm nickel bar welding force, steel shell 18650 battery assembly. For large monomers, the aluminum electrode must be welded after it becomes nickel, and the welding point is about 800 points.3. Support welding when charging, theoretically the battery life is unlimited, and the battery capacity is about 5AH.4. Lithium battery protection.The first generation of this product uses a 50% discharge method to protect the Keng battery. The existing second-generation products use 4.2V instead of 4.25V charging method. While preventing full charge, it avoids the trouble of charging and waiting for each use.5. Low voltage protectionThe working voltage platform of the power file battery is narrower than that of the ordinary K battery. The welding machine adopts a protection strategy lower than 3.2v, leaving space for low pressure and ensuring safety.6. Low power consumption functionLong press to open/close, short press to switch 5 levels, all operations can be executed quickly and concisely. When in the off state, it can stand by for up to one year due to the low power consumption function.7. Thermal optimizationThis product uses 2 ultra-high-rate model aircraft batteries, the discharge max can reach 630A + all high-current wiring, and infrared thermal imaging is used to optimize the design to better distribute the discharge current.8. Unique secretsShort circuit protection of soldering penDescription:The welding machine precisely controls the output current of the MOS tube through the single-chip microcomputer. A high temperature of more than 2000 degrees will be generated at the welding point, so that the nickel sheet is firmly welded. The welding machine itself has the functions of over-current protection, low-voltage protection, over-voltage protection and over-heat protection. Intelligent output current. Even if the soldering pen is short-circuited, it can be used safely without damage.Principle: A high-speed protection system is built into the microcontroller. When the welding current is too large, the ultra-high-speed comparator will immediately turn off the output, as shown by the red arrow, in order to achieve the purpose of protecting the welding machine.Under normal circumstances, the function module will not trigger.After the protection is triggered, lift the pen to automatically release the protection.Specification:Item: handheld desktop spot welderBattery capacity: 5000mahSuitable for 0.1mm-0.15mm nickel platingMaterial: hard aluminum alloySize: 103x83x28mm Note:Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
