                    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 is generated at the welding point to make the nickel sheet welded firmly. The welding machine itself has functions such as over-current protection, low-voltage protection, over-voltage protection, and over-temperature protection. Intelligent output current. It can be used safely, even if the soldering pen's short-circuited, it will not be damaged.

                    Principle: As shown in the figure, a high-speed protection system is built in the microcontroller. When the welding current is too large, the ultra-high-speed comparator will instantly turn off the output as shown by the red arrow to achieve the purpose of protecting the welding machine.
                    Under normal circumstances, this function module will not trigger
                    Once the protection is triggered, lift the pen to automatically release the protection


                    Product Name: Handheld Desktop Spot Welder
                    Material: hard aluminum alloy
                    Weight: about 480g
                    Color: black shell, brass soldering pen
                    Size: 110mm x 85mm x 30mm
                    Suitable for 0.1mm-0.15mm nickel plating


                    1. automatic trigger, detachable soldering pen, TYPE-C charging, short circuit protection
                    Design: Sturdy appearance, light splash resistance, firm connection, dispersion brazing pen, life span of 50,000 cycles.

                    2. 0.1 smm nickel strip welding force, steel shell 18650 battery assembly. For large monomers, the aluminum electrode must be welded after turning to nickel, and welding is about 800 points. 

                    3. Support welding while charging, theoretically unlimited battery life , 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 a charging method of 4.2V instead of 4.25V. While preventing full charge, it avoids the trouble of recharging and waiting for each use.

                    5. Low voltage protection
                    The working voltage platform of the power file battery is narrower than that of ordinary Keng battery. This welder adopts the strategy of less than 3.2v protection, leaving space for low pressure and guaranteeing safety.

                    6. Low power consumption function
                    Long press to turn on/off, short press to cycle through 5 gears, all operations can be performed quickly and concisely. When in the off state, thanks to the low power consumption feature, it can be standby for up to one year.

                    7. Thermal optimization
                    This product uses 2 ultra-high-rate model airplane batteries, the discharge peak can reach 630A + all high-current wiring, and the infrared thermal imaging is used to optimize the design to better share the discharge current.

                    8. Unique secret
                    short-circuit protection of the soldering pen
