Agoal 6-Speed Portable Spot Welding Machine Mini Spot Welding Pen or Nickel Sheet for 18650 Battery Tool Adjustable Mini Spot Welding Pen for 18650 Battery Tool Kit

❥(^_-)Welcome

【feature】
Material: hard aluminum alloy
Gear position: 1-5
Dimensions: 110mm x 85mm x 30mm
Suitable for 0.1mm-0.15mm nickel plating

【description】
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, so that the nickel sheet is firmly welded. The welding machine itself has functions such as over-current protection, low-voltage protection, over-voltage protection and over-heat protection. Intelligent output current. It can be used safely, even if the soldering pen is short-circuited, it will not be damaged.
Principle: As shown in the figure, the microcontroller has a built-in high-speed protection system. 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 protect the welding machine.
Under normal circumstances, the function module will not trigger
After triggering the protection, lift the pen to automatically release the protection

【specification】
Product name: handheld desktop spot welder
Material: hard aluminum alloy
Gear position: 1-5
Weight: about 480g
Color: black shell, brass soldering pen
Dimensions: 110mm x 85mm x 30mm
Suitable for 0.1mm-0.15mm nickel plating
Nickel sheet size: about 3M

【feature:】
1. Automatic trigger, detachable soldering pen, TYPE-C charging, short circuit protection
Design: 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 protection
The working voltage platform of the power file battery is narrower than that of the ordinary K battery. The welding machine adopts a protection strategy of less than 3.2v, leaving space for low pressure and ensuring safety.
6. Low power consumption function
Long press to open/close, short press to switch 5 levels, all operations can be executed quickly and concisely. When it is off, it can stand by for up to one year due to its low power consumption function.
7. Thermal optimization
This product uses 2 ultra-high-rate model aircraft batteries, the discharge peak can reach 630A + all high-current wiring, and infrared thermal imaging is used to optimize the design to better
