12V Portable Mini Spot Welder 18650 Lithium Battery Spot Welding Machine Full Set Full-Featured Version

Features:

- Smart CNC spot welding machine
- 99 gears for precise adjustment of welding intensity
- High-speed microcontroller intelligent program
- Real-time display of battery voltage and spot welding strength
- The peak current of 8 MOSFET imported from Germany can reach 1600A (single load current 200A maximum). Limit temperature 175℃; 40V breakdown voltage; 0.8mΩ minimum on-resistance. Support 100-200A welding
- LED displays in 3 digits. Welding intensity, voltage and alarm at a glance
- Used as a spot welding machine as well as a voltage meter. With built-in 12-bit high-precision ADC, the voltage measurement accuracy can reach 0.01V. Voltage testable range: 8-24V. After connecting to power supply, it will automatically display the voltage of the power source
- Suitable for 0.1-0.15mm nickel sheets, enabling clean solder joints

Package Included:
1. Motherboard x 1
2. Spot welding pens x 2
3. Input cables x 2
4. Shrinkable tubes x 2
5. Copper lugs x 2
6. M5 screws x 4
7. Flange nuts x 4
8. Digital tube 1
9. Capacitor x 1
10. Buzzer x 1
11. XT60 socket x 1
12. Foot switch socket x 1

Note:
- It can be powered by model airplane battery which is not included in the package.
- Batteries and other items pictured are not included, for demonstration purposes only. Thank you for your understanding!



1. Output -: connects black welding pen
2. Digital display (3-digit): display the voltage of power supply or the welding intensity. The gear and voltage are displayed alternately every second
3. Buzzer: It will make a sound when spot welding, pressing a button, or when an abnormal alarm is issued
4. Power supply +. Requiring 10-16.8V 100-200A
5. Foot switch: connect a switch to manually control spot welding
6. Output +: connect red welding pen
7. Shift down/enter setting: 7.1. In the main interface, short press the button once, the welding strength can be reduced by one level. 7.2. In the main interface, long press the button to enter the setting menu, and then long press the button to exit the setting
8. Shift up; turn on/off: 8.1. In the main interface, short press the button once and the welding strength can be increased by one level. 8.2. Press and hold the button to turn off when powering on; press and hold the button to turn on when powering off
9. Power supply -
10. XT60 socket for model airplane battery: It is recommended to use a battery above 3S4000MAH35C, that is, the discharge requirement is more than 100A, preferably 150A, but it is not recommended to exceed 200A


When in standby, the digital tube will alternately display the gear and the power supply voltage every second. When it displays in d+**, it means the current gears is **. For example, d99 means the welding intensity is the 99th gear. When it displays in 12.2, for example, it means the voltage of power supply is 12.2V. And if the voltage is 9V, and 9.00 will be displayed.
