Intelligent CNC spot welding machine, 99-speed precise gear adjustment, high-speed single-chip intelligent program, real-time display of battery voltage, spot welding strength can be seen
8 MOS tubes imported from Germany, the peak current can reach 1600A, the welding is more transparent, and the solder joints are more beautiful
3-digit LED digital display, gear voltage alarm, clear at a glance, both a spot welder and a voltmeter
1600A high current load capacity, support 100-200A high current welding, and the thickness of spot welding is further improved
Built-in 12-bit high-precision ADC, voltage measurement accuracy can reach 0.01, voltage testable range: 8-24V, automatically display voltage when connected to power

Specification
1. Output negative: connect with black soldering pen
2. Digital tube (3 digits): used to display the voltage of the power supply or the current gear, the gear and the voltage are displayed alternately, switching once per second
3. Buzzer: It will sound when spot welding, key connection, or abnormal alarm
4. Power positive: power positive input, requirements: voltage: 10-16.8V, current: 100-200A
5. Foot switch interface: connect a switch to manually control the trigger of spot welding
6. Output positive: connect with red soldering pen
7. Button 1: There are 2 functions: 1. Downshift, in the main interface, short press it, down one gear
2. Enter or exit settings: long press on the main interface to enter the settings menu, then long press again to exit the settings
8. Button 2: There are 2 functions: 1. Add file: in the main interface, press briefly to add one file
2. Power on and off: long press to power off when power on, long press to power on when power off
9. Negative voltage: connect to the negative pole of the power supply
10. XT60 interface: model aircraft battery can be used as power supply, model aircraft battery requirements: battery above 3S4000MAH35C, that is, the discharge requirement is more than 100A, preferably 150A, but not more than 200A

When in standby, the digital tube will alternately display the gear position and the power supply voltage, which will be exchanged every second.
When the display is: d + two digits are the gear display. For example: d99, which means: 99 gears
When the three digits such as 12.2 are displayed, it means that the voltage of the power supply is: 12.2V
If the voltage is lower than 10V, it will display 2 decimal places of precision, if it is higher than 10V, it will display 1 digit precision

Compared with the automatic trigger version, the full-featured version has more:
1. There is a foot switch interface, you can connect an external button, click and click! Of course, you can also leave the external switch unconnected, and place the two pens on the nickel sheet and hold it down. After 2 seconds, it outputs
2. There is an XT60 interface, which can be used as a power supply with a model aircraft battery. It can be used directly by connecting to the interface, which is very convenient.
