Reference description:
Features:
Brand new LCD display interface, more intuitive and clearer data display
Brand new MOSFET drive design, providing greater drive current and switching speed
Re-layout of components, more reasonable PCB design
Adopt 4MOSFET design to minimize the problem of MOSFET mismatch
Power supply selection
1: 12V car battery from 25 to 40ah, requires good performance and small internal resistance
2: 4000 to 6000mAh 45C to 60C 3S model airplane lithium battery
3:30 to 35ah 12V capacity lithium battery pack
Note: Can not use super capacitor as power supply
Welding nickel strip selection
The thickness of the welded nickel strip should be 0.1 to 0.12mm
Exceeding this thickness may cause the MOS tube to burn out
Energy setting
The energy must gradually increase from 01, and the maximum cannot exceed 30. It is recommended that the energy be below 30.
Exceeding the above conditions may damage the controller!
Switch machine
In the shutdown state, long press the square button, the buzzer will beep three times, and the controller will turn on
In the power-on state, long press the square button, the buzzer will beep twice, and the controller will shut down
parameter settings
There is only one parameter that needs to be set to control the welding energy. The larger the parameter setting, the higher the welding energy.
In the power-on state, use the up and down triangle buttons to set the welding energy parameters
Mode selection
There are three working modes for control STOP MANUL AUTO
STOP: In this state, the controller cannot be welded
MANUL: manual welding mode, welding through an external trigger switch
AUTO: automatic welding, when the soldering pen touches the nickel strip, the delay is 1 second, and the welding is automatically completed
Welding operation
Select the automatic mode, set the energy to 1 first, and then put the nickel belt on the test machine (don’t weld the battery yet)
If the welding is not possible, gradually increase the energy until it can be welded, do not increase the energy
Before completing the welding, make sure that the soldering pen is firmly crimped onto the nickel strip, otherwise it will blow through.
common problem:
1: Cannot be welded
the reason:
Generally, the battery capacity is too small and the ability to release current is insufficient
Nickel belt is too thick
Solution:
Choose a battery that meets the requirements
Welding nickel tape between 0.1mm and 0.12mm
2: Welding explosion fire, nickel belt perforation
the reason:
Too much energy
The soldering pen is not firmly pressed
There are flammable materials under the nickel belt
Solution:
Energy down
During the welding process, keep the welding needle completely firmly crimped on the nickel strip
During the welding process, no flammable materials must be placed under the nickel belt
3. MOS tube burned out during welding
the reason:
Battery capacity is too large
Nickel belt is too thick
Solution:
Choose a battery that meets the requirements
Welding nickel tape between 0.1mm and 0.12mm
