Description

Portable 12V Battery Storage Spot Welding Machine DIY PCB Circuit Board Pen Tool
Features
:
Version 1
Can be welding 18650/26650/32650 lipo battery, it is portable, stable and reliable
System voltage: 12V
Working current: 90-150A
Suggested battery:
20-45ah Lead-acid battery with good performance and small internal resistance
3.5-5.5ah 45C 3S aeromodel lithium battery pack
30-35ah capacity 18650 battery pack
This circuit with a 12V battery will become an energy storage spot welding machine for welding nickel pieces such as lithium batteries and nickel-chromium batteries. According to different configurations, the thickness can be about 0.1MM-0.15mm
Notice：The 18650 battery and DC power cannot be used as a power supply. It must have a high rate RC battery or a car battery!
Please start from the lowest gear when you use it, do not start from the highest gear, easy to burn off.
Version 2:
Can be welding 18650/26650/32650 lipo battery, it is portable, stable and reliable
System voltage: 11.5V-14.8V
Working current: 100-200A
Suggested battery:
36-45ah Lead-acid battery with good performance and small internal resistance(The internal resistance is less than 10 milliohms, and the discharge current is greater than 100A), such as a new car starting battery!)
4000mah 35C-8000mah 30C 3S model airplane lithium battery
30-35ah capacity 18650 battery pack
Instructions for use:
Function buttons: 1, used to switch the machine, 2 used to switch gears!
When the power is turned on, the default is the first gear. Press the button for 2 seconds to release
The gear is increased by one gear, and the buzzer sounds and the LED flashes corresponding to the number of gears.
For example: the 3rd gear, the buzzer sounds three times, the LED flashes 3 times, a total of 5 gears. The spot welding intensity is gradually strengthened from the 1st gear to the 5th gear
5 is the strongest!
After the 5th gear, press and hold the button again. It will power off. In the off state, press and hold the button to power on, and the gear will return to the first gear
