Product Details
Features:
1. The board uses 6 MOS tubes with extremely low internal resistance, a single 300A, which greatly improves the stability of the circuit
2. Designed a voltage regulator circuit, so that the MOS drive voltage is no longer dependent on the battery, and is more stable and reliable, so that the board can support 6-24V wide voltage use
3. The new circuit layout greatly reduces the internal resistance, generates less heat, and makes soldering more labor-intensive
4. Added external interfaces for LEDs and buttons to facilitate the installation of the board in the box
5. Optimize the program to make the operation more convenient and more free
Requirements:
Working voltage: 6-24V (recommended to use within 6-18V, because the voltage is too high, the spark will be very large, and it is difficult to weld)
Working current: 90-200A (the best working current is about 150A, if the current is too small, it will not be able to weld )
Optional:
1.36-60AH car start battery
2.20AH motorcycle battery 2 to 3 in parallel
3.2S-5S 4000mah Lithium-ion battery with discharge above 30C
Instructions for use:
Function buttons: 1. Used to switch the machine 2. Used to switch gears and spot welding mode
Turn on the spot welder: long press the function button for 2 seconds to release the spot welder to turn on
Shift: the first gear is the default after power on, long press the function button for 2 seconds to release it to increase by one gear. There are 5 levels in total, and there will be sounds and LED lights! For example: at level 3, the buzzer sounds three times and the LED flashes three times. There are 5 levels in total, from level 1 to level 5, the spot welding strength is gradually strengthened, and level 5 is the strongest! After level 5, press and hold the button again, it will power off, and press and hold the button in the off state to power on, and the gear will return to First gear.
Switching mode: In any gear, short press the function key, there are 2 modes of switching mode: timing output mode and trigger mode
Package Included:
1 circuit board (6 tubes) 1 piece
2 soldering pens 2
3 input wires 2
