DC 6-18V Lithium Battery Spot Welder 6 MOS Motherboard DIY Kit 90-200A

Features:

2 Designed a voltage stabilizing circuit, so that the MOS drive voltage no longer depends on the battery, and is more stable and reliable, so that the board supports 6-24V wide voltage use3 The new circuit layout greatly reduces the internal resistance, the heat is smaller, and the soldering is more laborious4 The external interface of LED and button has been added to facilitate the installation of the board in the box5 Optimized the program to make the operation more convenient and 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 荦)

Optional:

1.36-60AH car start battery2.20AH motorcycle battery 2 to 3 in parallel3.2S-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 modeTurn on the spot welder: long press the function button for 2 seconds to release the spot welder to turn onShift: 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 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 x circuit board (6 tubes)2 x soldering pens2 x input wires

1 x buzzer
