6 MOS 5 MOS 18650 Lithium Battery Spot Welding Machine Motherboard DC 6-18V 12V

6 MOS 5 MOS 18650 Lithium Battery Spot Welding Machine Motherboard DC 6-18V 12V DC 6-18V Spot Welder 6MOS Welding Machine Circuit Board Kit 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 4 screws 3 sets 5 buzzer 1 6 nickel sheet 1 meter DC 12V 5 MOS 18650 Battery Energy Storage Spot Welder Machine Item Detail: The circuit board of this spot welder can be used to weld 18650/26650/32650 lithium batteries. Advantages: convenient Carry, stable, reliable and durable. Low cost, own car start battery, or high-power battery pack, connect it Ready to use! Save production cost! Users need to bring their own 12V battery for power supply, and the welding current is about 90A~130A. For common 0.1mm~0.12mm nickel plated sheet welding is easy. Please make sure your battery can have more than 90A Current, otherwise it will not be possible to weld! Power supply voltage: 12V-15V Working current: 90-150A (discharge below 90A, it will not work.) A battery with a large discharge current will directly affect the welding effect. The following batteries are recommended: 20-45ah lead-acid battery with good performance and small internal resistance (internal resistance is less than 10 milliohms, and the discharge current is greater than 90A), such as starting the battery in a new car! 3.5-5.5ah45C 3S model airplane lithium battery pack 30-35ah capacity 18650 battery pack Power requirements: Spot welding is welded by the principle of rapid local heating and cooling by high current, Need sufficient current supply, generally used 0.1-0.15 nickel plated sheet welding current About 90-150A, so the working power of the circuit board must be greater than or equal to 150A. The following battery packs can be used as working power 12V car starter power, 3S high-rate battery pack for model airplane, three-string high-rate lithium battery pack, Hitachi 409003 string battery pack, lead-acid battery with good performance above 12V20A. Calculation formula: capacity X discharge rate = load capacity Take 4000ma aeromodelling battery as an example, the discharge rate is 45C (4AX45C=180A) 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 and release it. 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 beeps three times, the LED flashes 3 times, a total of 5 gears. Spot welding strength from gear 1 to gear 5 Degree gradually strengthened The 5th gear 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 at the same time.
