        DIY Portable Mini Spot Welder Set

        DIY Portable 12V Battery Energy Storage Spot Welding Machine P.C.B Circuit Board Welding Equipment Spot Mini Welder Set Pen For 18650 26650 32650 Battery Welding Machine Battery Welding Tools Set

        The circuit board of this spot welder can be used for welding 18650/26650/32650 lithium batteries. Advantages: portable, stable, reliable and durable. Low cost, you have a car starter battery, or a high-power battery pack, you can connect it and use it! Save production costs!

        Used for welding 18650/26650/32650 lithium-ion batteries, advantages: portable, stable and reliable, durable.

        Users need to bring your own 12 v battery power supply, welding current is 90 a ~ 130 a, for common 0.1 mm ~ 0.12 mm nickel plated piece of welding. After several generations of product updates, now it is upgraded to automatic trigger welding, liberation button on the finger.

        Specification:
        Can be welding 18650/26650/32650 lipo battery, it is portable, stable and reliable
        System voltage: 12V-14.6V
        Working current: 90-150A

        Suggested battery:
        20-45ah Lead-acid battery with good performance and small internal resistance
        3.5-5.5ah 45C 3S are model 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

        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
        Tips:
        The package include should be spare parts, which need welding and assembly by yourself
        And it also need you to have some welding technology and circuit knowledge.
        Please mounting the capacitor to avoid the board burn and other issue before use. (ps: The 12V spot welder’ capacitor has been welded to the board in advance.)

        Note:
        If the battery is pretty good and the internal resistance is very low, and then there may be large current overload.
        If you are not sure about your battery, it’s better to extend the wire by around 1 meter with 2.5² or 4² wire, then it will reduce the risk of power tube burnt.

        Package Include:
        1pcs x Main Circuit Board
        1pcs x Buzzer
        2pcs x Input Wire
        2pcs x Output Line with Welder Pen
