    1.5M Foot Switch for This Spot Welding Machine: ID 1747573

    This kind of controller has a very large instantaneous welding current, 100 to 200A, and the heat inside the mos tube is also very large! Therefore, when testing the machine, the welding energy should start from the minimum, and the welding can be guaranteed. Don"t set too large! The most important thing is to pay attention to the range of the power supply and the thickness of the welded nickel strip! If the nickel band is too thick, the tube will burn easily!

    Notice:
    Please read the instructions in the package carefully,We donot provide extra technical support for it.
    Please make sure you know how to config it before purchasing.

    Features:

    1. Wide selection of welding power supply: lithium battery power supply or 12V car battery.
    2. The controller is controlled by a single chip microcomputer, and the output pulse is accurate to ensure the welding quality.
    3. With LCD display screen, can display welding parameters.
    4. The welding pen and the input line are connected by U-shaped cold-pressed terminals, which is convenient for disassembly and replacement.
    5. Using automatic touch welding mode, while retaining the manual trigger interface, you can choose according to your own use.
    6. The board uses 2 Gusi copper to increase the overcurrent capacity.
    7. Using 5*300A MOS tubes, non-disassembled MOS tubes.
    8. The MOS tube driver adopts the imported special chip driver. The fastest MOS tube can be hit with 20nS. The switch is fast to prevent the explosion of the tube and the non-triode push-pull drive.
    9. The MOS drive design adds a transient diode to protect the MOS and prevent the explosion of the tube.
    10. 10AWG multi-filament flexible wire is used for the welding pen line and the input line to increase the overcurrent capacity.
    11.The controller is mainly for welding nickel-plated steel strips from 0.1mm to 0.15mm.
    12. A 25V10000uF high-frequency low-resistance capacitor is added to the power input for energy compensation, which increases welding stability.

    Instructions for Use:

    1: Power Connection

    The controller comes with a 20cm long 10AWG input wire. One end has been crimped with a U-shaped terminal, and the other end has not been processed. Connect the crimped U-shaped terminal to the control power input terminal, and the other end is processed according to its own power supply. Do not connect the negative electrode wrong.

    2: Switch on and off

    There is a power switch under the control board. After pressing, wait for 3 seconds. After the buzzer drops, the LCD lights up and the boot is complete. Press the power switch again to shut down.

    3: Screen description and parameter adjustment.

    WELD ENERGY: 01-99 (adjustable by up and down keys)
    INPUT: Display input power voltage
    WELD WAY: Manual / Auto (Adjust via the "square label" button.)

    4: Welding

    Keep the welding pin clean. If the welding pin is polished into a round head, the welding effect can be improved. There are manual and automatic methods.

    Specification:

    Material: Metal
    Input line length: app.20cm/7.87in
    Length of welding pen: app.30cm/11.81in

      TLDR: Hold welding electrodes at 45degree angle for strong welds and for 0.15mm nickle 35-40 welding energy

      Received it In a normal time frame, in like a month, not too bad. In the package there is the unit itself and all the components you need for it to work. They include a little barrel jack that you can use to connect a pedal switch, but you don't have to have it. They Also include some extra mosfet, in the case of you burning them out. They might come in handy down the road.
      The welder works off of a 12v power source. I used a 12 v car battery with 460A of power, but you could probably go with anything that can do above 180-200A.one thing that is kind of annoying is that the included leads for connecting to the battery are short, buuut you can't really complain for 18 eur and also they would be perfect if u used a lipo.
      For my first welds I used 0.15 pure nickle strip but no matter how high I set the welding energy it didn't want to stick to the battery. BUT after a little bit of trial and error I figured out that you have to hold the welding electrodes at an about 45degree angle and not straight up. After that discovery pretty much all the welds held strong. I have used it to make this little battery on the picture and for it 35-40 welding energy works the best.
      OH and I use the auto mode on the welder, witch means if I connect the electrodes to the nickel, some beeps sound and it welds. Haven't tried the pedal but in my opinion this way works pretty well.

        Q: what is this device used for?
        A:
        For spot welding nickel plated steel strips to batteries to make battery packs. As the spot weld is almost instant it does not overheat the battery which is very important, especially with lithium batteries.

        Q: BangGood: Please clearly indicate in your product description whether any other components are required to get started other than the battery. We need better description of the battery requirements. Are you meaning we must use a 12v automobile battery? What kind/voltage of Lithium Ion battery will work? Thanks. JE
        A:
        Lithium battery y or 12V car battery, or Super capacitor is OK ,other components aren't required to get started, which is very convenient.I very like it.

        Q: Can this be powered by a 12 volt Bench power Supply? If Yes, what amperage would be required ?
        A:
        Definitely not, for this you need at least ***** batteries in parallel, each of which can deliver 20A, so you have 100A available, even more is desirable._That's why people often make a spot welder from a transformer from a microwave oven (I have one) - it works much better than these solutions (you can weld quite thick strips), but it's not portable, the device is bulky and heavy - that's why I want to buy something like this - for repairs outside my apartment.

        the transistors may have been damaged, or the gate control is damaged, causing the transistors to remain on. they should only be pulsed briefly when working.

        Q: what is the weld switch plug used for in the operation.?? What do you connect it to???
        A:
        That switch is not (as mentioned) the power switch, the welding switch is a manual trigger for welding. A plug is supplied but you need to attatch a switch yourself. You can buy these for pennies here or at other sites. They are meant to be pressed with your foot so your hands are free to manage the weldig pens. Press foot switch once, spotwelder beeps (as a warning to announce it's going to do the business) and then welds it.

        Q: Good evening friend wanted to know why the product that was purchased by me has no tracking number?
        A:
        I don't know how shipping tracking works. I bought a cheap (17 usd) vacuum cleaner and got full tracking despite hearing before the same that Jorgehpm said (25 USD threshold). Regardless, this is was a question for customer support, not the items question section. While this may no longer help you, hope it helps future buyers.

        Q: Spot Welder protection is it possible to protect the module against short-circuit with a fuse and if so, what value should the fuse have?
        A:
        It is very hard to protect this unit with a fuse as the peak currents are very high and the fuse would not blow before the unit failed.

        A:
        1. Check all soda and appliance connections. 2. Use a car battery. 3. Make the right modifications to your model. To do this, as you can put links, search the web: All Mini Spot Welder versions: circuit analysis, circuit analysis and circuit analysis You will find the videos of Luca that explain it in detail.
