    kWeld - "Next level" DIY battery spot welder

    What's the use of deliberately killing the components? :shock: Burned eyes - at least are your eyes ok now?

    The welding electrodes don't seem to be shorted - could it be the pedal?

    kWeld - "Next level" DIY battery spot welder

    Didn't think about it. :( I ordered XT90 connectors along with the hobbyking battery recommended at kWeld page. Should have probably ordered XT150 connectors instead to replace the battery connector...

    kWeld - "Next level" DIY battery spot welder

    kWeld Spot Welder Questions 2018.09.27
