The spot welder works like a charm. Before using, make sure to solder the capacitor to the input of the device. I spot welded a 1.5 mm thick nickel strip with the LVL 3 power (Blue colour). For the best result use a big 4s lipo Battery. I used a 5000 mAh 60C lipo. You need at lease 150A discharge current for the device to work properly (You can calculate the max discharge current by multiplying the capacity with the C rating. For example, if the Lipo has 2000mAh and 100C the calculation should look like this: 2000mAh * 100C = 200A). The cables of the spot welder get a bit warm after a few spot welds on LVL 3 power output. The device should be able to spot weld more than 2.5 mm thick nickel strip with eas. How to use: - Connect the Battery (Obviously) - Press on the button to select your Mode/LVL (I used LVL 3 for a 1.5mm thick nickel strip. Test your welds on two nickel strips) - Press the two pins firmly on the nickel strip. NO GAP should be between the two things you want to spot weld. - When the led flashes up, the spot weld should be done. Congrats you made your first spot weld ;)

jonas.huetter@MarkGood Thecapacitor is only there to smooth out the voltage of the battery under the short impulse so the device doesn't shut down or get damaged. People who use Capacitors have a much higher Farad rating (Farad is described how much energy can be stored in the capacitor). You won't need to add a second capacitor, mine is still fine after more than 1000 spot welds.
