Tags: Self-made inverter strategy 2: Welding Yesterday, I already talked about the materials needed to make the inverter. Let's start making it now. Let us first take a look at the wiring diagram. First solder the terminals, then solder the 10K resistor, then solder the 12V regulator tube, then solder the 1N4007, then the 470 ohm 3W resistor, and finally prepare two 1200V 0.3μ induction cooker capacitors. Use the red pen of the universal meter to measure the white ring end of the 12V voltage regulator tube, and use the black pen to measure the no ring end. If the conduction or buzzer sound or the resistivity is very low (below 100), the voltage regulator tube is damaged and must be replaced, otherwise it will The phenomenon of field effect tube explosion occurs and the power supply is damaged. Use the red pen of a universal meter to measure the white ring end of the 1N4007 diode, and use the black pen to measure the non-ring end. The diode is damaged if it is turned on or the buzzer sounds or the resistivity is very low (below 100) and must be replaced, otherwise a field effect tube will appear. Tube explosion, and damage to the power supply. Then measure whether each circuit is connected to prevent false welding: false welding means that there is only a small amount of solder at the solder joints, resulting in poor contact, which is always on and off. False soldering and false soldering refer to that the surface of the weldment is not fully plated with tin, and the weldment is not fixed by tin. It is caused by the surface of the weldment is not cleaned, or the flux is used too little, and the welding time is too short.
