Homemade method of electric soldering iron:
Remove the inductance and capacitance of the red circle in the circuit
The red color is the modified part. The production process is described below.
1. Use a paper clip to make the welding head.
2. Find a suitable high-frequency transformer, which can bypass the primary 100åŒ, with a wire diameter of about 0.2mm; the secondary one, with a diameter of about 1mm, multiple parallel copper wires are for temporary testing, and there will be actual Production process.
3. After testing, it is in line with the expected results.
4. Find a micro switch, make a handle, and find some copper wire with a diameter of about 1mm.
5. Install the switch and circuit in the handle. Wind the secondary of the high frequency transformer.
6. Connect the high frequency transformer secondary to the tip.
7. Finished.
