This is an infrared soldering iron. To build it, we need the following materials and tools.
Materials: car cigarette lighter, network wire with a cross section of 1.5 mm2 – 1 meter, a wooden handle from a burnt-out soldering iron, terminals with an inner diameter of 3 mm -2 pcs, two male plugs for connecting to the output connector of the power supply, bolts and nuts M 3, cambric.
Tools: soldering iron, tweezers, solder, wire cutters, pliers, power supply for 12V * 5-10A, drill and drills.

Step -2 . In the center of this ring, using a nut and an M3 bolt, we attach a terminal in which the power wire will be crimped and soldered. The center of the spiral is attached to the ceramic washer with a small pin.
The positive power cable must be connected to it. We bite off the center of the round terminal with pliers and with pliers we squeeze it under our pin.
Step -3 … We drill a metal tube, which was fixed on a ceramic washer, into a lower hole in it up to 6 mm. We insert this tube up the wooden handle of the soldering iron, it fits there very tightly. We pass the network wire through the handle. We crimp the upper ends of the wire in our terminals.
