For any radio amateur, a soldering iron is one of the main tools. This device is intended mainly for soldering radio components and tinning the surfaces of printed circuit board conductors. Soldering irons differ in the way of heating, modern soldering irons are mainly heated by electric current, but there have been, and still exist, such soldering irons that must be heated with an open flame. The design of an electric soldering iron is not very complicated and you can assemble it yourself.
Necessary
Wood block, resistor, copper bar, metal strip, power cord, plug
Instructions
Step 1
Take a piece of wood and cut a handle out of it for the future soldering iron. Then, in the center of the handle, drill a through hole, the network wire will be passed through this hole.
Step 2
Next, take a 2 kOhm resistor of the "PEV" brand and select a copper rod under its central hole. Grind the end of this bar to match the shape of the soldering iron tip, and then place the bar inside the resistor, it should sit firmly in it.
Step 3
Then, take a metal strip and make a clamp for the resistor out of it. Wrap the resistor with this strip, drill holes in it and use a bolt to clamp the resistor in it.
Step 4
After that, unbend the extreme ends of the clamp and drill one hole in them. Through these holes, using screws, attach the clamp with the resistor to the end of the wooden handle, but for convenience, first pass the power cord through the hole in the handle.
Step 5
Next, connect the ends of the cord to the terminals of the resistor and carefully insulate the bare conductive places. Connect the plug to the other end of the wire, the soldering iron is ready.
