DIY Pulse Soldering Iron

This video shows the manufacturing process of a very simple pulse soldering iron. More precisely, the soldering iron is pulsed only in terms of rapid heating. At this soldering iron, the tip itself is the heating element. After the soldering iron is heated it can be used like any other soldering iron, designed for long-term operation.

In this soldering iron, it is very easy to change the tip, and it does not require a separate ground wire, since the soldering iron power circuit is connected to the tip. That is, you can ground any of the power wires. In all my homemade soldering irons, I minimized the distance from the grip to the end of the tip.

To build a soldering iron does not require micanite or mica, which greatly simplifies the search for materials.
I welded copper lugs to a nichrome wire using a makeshift gas burner:    • Миниатюрная газовая горелка   Усовершенств...  

Any adjustable power supply with an output current of 10 Amps is suitable for powering the soldering iron. Amateur enthusiasts usually have such a block. But if there is no such power supply, then it is easy to make it yourself from the power supply from a compact fluorescent lamp and a DC-DC regulator: https://oldoctober.com/ru/smps/
