Electric soldering iron for electronic work. In 1946, Carl E. Weller applied for a patent for his soldering gun that could heat instantaneously and began production of the "Speedy Iron" in Pennsylvania. [12] It was manufactured through the Weller Manufacturing Company, and this product was the first instantaneous thermal soldering gun.
The main technical parameter of the contact soldering station is the power. The power determines the operation convenience and soldering effectiveness. The modern stations have power from 10 to 200 W and more. The most common are the models with 50-80 W power. The higher is the power the more amount of heat you may transmit for the same time.
Resistance soldering is soldering in which the heat required to melt the solder is created by passing an electric current through the parts to be soldered. When electric current is conducted through any metal, heat is generated; when that current is confined to a smaller cross-sectional area, the heat produced in the entire circuit is ...
Soldering guns are used where more heat is needed than from the lower-power soldering irons. They can be used for heavy electrical connections, stained glass assembly, and light sheet-metal work. Typical soldering guns are rated at 100 to 240 watts power. A gun may include a two-stage trigger to give two heat settings.
The tip of this apparatus is split into two sections that completes an electrical circuit when a low electrical resistance is placed across the tip; e.g. metallic contacts, or solder. [1] With a current flowing, the resistance of both the solder and the tip produces enough heat to increase the temperature beyond the melting point of solder.
A hot air gun or hot air station is used to heat devices and melt solder, and specialised tools are used to pick up and position often tiny components. A rework station is a place to do this work—the tools and supplies for this work, typically on a workbench .

The stubs are then easy to melt off and clean with a soldering iron. Obviously this technique entails the destruction of the IC. Another method is to use a heat gun or pencil butane torch and heat up a corner, and gently pry it off, working the torch down the leads. This method often leads to traces getting lifted off the PCB where a lead did ...
