Soldering gun Soldering gun's parts Spool of solder. 1.6mm. A soldering gun is an approximately pistol-shaped, electrically powered tool for soldering metals using tin-based solder to achieve a strong mechanical bond with good electrical contact. The tool has a trigger-style switch so it can be easily operated with one hand.

Soldering and brazing are thought to have originated very early in the history of metal-working, probably before 4000 BC. [2] Sumerian swords from c. 3000 BC were assembled using hard soldering. Soldering was historically used to make jewelry, cookware and cooking tools, assembling stained glass, as well as other uses.
Pin brazing is a metallurgically safe [citation needed] method of making electrical connections [1] to steel and ductile iron pipelines [citation needed] as well as other metallic structures, [2] which are to be cathodically protected or electrically earthed.
A soldering iron stand keeps the iron away from flammable materials, and often also comes with a cellulose sponge and flux pot for cleaning the tip. Some soldering irons for continuous and professional use come as part of a soldering station, which allows the exact temperature of the tip to be adjusted, kept constant, and sometimes displayed.
A resistance decade box or resistor substitution box is a unit containing resistors of many values, with one or more mechanical switches which allow any one of various discrete resistances offered by the box to be dialed in. Usually the resistance is accurate to high precision, ranging from laboratory/calibration grade accuracy of 20 parts per ...
A ColdHeat soldering iron. ColdHeat was an American company founded to develop and market products using the proprietary graphite-like compound Athalite.The composite material is claimed by the manufacturer to have the unusual ability to conduct large amounts of heat and return to room temperature in a short amount of time.
In such application, where the gun layout should be as rigid as possible due to the high applying forces (e.g. welding of thick materials), the C-type gun is widely used. As well as the high resulting rigidity, this arrangement leads to a high tooling flexibility, as the motion of the electrodes is collinear.
