A soldering gun is a type of soldering iron that uses a heated metal tip to melt solder, which is a metal alloy with a low melting point. The solder flows between the metal parts to be joined, creating a strong electrical connection.
Soldering guns are typically used for large or heavy-duty soldering projects, such as repairing electrical appliances or making jewelry. They are also sometimes used in construction and plumbing applications.
Soldering guns come in a variety of wattages, with higher-wattage guns providing more heat and being better suited for larger projects. They also have different tip sizes, which are chosen depending on the size of the solder joint being made.
When using a soldering gun, it is important to wear safety glasses to protect your eyes from hot solder and sparks. You should also use a heat sink to protect the workpiece from heat damage.
