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.
Soldering (US: / ˈ s ɒ d ər ɪ ŋ /; UK: / ˈ s oʊ l d ər ɪ ŋ /) is a process of joining two metal surfaces together using a filler metal called solder. The soldering process involves heating the surfaces to be joined and melting the solder, which is then allowed to cool and solidify, creating a strong and durable joint.

The Galion Iron Works Company of Galion, Ohio, was founded by David Charles Boyd and his three brothers in 1907. In its early years, the Galion produced a wide range of road-building and other construction equipment, such as drag scrapers, plows, wagons, stone unloaders, rock crushers, and a variety of other "experimental machines".
Solder used in making electrical connections also needs to have favorable electrical characteristics. Soft solder typically has a melting point range of 90 to 450 °C (190 to 840 °F; 360 to 720 K), [3] and is commonly used in electronics, plumbing, and sheet metal work.

Then, the needle gun is used to remove rust, loose scale, and paint, leaving bare metal. [5] It is used most effectively by holding it at a 45° angle to the work surface. [5] It is recommended that an area no larger than 6 to 8 inches (150 to 200 mm) be cleared at once. [5] Two to three passes over an area is generally sufficient to clean it. [5]
