Electric Soldering Iron
From DT Online
Electric Soldering Irons have small Copper tips heated electrically - often via a Lo-Volt transformer. The Copper tips are usually iron-plated to extend their life and are available in various shapes and sizes to suit the work in hand.
Features and Applications
Low power electric Soldering Irons are commonly in the range 15W - 25W and used extensively for electronics work. They are used together with Multi-Core Solder which ensures that a suitable non-corrosive (i.e. often Rosin Based) Flux is supplied alongside the molten soft solder.
Safety Point! Choose a soldering iron with burn-proof silicone cable and use in a well-ventilated area to avoid inhalation of fumes from the Soldering Flux.
Higher power electric Soldering Irons are available for larger work (e.g. up to 500W) but even these may not be able to supply enough heat when working with large pieces of conductive metals - as in Beaten Metalwork for example.
The tip, or ‘bit‘, of all soldering irons must be kept clean and coated with a thin layer of solder - a process known as ‘Tinning’. This is achieved with electric Soldering Irons by regularly wiping them on a wet sponge (often provided as part of a soldering station) then melting on to it a small amount of Multi-Cored Solder.
