You can use soldering stations and irons for various tasks, most of which require a controlled heat source. However, this puts the iron at risk of damage and makes it less possible to use for its original requirement.
The various alternative things that a soldering iron is used for plastic-welding, which uses iron to melt and/or join plastic, hot-wire foam cutting for cutting through foam with a heated wire, Pyrography, which is more common than most people think.
Pyrography, which is also known as pokerwork or wood burning, literally means “writing with fire” and is basically a traditional art of decorating wood or other materials with burn marks, using a heated tip or wire to burn designs and lettering onto materials, mostly wood and leather. This burning type can only be done using a solid-point tool, which is very similar to a soldering iron.
This method enables the welder to use various tones and shades by varying the type of tip used, the temperature it is set at, and the technique the iron is used on the material to create specific effects.
Solid-point soldering stations like PACE ADS200 can come with various tip shapes, which you can use for branding on wood and leather. Then you have the wire-point soldering stations that let the creator adjust the form of the wire accordingly to achieve either thick marks or thin lines. This kind of work does take a lot of skill and time as it is predominantly done by hand. Once the design is burned in, wooden objects can and often are colored.
The type of wood that is usually used is light-colored wood like Beech, Birch, and Sycamore, as they tend to produce perfect contrast. When required, Pine and Oak are also used. Using a similar branding technique, the same is also applied to leather, which allows subtle shading to be achieved as well.
What is also very important when soldering nonmetallic items like wood and leather is that you must heat the soldering bit for just the right amount of time. This is essential to the quality of the work as excessive time would damage the material. Heating the surface with the tip of the iron while continuing to heat while soldering is the best way, although you would ideally suit someone with a great deal of soldering experience to carry out such a task, always bearing in mind the heating period, the surface and the application.
