Soldering irons are hand tools most often used when soldering or welding. Their primary function is to provide heat, which in turn melts the solder and allows it to flow through the joints between two different work pieces, effectively joining them. A gas soldering iron is generally composed of material that has a heated tip and a very insulated handle to protect the hands. Heating can be achieved through the passage of an electrical current through a resistive material, but the more common method includes the combustion of gas which is either transmitted through a tank attached to the iron, or directly through and unprotected flame.
Gas soldering irons are generally used for brazing, welding or, occasionally, for burning designs into wood and engraving. They are relatively easy to use, gas especially, since it only involves holding a button while angling the fire at the two pieces to be welded. However, easy as they may be to use, they should not be used lightly or given to children. Mistakes or careless use can easily result in physical harm. Good ideas for safety are wearing gloves and always having goggles as well as a bowl of cool water to put your fingers in if they for some reason become burned (this is not recommended for those using an electric one, as any water near electrical tools is a greater risk than asset).

Buying a gas soldering iron is a relatively simple process. You can find a large selection for sale online. For those that feel they need more help in finding the right one for their projects, going to a local tool shop can be a great help-the sales staff should be able to answer any questions you might have and find the right iron for your needs. They can also give more specific pointers on safety and usage once you have made your selection.
