This gas soldering iron from Draper Tools is a very helpful device for soldering.

The unique pen-shaped design makes it compact, lightweight and convenient and it is cordless because it is gas powered. It has instant electronic ignition, variable flame control and a refillable tank. Continuous work can be realised in the medium setting. Standard butane lighter fuel will give a working time of up to approximately 20 minutes. It is easy to refill and gets hot fast. You can handle it with just one hand, which makes your work easier.
