If this is your soldering iron:

As BAW says, its rebadged in many forms. Another common copy is Vellemans:

The only thing good about it is its cheap. I wouldn't buy any accessories. A good soldering iron has true temperature controlled feedback, and typically run about $50. What you have here is a resistance heating rod [ like you have in a stove] with variable heat provided by a light dimmer.
I'd suggest you find a Weller in the EU or UK with the specs of the Hakko FX888 or the Weller WES51; these are the most basic. Weller because the EU versions are often made in Germany and you'd unlikely be as heavily taxed as a Hakko. US specific low cost Weller model are commonly made in Mexico. You can also find the Xytronic equivalent, which is far cheaper but insure you can return it as the quality control can be variable.
