The mass of the large tip is the reason that an iron is best for that kind of work. It naturally transfers the heat more efficiently.
I have a real serious old iron, a 300 watt American Beauty. It is made for the likes of sheet metal work. The copper tip is at least 1" in diameter and really gets hot.
The old fashioned kind that has to be heated in a gas flame is called a "soldering Copper".
