The tool you've linked to is no more than a soldering iron with a tip that gets very hot. The temperature and length of time it stays hot depends upon the wattage of the element, A good soldering Iron will normally be in the range of 45 Watts to 65 Watts. The tool you show is only 30 W, not very good at all.
To do what you want, you need is a tool with a separate transformer, with wire tips (Nichrome) which heat (glow cherry red) due to the current flowing through it.
It gets hotter, reheats faster, and will give you the control you need to write.
