different fabrics need different amounts of heat. thinner fabrics tend to be more delicate, so a higher heat setting would damage them, wheras heavier fabrics need more heat to smooth wrinkles effectively. if you have an iron with steaming capabilities, settings can adjust whether or not (and how much) the steam is on.
however high the settings can go on the iron
No, this particular flat iron only offers an on/off switch with one general temperature setting for all.
An iron typically consumes more electricity than a heater. This is because irons have high power requirements to heat up quickly and maintain a constant temperature, whereas heaters generally have adjustable settings for different temperature levels and can operate at lower power settings.
They probably have different settings for different songs.
iron bending different from iron rusting
There are no best settings it's all a matter of opinion I would use different settings for different moods and themes.
The iron may be dribbling water because the water reservoir is overfilled or because the steam settings are too high. Excess water in the iron can leak out during ironing, especially if the iron is moved too quickly or tilted at an angle. Try draining some water from the reservoir and adjusting the steam settings to see if it helps reduce the dribbling.
My Black & Decker Sure Steam iron has a chart on it with suggested settings for different fabrics, and it has a setting for nylon (the second to lowest setting) and suggests not using steam, just a dry iron. I have a 100% nylon mesh blouse that I ironed on this setting, and put a cloth napkin over the area I was ironing to be safe and had no problems.
the angle of the head is different. A 3 iron is not much of an angle, and a 9 iron is like at 50 degrees or so
On most irons, the setting that corresponds to 350 degrees Fahrenheit is typically labeled as "linen" or "cotton" setting. Make sure to double-check your iron's user manual for specific temperature settings, as they can vary between different models.
Density and melting point are different.
