More heat, yes. Higher temperature, no. Big difference.

If you have a point of use item like a small soldering iron it isn't
necessary to heat the lead solder up to a higher temperature. But if
you have a larger vessel to get heated up, you are going to have to
use a more heat which will result in a higher temperature at some
places in the pot. And if you use something like a cutting torch, it
will give you more heat and also make things hotter. So more heat
being applied WILL result in higher temperatures than less heat.
