We should make a distinction between temperature controlled and non-temperature controlled irons/guns. I have used a Weller TCP 40 watt pencil iron with a wide 700 degree tip to solder ΒΌ" brass bolts ! The big Weller D550 guns (250/325 watt) are not temperature controlled but can make heat a lot quicker.

I also use a 40W Weller with good results.

The 25W do not work well and tend to melt the center
conductor.

I guess I'm contrary, but I find that a 40 watt Weller

tip does just fine. If your tip is too big you just make
a mess trying to
get it down into the holes. I filed down the tip on a 100
watt iron so that
it fits, but it doesn't work any better than the 40 watt
iron and it's
harder to handle. And I do them by the book. Strip,
twist, and solder. I
never found that any of the published helpful hints and
tricks did anything
but make the job harder.
