The best electronic soldering irons I've used have been 45 watt Wellers
with conical 0.8mm tips - but they weren't cheap, but that was a while
back. The current range are even more expensive and 90 or 120 watt irons.
The best feature of the Weller range is that the temperature control is
nearly failproof, being a magnetic microswitch just behind the tip. There
is a magnet at the rear of the tip. Like all magnets, it loses its
magnetism when heated to its Curie point: this turns the microswitch off.
It turns back on again as the tip drops below the Curie point and regains
its magnetism. IOW you specify a tip by the shape, diameter *and* the
temperature you require.
