The hand piece assembly needs to absorbe the majority
of the heat or at least this is how Pace makes thier
units.
Here is a quick diagram:

hollow tube made of rubber
The hollow rubber tube slips inside of a hand piece
that the tip/heating element is permenately connect
to. The rubber hose slips in from the back and is
pushed upto the hot tip. There is a high temp seal
that creates an air tight bond between the hose and
the hand piece / hot tip. Inside of the rubber tube, a
there is a piece of aluminum sheet that has been bent
into the shape of an "S". It is placed directly behind
the hot tip. Behind the aluminum sheet that is in the
shape of an "S", is a cotton fiber plug. There is an
inline filter in the hose about 3 feet from the hand
piece.
The aluminum sheet in the shape of an "S" is
removeable so that it can be cleaned. It catches the
hot, liquid solder and cools it. The majority of the
solder hardens on to it. Whatever solder does not
stick to it forms balls and fall to the back of the
tub up against the cotton fiber plug.
You clean the unit with WD-40 (Everything except the
hot tip.). This removes all rosin from the rubber tube
and the various pieces inside of it. You have to
change out the cotton fiber plug and the filter paper
and clean the unit (In the inline filter) after about
every 8 hours of use.
I can take pictures of the unit assembled and
dissassembled if you would like what it looks like.
