Fusamura |

To make it easier to understand,
we will classify soldering irons into
two types: "Temperature saturation
type" and "Temperature control type". |
| Hikaru |
: |
This seems to difficult to understand. What
is the difference between these two types? |
| Mr. Fusamura |
: |
First, I'll talk about the
"Temperature saturation type".
The maximum amount of current flows through
this type of soldering iron; In other
words, it is always "ON". |
| Hikaru |
: |
I see! Then,
the iron temperature must increase without
limit. I don't want such hazardous soldering
iron. |
| Mr. Fusamura |
: |
Ha-ha-ha
(Laughing). Now, look at this graph.
When the temperature saturation type soldering
iron is energized, the iron temperature
will increase to a certain temperature and
then will not increase any more. This temperature
is called the "saturation temperature",
which is the specified operating temperature
of the soldering iron.
|
| Hikaru |
: |
You mean the iron temperature
will not increase without limit. Why?
