STORY 2: "Heat value is like a water"

I understand. The desired water level is the temperature indicated on the soldering iron!

That's right. There is another type of soldering iron, called the "station type". It provides a separate temperature control unit, but uses the same principle as the temperature control types. But, since the station type soldering iron can set the soldering tip to a desired temperature, it is applicable to a wide range of soldering conditions, from those requiring a large amount of heat to those inhibiting a large amount of heat.

Hmm. You mean that there is a difference between soldering irons with the same temperature rating of 300ºC. That is, the temperature saturation type reaches 300ºC at its full capacity, but the temperature control type reaches 300ºC with remaining capacity and allows a further temperature rise.

You have understood it thoroughly. That's it. The advantage of the temperature control type is that it enables accurate temperature control and that the heater's "W" value is large. Therefore, the temperature control type can reduce the time required for the soldering tip to reach a preset temperature and the time to recover preset temparature. Thus, this type of soldering iron is useful for continuous work. But, the temperature saturation type can work well if you need neither accurate temperature control nor continuous work.

Which type of soldering iron is suitable for me?

To solder wiring, I recommend "HAKKO RED" rated at 20 to 40 W. But, if you intend to use the soldering iron for precision electronic components such as ICs in the future, "HAKKO DASH" rated at 15 to 25 W may be preferable.

Hmm, Well, I'll select the "HAKKO DASH" 20 W. I suppose that it can be used for various purposes.
Can you suggest what I should buy in addition to this?

Let me see. You must buy an iron holder, because it is dangerous to put a hot soldering iron directly on the table. This is an iron holder with cleaning sponge. It is useful for wiping solder residue off the soldering tip. As well, you should buy a desoldering wire in case of erroneous soldering. You can suck up solder with this tool.

Which type of solder should I buy?

I recommend this solder called "HEXSOL". The solder diameter should be 0.6 to 1.0 mm for electronic handicrafts, and 1.2 to 2.0 mm for metal processing. Therefore, in your case, solder with 0.8 or 1.0 mm diameter is preferable.

Well, I'll buy this solder with 1.0 mm diameter. By the way, do you have some spare time right now?

You would like me to come with you, wouldn't you?

How did you guess? (Laughing)

These two people will now go to Hikaru's home.
