Mr. Fusamura

OK. But I am not an expert either. First, heat up both the lead wire and the terminal, and then feed the solder. After feeding an appropriate amount of solder, stop feeding the solder. After the solder spreads well, pull the soldering iron from the joint. How is that? (Photo 7)

That's really great.

Mr. Fusamura

After finishing work, let's put the tools away. To put the soldering iron away, first thoroughly wipe off the solder adhering to the soldering tip with the cleaning sponge and then feed fresh solder to the soldering tip. (Photo 8) This can prevent the soldering tip from being oxidized, ensuring a long service life. (Photo 9)

Clean the soldering tip. Apply fresh solder to the soldering tip.

I see.

Mr. Fusamura

Then, be careful not to put the solder and the soldering iron within a child's reach. After putting the tools away, clean your hands thoroughly. Solder contains lead and it is not good if lead enters the body.

Hikaru

The soldering iron is a tool that can be used by anyone but it must be handled with care. Now, I'm getting interested in soldering.
