I have a question. What is the electric soldering machine? I never
looked it in Japan.
I searched about it in the orchid archives, and I’m imaging that it
has two terminal arms connected with the body by wires. One terminal
is made by some metal that doesn’t have electric resistance, and the
other is made by carbon with resistance. When the two terminals are
attached to metal, current heats the carbon terminal and the heat
melts the solder.
Is my image right? If it’s incorrect, would you tell me what is the
electric soldering machine and how it works.
If my image is correct, I have another question. The solder flows to
the hotter place, so the geometry of the solder and the carbon
terminal must be carefully decided. How do you arrange?
