What is a soldering iron? What's the difference between soldering iron and soldering tin?

What is a soldering iron? Use an electric soldering iron (formerly' soldering iron') to dissolve the solder and stick it on the welded part, so that the two parts are connected into one. This method needs the help of some flux.

What is "solder immersion"? As the name implies, put the weldment into the tin can, then take it out, the solder enters the gap, and the weldment is in close contact.

What's the difference: different ways lead to the same goal, different methods, different means, and choice as needed.

For example, in order to solve the hidden trouble that the quality and time of the' hidden wire' joint in the wall are long, in order to avoid the maintenance of the wall, the process of' hanging tin' is adopted on the joint. At this time, it is not correct to hang tin and electric soldering iron with a tin pot.
