Soldering is a process of joining two pieces of metal by melting a lower-melting-point metal alloy, called solder, into the joint. The solder melts and flows into the joint, creating a strong bond between the two pieces of metal. Soldering is used in a wide variety of applications, including electrical work, plumbing, and jewelry making.
Soldering machines are used to heat the solder and the metal pieces to be joined. There are two main types of soldering machines: gas-powered soldering machines and electric soldering machines. Gas-powered soldering machines use a butane or propane torch to heat the solder and the metal pieces. Electric soldering machines use an electric heating element to heat the solder and the metal pieces.
