Note: Soldering Ice Machine Evaporator assemblies
Objective:
To heat a section of 3/8" copper tubing along with a 90° elbow for soldering. The copper tubing is to be used in Ice Machine Evaporator Assemblies, and soldering takes place after the tubes have been placed within the assembly. Heating must take place in a channel type coil to provide easy access, once the tubing has been installed. Solder can be manually fed after temperature has been reached.
End Product:
