Induction Soldering Copper Tube With High Frequency Heating Units
Objective: To heat a section of 3/8″ copper tubing along with a 900 elbow for soldering.ย The copper tubing is to be used in Ice Machine Evaporator Assemblies, andย soldering takes place after the tubes have been placed within the assembly.ย Heating must take place in a channel type coil to provide easy access, onceย the tubing has been installed. Solder can be manually fed after temperature
has been reached.
Material: 3/8″ Thin Walled Copper Tubing and 900 Elbow
Temperature: 6000F
Application: Through the use of the DW-UHF-20kWย output solid state inductionย power supply and a unique three (3) turn channel coil, the following resultsย were achieved:
6000F was reached in 10 seconds.
A quality solder joint was observed with adequate flow and surfaceย texture.
Equipment: DW-UHF-20kW output solid state induction power supply includingย one (1) remote heat station containing one (1) 1.2 ฮผF capacitor, and a uniqueย three (3) turn channel coil.
Frequency: 200 kHz
