This application request was brought to Ultraflex Power’s attention by a HVAC company. Their goal was to eliminate their current use of the torch method, as well as remove defects and improve the safety for operators. To start the test, our applications engineer assembled the setup of copper tubing and brass valves. After applying flux to each joint the engineer heated them for 20 seconds. Solder was manually applied after the joints reached 932oF (500o C), and created an even solder around the joints. The use of induction heating was successful in this HVAC application.
