Application Notes
Click here to learn more about the installation of a gas regulator.
|
- Please click here to learn the Fundamentals of Induction Heating
- The Induction heating system is designed for use under vacuum and low pressure < 0.02 MPa.
-
Attention: A pressure regulator must be installed on your input gas tank ( click picture below to review ) and have the output gas pressure set below 3 PSI at all times after opening the gas tank with the gas maintained in a continuous flowing condition.
- Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the healing process
- The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min )
