Warning Click here to learn more about the installation of a gas regulator.	Attention: Protective inert gas must be continuously filled throughout during heating in order to protect the graphite crucible and C thermocouple.  The C-type thermocouple is consumable which is not covered under our limited warranty. The Induction Melting System is designed to operate in low-pressure conditions (< 0.02 Mpa Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSIG for safe operation. Click here to learn the installation of a gas regulator. Never heat the furnace while the gas release valve is closed. The pressure gauge must be used during the healing process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSIG to prevent unforeseeable damages.
