• WARNING:
• The flow rate of gases should be limited to < 200 SCCM (200 ml/min)
• The Melting System are designed for using under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 psi. Gas build-up with pressure levels exceeding 3 PSI may cause irreversible damage to the furnace chamber.
• A pressure regulator must be installed on your input gas tank
• The output gas pressure must be 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 heating.
• Open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damage.

• Attention: 
  Understand the standard procedure for vacuum melting and inert gas melting before operation. Read the manual carefully. Monitor and properly control the inside pressure of the reaction vessel at all times during operation. Otherwise, failure of operation may result in irreversible damage to the equipment or personal injury
