  • Page 7: Putting Into Operation

    2 Putting into operation On delivery, immediately check if the machine is complete and if there are any transportation damages. In the case of damages, please contact at once supplier or forwarding agent. 2.1 Set-up directions The machine should be placed on clean and dry ground. The ground should be even, solid and level.

  • Page 8: Protective Gas (Argon Or Nitrogen)

    2.4 Protective gas (Argon or Nitrogen) Purity to be no less than 99.95% must be used as protective gas. Use a compressed air hose with an inner ø of 6 mm. The inlet pressure must be 8 bars. The machine will start adding protective gas into the inductor housing at temperature higher the 500 °C.

  • Page 9: Safety

    The machine has been developed for use in enclosed spaces and for the above mentioned application. Only original INDUTHERM consumables and spare parts are admitted for operation.

  • Page 15 Danger! Danger for the eyes. Always place the gold coated foil for eye protection against thermal radiation on top of the inspection window of the crucible chamber. In addition wear safety goggles suitable for welding operations Danger! Danger because of touching parts conducting voltage.
  • Page 16 Danger! At crucible temperatures over 100 °C the cooling water supply must be switched on. If it is not turned on, the inductor will be destroyed. If cooling water supply fails, the heating system immediately is turned off. Inspect the system for damage before putting back into operation again.

    Flask (rotary switch): By using this rotary switch, select if the flask is to be evacuated or ventilated. Locked- Standard position to add or remove the flask into the vacuum chamber. Vacuum- After putting in place the flask, the vacuum is turned on.
  • Page 24 Switch on vacuum casting machine and vacuum pump. Grind in the sealing rod into the crucible bottom (rotating movement) Set the desired melting program. Select 'normal’ with the valve ‘crucible’ (standard selection: normal-pressure). If pressure or vacuum is selected, the vacuum chamber must be closed with your flask already inside.
  • Page 25 Release the vacuum with the valve ‘flask’. If the crucible was put under over- or under-pressure, also release it with the valve ‘crucible’ to ‘normal’ position. Lower the vacuum chamber with the valve ‘chamber lift’ and swing out the chamber. Now the flask can be removed.

    12. Vacuum was turned on too late/turned off too early. 13. Contamination in the investment because of wax residues (steam out flasks). 14. Graphite contamination (use ceramic insert or crucible of better graphite quality). Please note that INDUTHERM cannot be held responsible for dissatisfying casting results. page 26...
