1. Introduction 1.1. General description of the MU melting machines With this melting machine, the melting charge is heated up by induction. The special advantage of inductive heating is that the melting temperature is reached rapidly, because the heat is directly generated in the metal and in the crucible. During the melting process, the metal is thoroughly mixed by means of a magnetic field, ensuring a homogenous mixing even when using new alloys.
1.3. Technical data MU200 MU200 single phase three phase 2,3 kg/Au Crucible volume 155cm Useable capacity 75% of maximum volume Crucible temperature max. 1200 °C max. 1400 °C Melting performance 3,5 kW 6,0 kW 3 * 400 V/16A, 50 or 60...
1.4. General information Safety information In order to ensure a constant, ideal performance of the machine and to ensure safe working conditions, the user is to observe the following safety measures: The complete electrical wiring is to be performed only by qualified and specially trained personnel.

(maximum) from the nominal value. The mains supply must at least be furnished with 20 A and maximum with 32 A delay-action fuses (at 3* 400 V AC). The machine is equipped with a 32 A-Ceekon-connector when leaving INDUTHERM. All 5 lines (L1, L2, L3, N, PE) must be connected correctly.
3. Operation 3.1. Operating elements Temperature: Normally, the actual crucible temperature is indicated here. When pressing the buttons “+” or “–“ the indication changes to the set-point value (nominal value) for at least 5 seconds. An active set-point value is indicated through an illuminated red decimal point. The set-point value can be altered with the buttons “+”...
Power: -Button Start / Stop: The generator is turned on/turned off with this buttons. The turned on generator regulates principally to the adjusted nominal temperature (see Crucible-Temperature). -Button + / -: The maximum generator power is selected with this buttons At the side of the operating panel: Mains Switch: The machine is switched on/off by turning the mains switch.
4. Service 4.1. Trouble shooting Only trained personnel should open the machine. The machine cannot be turned on: - when there is no mains supply The heating cannot be turned on: - when there is no cooling water supply, error code “E012” - when thermocouple is not in place or defective, indication crucible temperature “OFbE”...
4.2. Maintenance A routine check/regular cleaning of the following is necessary: (Caution: disconnect the machine first!): Daily (before casting): 1. Remove thermocouple, crucible and insulation materials, carefully clean inductor housing with a vacuum cleaner. Before reinstalling the above parts, check those and replace if necessary.
Consumables and spare parts list At following side the spare parts list for this machine will start. INDUTHERM is now using only machine specific spare parts lists, which contain all the information for your machine. The name is encoded.
