Page 4: Introduction
Electromatic - 4 INTRODUCTION The ELECTROM TIC - 4 has been designed and built to consistently produce metallurgical sound precision castings through a series of rigidly controlled operations, automatically or manually performed. Casting with the Electromatic - 4 consists of four basic operations: 1.
Page 5: Installation Preparations
Electromatic - 4 INST LL TION: PREP R TION The following outline has been arranged to provide pertinent information relating to the installation, adjustments and testing of the Electromatic - 4. Strict adherence to these requirements will insure maximum dependable service. Protect the unit from nearby furnace heat with a shield, if necessary.
Page 6 Electromatic - 4 2. SP CE REQUIREMENTS . Floor: 49” (124 cm) wide by 38” (97 cm) deep from wall. The machine base measures 38 1/2” (98cm) by 27 l/2” (70 cm). NOTE: dditional clearances of 10” (25 cm) behind and 5” (13 cm) on each side are required. B.
Page 7 Electromatic - 4 3. ELECTRIC L CONNECTIONS . Connect the cable to the power junction box on the wall according to the local wiring codes. Leave enough slack so the unit can be moved away from the wall for service. The power cable has three wires, Brown and blue will provide the 220 V, and Yellow/green which is GROUND.

Page 9 Electromatic - 4 6. TUBE INST LL TION (Fig. 7) When installing a new tube, turn the Main power switch OFF. (Fig. 11-2) . The tube should be installed in the vertical position with the anode end down. Insert the tube inside strap ( ) and with the fittings (B) facing right, tighten strap ( ) around the tube body.

Page 11: Testing The Unit
Electromatic - 4 The grid current meter should read 400 ma. before making any adjustments, always push the STOP button. NOTE: For more accurate calibration, do not melt the two metal ingots. If the current is higher, using a small screwdriver turn the calibration screw (Fig.
Page 12 Electromatic - 4 OPER TING INSTRUCTIONS To test the operation of the unit, apply the following procedure: (a) Use dummy carbon mold (b) Place approximately 30 grams (1 oz) chrome-cobalt alloy in the crucible djust counter-weight to balance centrifuge (d) Set temperature for 2820°F (1549°C) Set utomatic/Manual key switch to utomatic Set soak Timer for 10 seconds (g) Set Centrifuge cceleration Reducer to 50%...
Page 13 Electromatic - 4 CRUCIBLE SELECTION: The Induction Casting Crucible, Catalog #N031106, should be used for Chrome-Cobalt, Palladium Based, and non-precious alloy castings. When melting gold based alloys, a carbon insert, Catalog #N242903 should be used. C UTION: separate crucible and carbon insert should be identified and maintained for each of the alloys used.
