It is forbidden to attempt to repair damaged electronic boards or modules; replace them with original Cebora spare parts. 1.3 - Safety informations. The safety notes provided in this manual are an integral part of those given in the Instruction Manual.
2 - SYSTEM DESCRIPTION 2.1 - Introduction. The TRI STAR MIG 1635/M is a multiprocess system for MIG/MAG, TIG-DC and MMA welding. It is made up of an electronic power source (art. 283) and a set of accessories to adapt to various types of applications (see list in the Sales Catalogue).

CEBORA S.p.A. − two 3-digit displays to show output voltage, welding current, wire speed, values assignable to the selected parameters, material type, services functions and error codes. The welding current regulation is performed by the microprocessor on the control board (29), based on signals received from the power board (32), and parameters set via control panel.
CEBORA S.p.A. 3 - MAINTENANCE WARNINGS ANY INTERNAL INSPECTIONS OR REPAIRS MUST BE CARRIED OUT BY QUALIFIED PERSONNEL. BEFORE BEGINNING MAINTENANCE OPERATIONS, UNPLUG THE MACHINE FROM THE MAINS AND WAIT FOR THE INTERNAL CAPACITORS TO DISCHARGE (2 MINUTES). 3.1 - Periodic inspection, cleaning.
♦ After three seconds, leds and displays lit (lamp test). Fans (27) working. ♦ After one second, display (M) indicates the Cebora article number (i.e.: “283”). ♦ After one second, display (M) indicates the version of the programs related to the synergic curves (i.e.: “H01”, H = synergic programs table, 01 = programs...
CEBORA S.p.A. Correct? NO (see 3.3.3). 3.2.3 - MIG operation. NOTE On continuation it is illustrated the sequence of MIG process only, which involves all the circuits of the power source, and therefore is considerate sufficient for the purpose of this manual.
CEBORA S.p.A. 3.3 - Troubleshooting. WARNINGS ANY INTERNAL INSPECTIONS OR REPAIRS MUST BE CARRIED OUT BY QUALIFIED PERSONNEL. BEFORE REMOVING THE PROTECTIVE GUARDS AND ACCESSING INTERNAL PARTS, DISCONNECT THE POWER SOURCE FROM THE MAINS AND WAIT FOR THE INTERNAL CAPACITORS TO DISCHARGE (2 MINUTES).
♦ See Error codes and alarm signals, par. 3.4. INDICATORS TEST. Upon start-up, after the lamp-test, display (M) indicates the Cebora article number (i.e.: “283”). After one second, display (M) indicates the version of the programs related to synergic curves (i.e.: “H01”, H = synergic programs table (short), 01 = programs version);...
CEBORA S.p.A. Correct? ♦ Check the wiring between J1 control board (29) and J1 power board (32). ♦ Check the wiring between J3 and J7 control board (29) and J4 power board (32). ♦ Carry out the CONTROL BOARD (29) POWER SUPPLY TEST, par. 3.3.1.
CEBORA S.p.A. ♦ Check the wiring between terminals J8 and J9 of power board (32) and solenoid valve (7). ♦ With the power source off, check the resistance on solenoid valve (7) terminals = 2500 ohm. If 0 ohm (short-circuit), replace solenoid valve (7) and power board (32).
CEBORA S.p.A. 3.3.7 - In open circuit operation, the output voltage is not regular. OPEN-CIRCUIT OUTPUT VOLTAGE TEST. Output terminal –(G) power source (-) and output terminal +(H) power source (+) = voltages per table: Process Voltage Condition +109 Vdc...
CEBORA S.p.A. 3.3.8 - In resistive load operation, the output voltage is not regular. OPEN-CIRCUIT OUTPUT VOLTAGE TEST. Output terminal –(G) power source (-) and output terminal +(H) power source (+) = voltages per table: Process Voltage Condition +109 Vdc...
CEBORA S.p.A. ♦ Replace power (32) and/or control (29) boards. ♦ Check connection between diode group heat sink on power board (32), inductor (28) and power source +(H) output terminal, and between TP9 on power board (32) and power source –(G) output terminal.
CEBORA S.p.A. 3.4 - Error codes and alarm signals. 3.4.1 - 02 - EEPROM error. Block due to software error. Replace the control board (29). 3.4.2 - 10 - Malfunction in the circuit to detect short-circuits at the output. Upon power source start-up this test checks the operating conditions by performing a brief test to generate the open-circuit output voltage.
CEBORA S.p.A. 3.4.6 - 54 - Short-circuit between torch and workpiece upon start-up. Upon power source start-up this test checks the operating conditions by performing a brief test to generate the open-circuit output voltage. While this is taking place it is important that the torch not touch the workpiece or welding bench.
CEBORA S.p.A. 3.4.9 - 61 - Mains voltage lower than minimum limit. 3.4.10 - 62 - Mains voltage higher than maximum limit. The control board (29) verifies the mains voltage by means the +24 Vdc supply voltage check. If the mains voltage results suitable, the power source gets ready for the operation; if instead it is judged too low, the control commands the block for error 61, if too high commands the block for error 62.
