PROBLEMS

(SYMPTOMS)

The INVERTEC® V450-PRO does not have welding output. The main input contactor (CR1) is not activating.

NOTE: This problem will normally be accompanied by an error code.

The Diagnostic Utility is also available on the Service Navigator.

POSSIBLE AREAS OF

MISADJUSTMENT(S)

OUTPUT PROBLEMS

1.The input voltage may be too high or too low or reconnect panel may be incorrectly connected

2.May be a thermal shutdown. Check to see if the Thermal LED is ON

3.The primary current limit has been exceeded (CR1 drops out when the output is initiated).

4.The power source (upper section) has failed. If nothing is evident from a visual inspection, perform tests as shown.

NOTE: Error codes as indicated by LED 9 and 10 on the Control Board.

RECOMMENDED

COURSE OF ACTION

1.Make certain that the input voltage is proper, according to the Rating Plate located on the rear of the machine. See Installation Section of this manual.

2.See Thermal LED is ONin this section.

3.Possible short in output circuit. Turn machine off. Remove all leads from the output of the machine.

4.Perform the Input Contactor Test.

5.Perform the Input Board Test.

6.Perform the Auxiliary Transformer test for T-1

7.Preform the Input Rectifier test.

8.Perform the IGBT Switch Board Test.

9.Perform the Power Board Test.

10.Perform the Control Board Check. The Control Board may be faulty.
