Test 2 – voltage balance

Test to check the balance of the bus voltage, the power-factor circuit, and the soft-start circuit.

• Verify the system’s serial number. Serial numbers lower than 1000-016236 have a different power board

from systems with serial numbers higher than 1000-016236.

• Remove screws from capacitors C94 and C98 before measuring the resistors listed below.

• Check the voltage across the inverter IGBT (Q6).

• Check the voltage across the capacitors (C94, C98) before and during torch operation.

• Voltage across both capacitors should be 375 VDC.

On systems with serial numbers below 1000-016236, if the capacitors are not balanced at 375 VDC, install the
RCD resistor kit (PN 128963). For systems with higher serial numbers, replace the power board.

Note:

All values can be ±15%.
