ROUTINE MAINTENANCE
Routine maintenance consists of periodically blowing
out the machine, using a low-pressure air stream, to
remove accumulated dust and dirt from the intake and
outlet louvers, and the cooling channels in the
machine.
PERIODIC MAINTENANCE
Calibration of the Power Wave ® C300 is critical to its
operation. Generally speaking the calibration will not
need adjustment. However, neglected or improperly
calibrated machines may not yield satisfactory weld
performance. To ensure optimal performance, the cal-
ibration of output Voltage and Current should be
checked yearly.
CALIBRATION SPECIFICATION
Output Voltage and Current are calibrated at the fac-
tory. Generally the machine calibration will not need
adjustment. However, if the weld performance
changes, or the yearly calibration check reveals a
problem, use the calibration section of the
Diagnostics Utility to make the appropriate adjust-
ments.
The calibration procedure itself requires the use of a
grid, and certified actual meters for voltage and cur-
rent. The accuracy of the calibration will be directly
affected by the accuracy of the measuring equipment
you use. The Diagnostics Utility includes detailed
instructions, and is available on the Service
Navigator CD or at www.powerwavesoftware.com.
