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 CE is critical
to its operation. Generally speaking the calibration will
not need adjustment. However, neglected or improp-
erly calibrated machines may not yield satisfactory
weld performance. To ensure optimal performance,
the calibration 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.
