MAINTENANCE POWER WAVE ® R500
SAFETY PRECAUTIONS
WARNING
ROUTINE MAINTENANCE
Routine maintenance consists of periodically blowing out the
machine, using a low-pressure air stream, to remove accumulat-
ed dust and dirt from the intake and outlet louvers, and the cool-
ing channels in the machine.
PERIODIC MAINTENANCE
Calibration of the POWER WAVE ® R500 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 perfor-
mance, the calibration of output Voltage and Current should be
checked yearly.
CALIBRATION SPECIFICATION
Output Voltage and Current are calibrated at the factory.
Generally the machine calibration will not need adjustment.
However, if the weld performance changes, or the yearly calibra-
tion check reveals a problem, use the calibration section of the
Diagnostics Utility to make the appropriate adjustments.
The calibration procedure itself requires the use of a grid, and
certified actual meters for voltage and current. 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 .
ELECTRIC SHOCK can kill.
•Do not operate with covers
removed.
•Turn off power source before
installing or servicing.
•Do not touch electrically hot
parts.
• Turn the input power to the welding power
source off at the fuse box before working in the
terminal strip.
• Only qualified personnel should install, use or
service this equipment.
