SAFETY PRECAUTIONS
WARNING
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.

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
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.
