SAFETY PRECAUTIONS

WARNING
ELECTRIC SHOCK can kill.
• Only Qualified personnel should
perform this maintenance.
• Turn the input power OFF at the disconnect
switch or fuse box before working on this
equipment.
• Do not touch electrically hot parts.
ROUTINE MAINTENANCE
Routine maintenance consists of periodically blowing
out the machine, using a low-pressure airstream, to
remove accumulated dust and dirt from the intake and
outlet louvers, and the cooling channels in the
machine.
The rear portion of the machine that contains the filter
and the cooling fans slides out for easy access.
Removing the four(4) clips and pulling back on the
rear portion of the machine will provide access for
cleaning the machine and checking the filter. The filter
may be removed from the right side of the machine.
See Figure A.1.
PERIODIC MAINTENANCE
Calibration of the Power Wave
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 calibration of output Voltage
and Current should be checked yearly.

CALIBRATION SPECIFICATION

Output Voltage and Current are calibrated at the
factory. Generally speaking 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
Weld Manager Utility to make the appropriate
adjustments.
The calibration procedure itself requires the use of a
grid (Resistive Load Bank), 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 Weld
Manager Utility includes detailed instructions, and is
available on the internet at powerwavesoftware.com
under Power Wave Submerged Arc Utilities.
