MAINTENANCE

WARNING
Safety Precautions
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.

Calibration of the POWER WAVE
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
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 thePower Wave Manager
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. SVM251 VERIFICATION AND
CALIBRATION PROCEDURES includes detailed instructions at
