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.

PERIODIC MAINTENANCE

Calibration of the POWER WAVE
its operation. Generally speaking the calibration will
not need adjustment. However, neglected or
improperly calibrated machines may not yield satis-
factory 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, contact the Lincoln Electric
Company for the calibration software utility.
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. Detailed instructions are available with the
utility.
