MAINTENANCE

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 455M (CE) is critical to
its operation. Generally speaking the calibration will
not need adjustment. However, neglected or improper-
ly calibrated machines may not yield satisfactory weld
performance. To ensure optimal performance, the cali-
bration of output Voltage and Current should be
checked yearly.

CALIBRATION SPECIFICATION

Output Voltage and Current are calibrated at the facto-
ry. 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
resistive load bank, and certified actual meters for volt-
age 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.
