POWER WAVE F355i (CE)
SAFETY PRECAUTIONS
CAPACITOR DISCHARGE PROCEDURE
1. Obtain a power resistor (25 ohms, 25 watts).
2. Hold resistor body with electrically insulated glove.
DO
NOT TOUCH TERMINALS. Connect the resis-
tor terminals across the two studs in the position
shown. Hold in each position for 1 second. Repeat
for all four capacitors.
3. Use a DC voltmeter to check that voltage is not
present across the terminals on all four capacitors.
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 F355i (CE) is critical
to its operation. Generally speaking the calibration will
not need adjustment. However, neglected or improp-
erly 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 fac-
tory. Generally speaking the machine calibration will
not need adjustment. However, if the weld perfor-
mance 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
resistance load, 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.
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
• Always wear dry insulating gloves.
------------------------------------------------------------------------
EXPLODING PARTS can cause
injury.
•
Failed parts can explode or cause other
parts to explode when power is applied.
•
Always wear a face shield and long
sleeves when servicing.
