7. MAINTENANCE
When considering and planning routine maintenance,
please consider the frequency of machine use and the
working environment.
Correct operation of the machine and regular maintenance
will help you avoid unnecessary downtime and equipment
failure.
Disconnect the machine from the mains before
handling the electrical cables.
7.1 Periodic maintenance
Periodic maintenance should only be carried out by
a suitably qualified person. Disconnect the plug of the
machine from the mains socket and wait about 2 minutes
(capacitor charge) before removing any parts.
Check at least every half year:
• Electric connectors of the machine – clean any
oxidized parts and tighten loose connections.
Do not use compressed air for cleaning as there is a
risk that the dirt will compact even more tightly into gaps of
cooling profiles.
Do not use pressure washing devices.
Only an authorized trained electrician should carry out
repairs to Kemppi machines.
7.1.1 Factory and field calibration
Kemppi calibrates each system using instrumentation
traceable according to ISO 9001. All instruments are
checked for accuracy by independent laboratories at
scheduled intervals. We recommend that equipment is
recalibrated every twelve (12) months. You may recalibrate
the power source and weld heads if proper instruments
are available (with traceable calibration). Contact the
factory if necessary.
7.2 Weld head maintenance
7.2.1 Calibrating the weld head
The 150 series controller software allows users to calibrate
the travel speed for 150 series of weld heads. Weld heads
supported by the 150 series controller software utilize
built‐in encoders for motor control while some others may
use a tachometer. The encoder‐based heads offer better
control of the travel, and therefore little or no adjustment
is required during the calibration process. Tachometer‐
based heads usually require adjustment each time they
are calibrated.
Kemppi recommends that the travel speed are checked
once daily to ensure accuracy.
To calibrate the head, press
Menu
in the Main menu to
enter the Maintenance menu. Once in the Calibrate Head
menu, do the following:
1. Select the model of the weld head to be calibrated.
2. Use
Up/Down
to navigate within the menu and
Enter to make a selection.
3. If this is the first time calibrating a particular weld
head or you see “Calibration Out of Range” error
message, press
Default
after selecting the weld
head to install the factory setting for the correction
factor.
4. Select
Travel Speed
to calibrate.
5. For travel calibrations, choose the
Distance to
Travel
or
Desired RPM
by rotating the dial and press
Enter
.
6. Press
Run
and measure the actual amount traveled
or actual run time (or the length of wire).
7. Enter the measured value and press
Save
.
8. Repeat this process until you have achieved
desired accuracy, then press
Back
to return to the
Maintenance menu.
