6. OPERATION DISTURBANCES
Should you experience a malfunction from your machine, please consult the basic
troubleshooting text above first, and complete some basic checks.
If the machine malfunction cannot be corrected with these measures, contact your Kemppi
maintenance service workshop.
Operation of the overload protection
Yellow thermal protection lamp is lit when the thermostat is operating due to loading beyond
the stated duty cycle.
The thermostat will operate, if machine is continuously loaded over rated values or cooling air
circulation is blocked.
Internal fans will cool the machine, and when the pilot lamp is not lit the machine is
automatically ready for welding.
Control fuses
Fuse, 6.3 A delayed, on the rear wall of machine provides protection for auxiliary devices.
Use the same type and rating of fuse as marked beside the fuse adapter. Damage caused by
incorrect fuse selection is not covered by the guarantee.
Under and over voltages in the mains supply
Primary circuits of the machine are protected against sudden, transient overvoltages. The
machine is designed to withstand 3 x 440 V voltage continuously. Ensure that voltage is kept
within this permissible limit, especially when the mains supply is provided by a combustion
engine generator. If the mains has under voltage (under approx. 300 V) or overvoltage (over
approx. 480 V) machine control stops operation automatically.
Loss of a phase in the mains supply
Loss of a mains power phase causes noticeably poor welding properties. In some cases the
machine won't start at all. Loss of a phase can be due to following:
• Blowing of mains supply fuse
• Defective mains cable
• Bad connection of mains power cable on machine terminal block or plug of machine.
