NOTE!
Watch out for mains voltage when handling electric cables!
Degree and circumstances of machine utilisation should be taken into consideration when
planning product maintenance. Careful use and preventive maintenance helps to avoid
unnecessary production disturbances and breaks. Check the condition of the welding and
connection cables daily. Do not use damaged cables.
4.1 regular maintenance
4.1.1 every six months
NOTE!
Disconnect the plug of the machine from the mains socket and wait for about 2 minutes
before removing the casing plate.
the following maintenance operations should be carried out at least every six months:
• Electric connections of the machine – clean any oxidised parts and tighten any loose
ones.
NOTE!
You must know the correct tension torques before you start repairing the connections.
• Clean the inner parts of the machine from dust and dirt e.g. with a soft brush and a
vacuum cleaner. Do not use compressed air because there is the danger that the dirt
is packed even more tightly in the gaps of the cooling profiles. Do not use a pressure
washer.
NOTE!
Only an authorised electrician may repair the machine.
NOTE!
The machine and control panel are at mains current potential. DO NOT remove either the
cover or control panel unless authorised to do so. Only authorised and trained personnel can carry
out maintenance and repair processes.
4.2 service contract
Kemppi service workshops make special service contracts with customers about regular
maintenance. All parts are cleaned, checked and if necessary, repaired. Also the operation of
welding machine is tested.
4.3 storage
The machine must be stored in a clean and dry room. Protect the machine from rain and direct
sunshine in places where temperature e25 °C.
