5. OPERATION DISTURBANCES

In case of problems contact the Kemppi works in Finland or your Kemppi dealer.
Check the maintenance objects before the machine is sent to the service repair shop.

Operation of the overload protection

overheating of machine.
The thermostat of machine will operate, if machine is continously loaded over rated values or

cooling air circulation is blocked.
Cooling fan cools down the machine and when the pilot lamp is not lighted the machine is auto-

matically ready for welding.

Control fuses

devices X14.
Use same type and rating of fuse which is marked beside the fuse adapter. Damage caused by a

wrong type fuse is not covered by the guarantee.

Under- and overvoltages in the mains supply

Primary circuits of machine are protected against sudden, transient overvoltages. Machine is

designed to withstnad 3 x 440 V voltage continously (see technical data: 415 V +6%). See to

it that voltage is kept within admissible limits especially when mains supply is taken eg from

combustion engine generator. If the mains has undervoltage (under ca 300 V), machine control

stops to operate automatically.

Loss of a phase causes noticeable poorer welding properties than normally or the machine

doesn´t get started at all. Loss of a phase can be due to following:
- blowing of mains supply fuse
