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
Yellow pilot lamp H12 of thermal protection is lighted when thermostat has operated due to
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
Fuse F11, 1,0 A delayed, on the rear wall of machine is as protection for connection of auxiliary
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 in the mains supply
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
- defective mains cable
- bad connection of mains connection cable on terminal block or plug of machine.
