3.6 ERROR CODES

The machine always checks its operation automatically during start-up and reports any

failures detected. If failures are detected during start-up, they are shown as error codes on the

control panel display.

Err3: Overvoltage or undervoltage

The machine has stopped the welding because it has detected momentary voltage spikes or

continuous mains over- or under-voltage dangerous to the machine. Check the quality of the

supply network.

Err4: Power source overheating

The power source has overheated. The cause may be one of the following:

• The power source has been used for a long time at maximum power.

• The circulation of cooling air to the power source is blocked.

• The cooling system has experienced a failure.

Remove any obstacle to air circulation, and wait until the power source fan has cooled down

the machine.

4. MAINTENANCE

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 help 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 sixth months

NOTE! Disconnect the plug of the machine from the mains socket and wait for ca. 2 minutes

(capacitor charge) before removing the casing plate.

The following maintenance operations should be carried out at least every sixth

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 proles. Do not use a pressure

washer.

NOTE! Only an authorised electrician may repair the machine.

4.1.2 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.
