Operation Manual

3.4 DISPOSAL OF THE MACHINE

Do not dispose of electrical equipment with normal waste!

In observance of European Directive 2002/96/EC on waste electrical and electronic

equipment, and its implementation in accordance with national law, electrical equipment

that has reached the end of its life must be collected separately and taken to an appropriate

environmentally responsible recycling facility.

The owner of the equipment is obliged to deliver a decommissioned unit to a regional

collection centre, per the instructions of local authorities or a Kemppi representative. By

applying this European Directive you will improve the environment and human health.

4. TROUBLESHOOTING

In the event of a failure of the machine, contact an authorised Kemppi service agent. Before

taking your unit for servicing, check the list below.

4.1 OVERLOAD YELLOW INDICATOR LIT

Two simultaneously operating fans cool the power source. The machine may, however,

overheat if continuously loaded above the rated values or if the circulation of cooling air is

prevented.

Overheating is indicated by a yellow indicator light in the front panel of the power source. You

then need to stop welding and let the machine cool down. The indicator light turns o when

welding can be resumed.

4.2 CONTROL CABLE CONNECTOR FUSE

The back panel of the power source has a fuse that protects the control cable connector. Using

an incorrect type of fuse will damage the power source. Therefore, it is important that you

always use the correct fuse type. The type and size of the fuse are indicated next to the fuse

socket.

4.3 ELECTRIC NETWORK OVERVOLTAGE OR UNDERVOLTAGE

If the power source is used in an electric network with insucient voltage (less than 300 V),

the control features of the device are automatically disabled.

The primary circuits of the power source are protected against power spikes. The product’s

mains voltage range is broad enough to prevent over-voltage problems at up to 440 V. Make

sure that the voltage remains within the allowed range, especially if the operating power is

supplied by a generator set. For information on the allowable voltage range, see "Technical

specications" in this guide.

4.4 MISSING PHASE IN THE ELECTRIC NETWORK

If a phase is missing from the mains current, the welding features will be adversely aected or

the machine may have problems starting. Loss of a phase can be caused by a:

• Blown mains fuse

• Damaged mains cable

• Poor mains cable connection in the machine’s terminal block or mains socket

4.5 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: Power source overvoltage

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

continuous overvoltage dangerous to the machine in the electric network. Check the quality

of the supply network.
