Danger!

Repairs to power tools must be

carried out by qualified electricians

only!

Welding machines in need of repair can

be sent to the service centre of your

country. Refer to spare parts list for

address.

Please attach a description of the fault to

the power tool.

The machine's packaging can be 100 %

recycled.

Worn out power tools and accessories

contain considerable amounts of valua-

ble raw and rubber materials, which can

be recycled.

These instructions are printed on chlo-

rine-free bleached paper.

In case of faults, error messages are dis-

played on the display to help identify the

source of the error.

Simultaneously the Fault LED is perma-

nently lit.

E02

Excess transformer temperature.

− The Excess temperature LED is lit.

− DO NOT switch machine OFF,

in order for the fan to cool the

machine down faster.

− If the temperature has fallen off to

normal levels, the display will show

the welding current again.

You may now continue welding.

E03

The lead to the transformer's tempera-

ture sensor may be broken.

E04

Possible short in the transformer's tem-

perature sensor lead.

E06

The machine's control has detected a

supply voltage of more than 20% below

the rated voltage.

To avoid excess primary currents the

machine shuts down.

Note:

This error message must be

acknowledged.

− Turn the machine OFF for 5 sec-

onds, then ON again.

If the error message appears again, turn

OFF and contact a qualified electrician!
