11. Repairs
Danger!
Repairs to electric tools must
be carried out by qualified electrici-
ans only!
Welding machines in need of repair can
be sent to the service centre of your
country. Refer to the spare parts list for
the address.
Please attach a description of the fault to
the power tool.
12. Environmental Protection
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.
13. Troubles
The Powerbox is protected against over-
loads with multiple, independent of each
other working protective devices.
These protective devices also comprise
the fine-wire fuses, fitted on the PCBs.
Should any of these fuses blow, it is an
indication of some serious machine fault.
Danger! High voltage!
Never replace a fine-wire fuse
inside the machine on your own.
Contact a qualified electrician!
Before fitting a fresh fuse, the
machine must be completely checked
and the cause for the fault removed!
13.1 Error messages

onds, then ON again.
Error message 444
The control has detected a fault in the water
cooling (to hot, not switched on, faulty):
− Check water cooling unit.
Error message 555
Temperature and/or phase failure.
When the permissible duty cycle or tempera-
ture is exceeded, the machine switches OFF:
− In such case do not switch the
machine off.
The fan can no longer run, which
extents the cooling down time.
Error message 666
Communication error between SDV and Pow-
erbox:
− Check all connections.
18
Error message 775 and 776
No match between SDV and Powerbox. Dif-
ferent revison numbers (software):
− Contact customer service.
Error message 777
No suitable charateristics curve selected:
− Select
a
suitable
curve.
Status message 888
The operating mode PROGRAMM is
selected. Programming of characteristics
curves (optional) possible:
− Select different operating mode.
Note:
If the error can not be corrected:
− Switch the machine OFF for 5 sec-
