General remarks
Under normal operating conditions the cooling unit requires only a minimum of care and
maintenance. However, it is indispensable to follow some important points to ensure the
operationality of the welding machine for many years.

(4)
Read operating instructions
The relevant maintenance intervals and
work are described in detail in the following
pages.
Every start-up
-
Check welding torch, interconnection cable assembly and bondings for damage
-
Check whether the allround distance of 0.5 m (1.6 ft.) is kept to ensure that the cooling
air can easily flow and escape.
WARNING!
An electric shock can be fatal. Before opening up the machine,
switch it off, unplug it from the mains and put up a clearly legible and easy-to-un-
derstand warning sign to stop anybody inadvertently switching the machine back
on again. The casing screws are a suitable protective conductor connection for
grounding the casing. The screws must not be replaced by other screws without
reliable protective conductor connection.
CAUTION!
Danger of scalding from hot coolant fluid. Do not inspect the coolant
connection points until the coolant has been allowed to cool.
IMPORTANT!
The coolant must not be disposed of via the sewerage!
NOTE!
For refilling the cooling unit only use coolant of the manufacturer.
