Service and Maintenance
GLC 353/503/553 MC3
Monthly checks
1.
Please check the cooling fluid for cleanliness.
2.
Please check the cooling radiator at the rear of the machine for cleanliness.
Quarterly checks
The water cooling pump is provided with a filter which must be checked and, if necessary, cleaned
after 250 working hours. To do this, the welding machine must be switched off and opened and
the filteron the pump removed. The filter is located at the bottom of the pump body below a cap
nut. It should be cleaned using running water, otherwise the welding torch may be damaged due
to overheating !
Bi-annual checks
1.
Please check the interior of the machine and the components for dust and dirt.
2.
Please check the mains cable and welding cable for a firm seat and good contact.
3.
Please ensure that the machine is always correctly connected to earth (grounded).
4.
Please check that the machine cover is correctly assembled and fits tightly.
5.
Please check the cooling radiator for bent laminas and re-aligh, if necessary.

Special instructions
W2.1
Dust and dirt
W2.1.1
The cooling efficiency of the radiator, item 88 at the rear, largely depends on
the cleanliness of the laminas. These have to be cleaned at regular intervals.
It is recommended that cleaning is carried out by blowing dry, oil-free
compressed air through the radiator. This will remove any dust and the radiator
will regain its original cooling efficiency.
W2.1.2
Dust and dirt on the main transformer, rectifier, etc. affect the cooling efficiency
of the fan. Metal dust on the main transformer may also lead to insulation
problems and cause earth or winding short circuits. Depending on the degree of
contamination these parts must be vacuum cleaned, .
We advise you not to use compressed air because this would increase the dust
penetration into the components!
A vacuum cleaner can also be used to clean the upper wiring area. As this area
is sealed, this work is only required at relatively long intervals.
W2.2
Cooling agent, anti-freeze agent, disposal
The coolant must be drained off if it is
contaminated
(it usually becomes a brownish color).
When it must be
disposed of
, in accordance to State or local codes.
-
It must not enter the main drainage system. -
