NOTE!
Regular maintenance is important for safe and reliable operation.
Only persons with the appropriate electrical knowledge (authorised personnel) may remove
the safety plates to connect or carry out service, maintenance or repair work on the welding
equipment.
For information about the cooling unit see the instruction manual for the cooling unit.
CAUTION!
All warranty undertakings from the supplier cease to apply if the customer
attempts any work to rectify any faults in the product during the warranty period.
6.1
Inspection and cleaning
Check regularly that the power source is free from dirt.
The power source should be regularly blown clean using dry compressed air at reduced
pressure. More frequently in dirty environments.
Otherwise the air inlet/outlet may become blocked and cause overheating. To avoid this, the
air filter should be regularly cleaned. The filter is built of a large and a small mesh. Make sure
that the large mesh is mounted to the upmost part of the power source and the small mesh to
the innermost part of the power source.
Replacing and cleaning the dust filter:
1. Release the dust filter according to the figure.
2. Blow the filter clean with compressed air (reduced pressure).
3. Ensure that the filter with the finest mesh is placed towards the grill.
4. Reinstall the filter.
6.2
Welding torch
Wear parts should be cleaned and replaced at regular intervals in order to achieve
trouble-free welding.
