6 MAINTENANCE
NOTE!
Regular maintenance is important for safe and reliable operation.
Only those persons who have appropriate electrical knowledge (authorised personnel) may
remove the safety plates to connect or carry out service, maintenance or repair work on
welding equipment.
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 Power unit
Check regularly that the welding power source is not clogged with dirt.
How often and which cleaning methods apply depend on: the welding process, arc times,
placement, and the surrounding environment. It is normally sufficient to blow down the power
source with dry compressed air (reduced pressure) once a year.
Clogged or blocked air inlets and outlets otherwise result in overheating.
Replacing and cleaning the dust filter
• Release the dust filter according to the figure.
• Blow the filter clean with compressed air (reduced pressure).
• Ensure that the filter with the finest mesh is placed towards the grille.
• Reinstall the filter.
6.2 Welding torch
Wear parts should be cleaned and replaced at regular intervals in order to achieve
trouble-free welding.
