7 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
CAUTION!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any faults.
Only those persons who have appropriate electrical knowledge (authorized
personnel) may remove the safety plates.
7.1 Inspection and cleaning
Power source
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.
Welding torch
The welding torch’s wear parts should be cleaned and replaced at regular intervals in
order to achieve trouble--free welding.
