7 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Only personnel with the appropriate electrical skills (authorised staff) may r em ove
safety plates.
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.
7.1 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
the power source clean with dry compressed air (reduced pressure) once a year.
Clogged or blocked air inlets and outlets otherwise result in overheating.
7.2 Welding torch
Wear parts should be cleaned and replaced at regular intervals in order to achieve
trouble--free welding.
