7 MAINTENANCE
Note!
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 (authorised
personnel) may remove the safety plates to connect or carry out service,
maintenance or repair work on welding equipment.
Cleaning
Check regularly that the power source is free from dirt.
How often, and to what extent, cleaning should be carried out depends on the
welding process, ar c t ime, disposition and the surr ounding environment. It will
normally suffice to blow the power source clean using compressed air (reduced
pressure) once a year.
If the power source is very dirty, brushing and vacuuming are recommended.
S Disconnect the welding power source from the mains current supply.
S Remove the adapter from the socket. Lock the socket to prevent unauthorised
connection.
At fixed installations, the safety switch should be set to the off position. Lock
the switch.
S Remove the power source’s safety plates for best access.
After cleaning, all safety plates must be m ounted before you connect the power
source to the mains supply.
