4. MAINTENANCE
When considering and planning routine maintenance, consider the operating frequency of the welding system and the
working environment.
Correct operation of the welding machine and regular maintenance helps you avoid unnecessary downtime and equip-
ment failure.
Daily maintenance
Maintenance of power source
Follow these maintenance procedures to maintain the proper functioning of the welding system:
• Check that all covers and components are intact.
• Check all the cables and connectors. Do not use them if they are damaged.
For repairs, contact Kemppi at www.kemppi.com or your dealer.
Periodic maintenance
Only an authorized electrician is allowed to carry out electrical work.
Only qualified service personnel is allowed to carry out periodic maintenance.
Before removing the cover plate, disconnect the power source from the mains and wait for about 2 minutes before
discharging the capacitor.
Check the electric connectors of the unit at least every six months. Clean oxidized parts and tighten loose connectors.
Use the correct tension torque when fastening loose parts.
Clean the outside parts of the unit from dust and dirt, for example, with a soft brush and vacuum cleaner. Also clean the
ventilation grill at the back of the unit. Do not use compressed air, there is a risk that the dirt will compact even more
tightly into gaps of cooling profiles.
Do not use pressure washing devices.
