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
equipment failure.
Disconnect the power source from the mains before handling electrical cables.
If the welding equipment is left unused for a longer period, disconnect the mains plug from the mains.
Do not use the mains plug as a power ON/OFF switch.
Always check before use that interconnecting cable, shielding gas hose, earth return cable/clamp and mains cable are
in serviceable condition. Ensure that the connectors are correctly fastened. Loose connectors can impair welding per-
formance and damage connectors.
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 dis-
charging the capacitor.
Check the electric connectors of the unit at least every six months. Clean oxidized parts and tighten loose con-
nectors.
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.
