4. MAINTENANCE
the amount of use and the working environment should be taken into consideration when plan-
ning the frequency of maintenance of the machine. Careful use and preventive maintenance will
help to ensure trouble-free operation.
4.1. CABLES
Check the condition of welding and connection cables daily. Do not use faulty cables! Make sure
that the mains connection cables in use are safe and according to laid down regulations.
The repair of the mains connection cables must be carried out only by an authorised electrician.
4.2. POWER SOURCE
Note! Isolate the plug of the machine from the mains socket and wait approx. 2 minutes
(capacitor charging) before removing the casing plate.
Check at least every half year:
- Electric connections of the machine - clean the oxidized parts and tighten the loosened ones.
Note! You must know correct tension torques before starting the reparation of the joints.
- Clean the inner parts of the machine from dust and dirt e.g. with a soft brush and vacuum-
cleaner. Do not use compressed air, there is a risk that dirt is packed even more tightly into
gaps of cooling profiles!
Only authorised electrician must carry out repairs to the machines.
