6. Maintenance
The utilisation level of the power source and its working environment should be taken into
consideration in planning the frequency of maintenance of the machine. Appropriate use and
preventive maintenance guarantee the best trouble-free use of the equipment. This allows you to avoid
interruptions in use and increases the productivity of the machine.
5.1 Cables
Check the condition of welding and mains cables daily. Do not use damaged cables. Also make sure that
all extension cables used in the mains connection are in proper condition and compliant with
regulations.
NOTE! The mains cables may be repaired and installed only by electrical contractors and
installers authorised to perform such operations.
5.2 Power source
Make sure the machine is placed away fromany grinding area.
1.
Clean the exterior of the machine and the fan grills net of any dust and stains – for
example, with a soft brush and vacuum cleaner.
•
Do not use pressurised air. The stain may become compressed into the grooves of the coolers.
•
Do not use a pressure-washing device.
2.
Check the electrical connections of the machine. Clean any oxidised connections, and tighten the
loosened ones.
•
Check for the right tension before you start repairing the connections.
NOTE! Remember that the machine may be repaired only by an electrical contractor or installer
authorised to perform such operations.
