The utilization 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 trouble-freest 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 cable and power cord 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 power cords must be repaired and installed only by electrical contractors and
installers authorized to perform such operations.
5.2
Power source
Before cleaning the interior of the machine, you need to remove the case by unscrewing the
mounting screws at the top and sides of the machine.
*NOTE To prevent damage, wait approximately two minutes after disconnecting the mains cable
before removing the machine’s case. Perform the following cleaning and maintenance at least
every six months:
1. Clean the interior of the machine and the fan grill’s net of any dust and stains – for example,
with a soft brush and vacuum cleaner.
• Do not use pressured 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 oxidized connections, and
tighten the loosened ones.
• Check for the right tension before you start repairing the connections.
*NOTE Remember that the machine must be repaired only by an electrical contractor or
installer authorized to perform such operations.
5.3 Regular maintenance
Authorized service agents perform regular maintenance by agreement. Tasks included in regular
maintenance:
• Cleaning of equipment.
• Inspection and maintenance of the welding gun.
• Checking of connectors, switches, and control knobs.
• Checking of electrical connections.
• Checking of the mains cable and plug.
• Replacement of damaged or worn parts.
• Calibration testing, with adjustment of the functions and operational values of the
machine, if necessary.
