9.1 Maintenance and cleaning intervals
The specified intervals are standard values and refer to single-shift operation. We recommend recording the
inspections. The date of the inspection, the detected defects and the name of the inspector must be recorded.
9.2 Cleaning the device
Dirty air inlets and outlets can significantly impair the cooling of the device. Metallic dust can additionally
lead to insulation problems and short circuits in the electronics. Dust accumulation on the fan blade
and cooling elements leads to insufficient heat dissipation. In this case, the <Warning/temperature>
LED illuminates.
Daily
► Check that the device is properly grounded.
► Make sure that there is no abnormal heat generation along the
cables.
► Check the cables are securely connected.
► Check that there are no problems with the insulation between
the cables and the component.
► Check that the cables are not damaged.
► Check that none of the welding power source plastic covers are
damaged.
► Check that there are no metallic noises, abnormal vibrations, or burnt
odors in the device.
► Check that the fan rotates smoothly and evenly and that air is coming
out of the vents on the front and rear of the device.
► Check that the buttons on the control panel function normally.
► Make sure that there are no large fluctuations in the primary power
supply.
No longer than 1,000
operating hours or more
frequently depending on
the location
► Clean the device.
