5.2 Care and cleaning
The stud welding system does not require any special care.
The following cleaning work is nevertheless recommended.
The cleaning intervals depend on the degree of soiling, but
should not exceed max. six months.
Warning: The power unit must be switched off and
disconnected from the mains power supply before cleaning.
Welding gun
• It must be ensured that the handle of the welding gun is
always dry, clean and free of greases and oils.
Caution: No aggressive agents, agents containing alcohol or
in- flammable liquids may be used to clean the welding system.
• Positioning feet and chucks soiled with weld spatter
must be cleaned with a brass wire brush.
Power unit
• The housing must be wiped with a damp cloth. The
rating plate
and safety information must be kept in a legible condition.
Caution: No aggressive agents, agents containing alcohol or
in- flammable liquids may be used to clean the welding system.
• The front panel of the power unit must be cleaned with a
grease dissolving cleaning agent. The LED indicators
must be clearly readable in operation.
Connecting cables
• All connecting cables must be cleaned with a dry cloth.
Scorched sites or mechanical defects can then be
detected more easily. The cables must be replaced if
necessary.
Inside the device
• It might also be necessary to clean the inside of the
device if it is very dirty.
Warning: Only authorised electricians may open the power
unit
and work inside the housing.
The power unit must be switched off, disconnected from the
mains power supply and secured so that it cannot be switched
on again before opening.
• Dirt and contamination inside the power unit like metallic
dust or conductive chips must be sucked off. They may
not be blown out with compressed air!
Warning: After the cleaning work the device must be restored
to and handed over in orderly condition so that – when used
properly in accordance with these instructions – it does not
pose a danger to the user or the environment.
