SECTION 9: ROUTINE MAINTENANCE & INSPECTION
The only routine maintenance required for the Fabricator range of machines is a
thorough cleaning and inspection, with the frequency depending on the usage and the
operating environment.
WARNING
Disconnect the FABRICATOR from the Mains supply voltage before disassembling.
Special maintenance is not necessary for the control unit parts in the Power Source
and
Wirefeeder. If these parts are damaged for any reason, replacement is
recommended.
CAUTION
Do not blow air into the Power Source / Wirefeeder during cleaning. Blowing air into
the Power Source / Wirefeeder can cause metal particles to interfere with sensitive
electronic components and cause damage to the Power Source / Wirefeeder.
To clean the Power Source / Wirefeeder, disconnect it from the mains supply voltage
then open the enclosure and use a vacuum cleaner to remove any accumulated dirt
and dust. The Power Source / Wirefeeder should also be wiped clean. If necessary,
solvents that are recommended for cleaning electrical apparatus may be used.
