10 ROUTINE MAINTENANCE & INSPECTION
The only routine maintenance required for the PEGAS range of machines is a
thorough cleaning and inspection, with the frequency depending on the usage
and the operating environment.
WARNING
Disconnect the PEGAS from the mains supply voltage before
disassembling.
Special maintenance is not necessary for the control unit parts in the Welder. If
these parts are damaged for any reason, replacement is recommended.
CAUTION
Do not blow air into the welder during cleaning. Blowing air into
the welder can cause metal particles to interfere with sensitive electronic
components and cause damage to the welder.
To clean the welder, disconnect it from the mains supply voltage then open the
enclosure and use a vacuum cleaner to remove any accumulated dirt and dust.
The welder should also be wiped clean. If necessary, solvents that are
recommended for cleaning electrical apparatus may be used.
Troubleshooting and repairing of PEGAS welding equipment should only be
carried out only by suitably qualified or competent person.
