SECTION 9:
ROUTINE MAINTENANCE
The only routine maintenance required for the power supply is a thorough cleaning and inspection, with the
frequency depending on the usage and the operating environment.
The unit should be wiped clean as necessary with solvents that are recommended for cleaning electrical
apparatus. Turn Power Switch to OFF before proceeding. Internal cleaning of the unit should be done every 6
months by an authorized Cigweld Service Center to remove any accumulated dirt and dust. This may need to
be done more frequently under exceptionally dirty conditions.
CAUTION
Do not blow air into the power supply during cleaning. Blowing air into the unit can cause metal
particles to interfere with sensitive electrical components and cause damage to the unit.
