Manual 0-2470 43 CUSTOMER/OPERATOR SERVICE
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.
Disconnect primary power to the system before disassembling
the torch, leads, or power supply.
Do not blow air into the power supply during cleaning. Blowing
air into the unit can cause metal particles to interfere with sensi-
tive electrical components and cause damage to the unit.
To clean the unit, open the enclosure (see Service Procedures.
page 62) and use a vacuum cleaner to remove any accumulated
dirt and dust. The unit should also be wiped clean. If necessary,
solvents that are recommended for cleaning electrical apparatus
may be used.
