• Press filter cleaning ON/OFF - RESET button again
(See Figure B.2 item E) to start off-line cleaning.
During the off-line cleaning cycle the entire filter car-
tridge is cleaned systematically by compressed airjets.
This cycle takes approximately one hour.

If desired, the off-line cleaning cycle
can be interrupted by pressing the

ton (See Figure B.2 item E) .
------------------------------------------------------------------------
After the cleaning cycle is finished, system operation
can be continued.
When you continue welding and the control light starts
blinking again immediately or shortly after the cleaning
cycle is finished, the LongLife filter cartridge is saturat-
ed and should be replaced.
• See Filter Replacement.
WARNING
Saturation or clogging of the filter
cartridge results in a decrease of
the extraction capacity which could
result in a reduced extraction of
welding fumes.
Therefore, stop welding immediately when the
machine enters the ALARM phase.
