ESAB AIR 140, User Instructions

13

Plug the charger into an appropriate mains supply.  Connect the battery charger plug to the charging
socket of the battery pack, the LED (light emitting diode) indicator will light if the charging circuit is
satisfactory.
Batteries are supplied in a discharged condition, and must initially be charged for 20 hours before
use. Subsequent charges only require 16 hours.
Constant undercharging may impair the battery capacity.
If the turbo unit is to be stored without use for more than 3 months the battery must be detached
from the turbo unit before storage.
(Minimum design duration = 4 hours). Exact duration will depend on a number of factors such as
filter state, motor and battery condition etc. but will typically be around 8 Hrs.

4.2. Pre-Filters
The pre-filter is available as an optional item, which sits in front of the main filter and removes
coarse dust.
Frequent changing of the pre-filter will maximise the life of the main filter (See 4.3 Filter fitting).
The pre-filter should be changed immediately the airflow indicator indicates low flow (See section 5).

4.3.  Main filter
WARNING  This Turbo unit offers NO protection unless a Main filter is fitted.
Care should be taken when handling filters.
Do not touch the pleated paper filter medium.
Do not use filters with damaged paper filter medium.
Do not use filters after their expiry date.
Do not use filters with no or damaged filter seal.
If after changing the pre-filter, the airflow indicator still indicates low flow, the main filter should be
changed as detailed below.
Filters should be fitted as follows. :
Remove the front cover by easing open the right hand side.
Fit the filter squarely into the turbo unit.
Place pre-filter over filter (if used).
Close the cover over the filter by pressing down on the centre of the cover until it snaps home,
taking care that the cover does not touch the filter media when being closed.

FILTERS - IMPORTANT
To  ensure effective maximum protection for the user, main filters must be changed regularly
(Manufacturers recommendation: at most 40 working hours for high dust environments and at most
80 working hours for medium dust environments). Use in conjunction with airflow warning device
and refer to main power unit instructions. Regular changing of filters will also protect and improve
the life of the power unit.

5. AIR FLOW TEST

Air 140:
The turbo unit is designed to exceed the requirements of EN 146 in that it will provide a flow rate of
at least 120 litres/min for at least 4 hours under all conditions when used with the Albatross welding
shield or 140 l/min when used with the Eye-Tech auto-change welding shield, assuming a fully
charged battery at start.

Airflow should always be checked before use or when insufficient airflow is suspected.

The Turbo units airflow is checked with a filter (and pre-filter, if used) fitted, a charged battery pack
and with the unit switched on.
Locate the airflow indicator into the outlet/locking ring of the turbo unit and turn on.  If the indicator
rises so that the line marked B is visible when looking directly from the side, then the unit is providing
sufficient air.

Air 175 AL:
The turbo unit is designed to exceed the requirements of EN 12941 in that it will provide a flow rate
of at least 140 litres/min for at least 4 hours under all conditions, assuming a fully charged battery at
start. (Minimum design duration = 4 hours).
The turbo unit will give an audible and visual alarm when either the clogging of the filter causes the
