Thank you for placing your trust in our company by pur-
chasing the WELLER WFE 20D soldering fumes extractor.
Production was based on stringent quality requirements
which guarantee the perfect operation of the device. 

1. Caution!

Please read these Operating Instructions and the attached
safety information carefully prior to initial operation. Failure
to observe the safety regulations results in a risk to life and
limb.

The manufacturer shall not be liable for damage resulting
from misuse of the machine or unauthorised alterations.

The WELLER WFE 20D soldering fumes extractor corre-
sponds to the EC Declaration of Conformity in accordance
with the basic safety requirements of Directives
2004/108/EC and 2006/95/EC + 2004/42/EC.

2. Description

The WELLER Soldering Fume Extraction Device WFE 20D has
a powerful maintenance-free turbine, making is perfectly
suited to continuous operation in industry. The unit was
designed for direct extraction at the soldering iron and is
suitable for surface extraction. 

A digital electronics system allows simple and convenient
operation of the available functions. The vacuum created by
the turbine is controlled in standard mode (

mode 0

) elec-

tronically to the preset value of 8.000 Pa. This value can be
changed individually in 

mode 2.

If low extraction power is sufficient, the control setpoint can 
be reduced in 

mode 2.

If mode 2 has been set, the unit must

be switched over to the desired operating mode to prevent
an inadvertent change of the setpoint value. In addition, the
turbine speed can be changed manually in speed-controlled

mode 1 

in the range 20% - 100%. 

For connection to the pipe system DN40, a max. of 2 vacu-
um connections (3) are available. The pipe system can be
arranged individually by positioning the vacuum connections
(plug-in nipples) for the soldering irons (max. 20) as
required. Alternatively, 5 vacuum connections are provided
directly on the unit for soldering iron fume extraction. 

The standard composition of the installed 3-stage filter (fine
dust filter, HEPA filter and wide-band gas filter) is specially
adapted to soldering fumes. With the use of the type-tested
HEPA filters in Class H13, the separation rate of the filter set
upon delivery is 99.95% as per EN 1822 with a particle size
of 0.12 m. These figures are only achieved with the use of
original parts. A required filter change is indicated by a dis-
play of a differential pressure measurement on the unit.
Using a standard RS232 interface, all of the unit's functions
can be operated and remotely controlled. An operating hours
code and operating hours specification widen the scope of
the unit's functions.

3. Commissioning

Direct interconnection of the FE soldering bits

The WELLER WFE 20D soldering fume extractor is fitted out
for the direct interconnection of a maximum of 5 WELLER FE
soldering bits. To connect up the vacuum hose, first remove
the sealing lid and then push the hose directly onto the push-
on nipple (4). The FE soldering bit unit uses a vacuum hose
that is 2.5 m long. If the soldering stations are further away
(up to 5 m), a DN17 extension hose can be used (this can be
obtained as an accessory). Push-on nipples must be fitted to
the end of the DN17 hose and the unit.

Indirect interconnection via a DN40 hose system 
(accessory)

The WELLER WFE 20D is interconnected to the vacuum hose
system via a flexible fume extraction hose NW44 for indirect
operation. In this case the 5 push-on nipples (4) remain
sealed and the sealing plug (3) for the hose system has to be
removed. In order to connect up the hose system for the FE
