Maintenance and repairs
●
Only qualified electricians are permitted to repair the electrical tools.
●
Pull the mains plug out of the socket before starting any maintenance and repair
work.
●
Follow the maintenance instructions and information regarding filter changes.
●
You are only permitted to use original WELLER replacement parts.
Attention! Danger to life and limb exists if the safety regulations are not complied
with.
2. Description
The WELLER WFE 20D soldering fumes extractor is fitted with a powerful,
maintenance free turbine and therefore best suited for continuous industrial
operation. The unit has been designed for fume extraction direct from the soldering
bit and is unsuitable for surface extraction. The digital electronics ensures easy
operation of the functions available. The vacuum generated by the turbine in standard
mode (mode 0) is electronically controlled to always be at 12,000 Pa. In addition to
this, the turbine rotational speed can be manually adjusted over the range 20% -
100% when in mode 1 (rotational speed control mode). A maximum of 2 vacuum
connections (3) are available for connecting up a DN40 hose system. The hose
system can be installed individually using either vacuum connection position (push-
on nipple) for the soldering bits (max. 20). Alternatively there are another 5 direct
vacuum connections available on the unit for soldering bit fume extraction.
The standard 3-stage filter (fine dust filter, particulate air filter and wideband gas
filter) is suitable for use with soldering fumes. If type approved class H13 particulate
air filters are used then the filter set's degree of separation in the delivered state
stands at 99.95%, in accordance with EN 1822 for a particle size of 0.12µm. The data
can only be realised by using original parts. The filter needs to be changed when a
differential pressure reading is displayed on the unit. The system's full range of
functions can be remotely operated or monitored via a standard RS232 interface. An
operating hours indicator and default operating hours setting display expands the
unit's range of functions.

4. 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 soldering bits, a Ø 7.0 mm hole must
be tapped in the required position, the push-on nipple must be screwed into it and
the vacuum hose from the FE soldering bits must then be pushed onto the nipple.
Electrical connection
The nominal voltage must be checked against the details given on the nameplate
prior to commissioning. If the mains voltage is correct, connect the WFE 20D to the
mains supply (9) and switch on the equipment using the mains switch (11). A green
