Caution; Description; Commissioning - Weller WFE Manual De Uso

English
Thank you for placing your trust in our company by purcha-
sing the Weller WFE soldering fume extraction unit.
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 soldering fume extraction unit corresponds
to the EC Declaration of Conformity in accordance with the
basic safety requirements of Directives 2004/108/EC and
2006/95/EC.

2. Description

The Weller WFE soldering fume extraction unit is equipped
with a maintenance-free compressed air converter for vacu-
um generation and is therefore ideally suited to continuous
industrial operation. The compressed air converter is ade-
quately designed to extract the soldering fumes from 2
Weller Fumex-Extraction soldering bits. The vacuum hoses of
the FE soldering bits are connected directly to the WFE sol-
dering fume extraction unit. To operate the WFE cleaned, dry
compressed air (3.5 bar - 6 bar) is required. The compressed
air can be switched off using a control valve on the unit's
compressed air connection.
A built-in lifting device for changing the filters allows trouble-
free replacement of the filter cartridge and preliminary filters
without the aid of tools.
The 3-stage filter installed, comprising fine particulate air fil-
ter F7, Class E12 particulate filter and wide band gas filter
(50% activated carbon; 50% Puratex) is ideally suited in this
configuration to the extraction of soldering fumes. The parti-
culate filter and the gas filter are contained in the main filter
cartridge. Both filter elements are disposable filters and the
fine particulate air filter (preliminary filter) can be changed
several times before the main filter cartridge has to be repla-
ced.
Together with the exhaust air filter (activated carbon), which
absorbs odours caused by compressed air, the WFE is used
as a circulating air unit. It is not necessary to draw off the
exhaust air.

3. Commissioning

Place the FE soldering bit in the safety rest. The WFE-P
soldering fume extraction unit is equipped for the connection
of 2 Weller FE soldering bits (5). On connection of an FE
soldering bit, the vacuum hose is attached to the open
connector nipple. The second connector remains closed.
Only take off the closure cap on connection of a second
vacuum hose.
Insert the compressed air hose, external diameter 6 mm
(PUN-6 x 1) into the compressed air connection (5) of the
WFE as far as it will go.
If the compressed air supply is correct (3.5 - 6 bar, clean
oil-free) connect the WFE to the compressed air supply
system and, if necessary, open the control valve (6).
Maintenance
Before maintenance work is undertaken, the unit must be
switched to its unpressurised state.
In order to guarantee trouble-free operation of the unit, the
vacuum tube and extraction hose of the FE soldering bit must
be cleaned regularly. If heavily soiled, the extraction tube can
be placed in a gas-tight sealed container in cleaning alcohol
(spirit) until the flux residues have dissolved.
Warning: When using cleaning agents, the legal safety
provisions with regard to their handling must be obser-
ved. The cleaning agent must be treated as hazardous
waste and must be disposed of in accordance with the
prevailing local regulations.
