Description; Technical Data; Commissioning - Weller WFE P Operating Instructions Manual

1. Description **

The Weller WFE-P is suitable for the extraction of soldering fumes in conjunction with
WELLER FE soldering bits. The unit is best suited to continuous industrial operation in
the workplace due to its maintenance-free pump drive and low noise generation. The
vacuum hoses of the FE soldering bits are connected directly to the WFE-P soldering
fume extraction unit. A built-in thermal cut-out protects the unit against overload. 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 filter, Class P3 particulate
filter and wide band gas filter (50% activated carbon; 50% Purafil) is ideally suited in
this configuration to the extraction of soldering fumes. The particulate 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 replaced.
Warning: When using extraction equipment, the legal limits with regard to contaminants
in the workplace must be observed and regularly checked by the operator of the
extraction equipment.

2. Commissioning

GB
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.
Before commissioning, check the mains voltage against the information on the type
plate. If the mains voltage is correct, connect the WFE-P to the mains (7) and switch on
the unit at the mains switch.
Maintenance
Before maintenance work is undertaken, the unit must be disconnected from the mains
by pulling out the mains plug.
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 observed. The cleaning agent must be treated as hazardous
waste and must be disposed of in accordance with the prevailing local regulations.
If the extraction performance of a cleaned FE soldering bit is no longer adequate, the
filters must be checked. The preliminary filter can be changed several times before the
main filter has to be replaced.
When original WELLER filters are used in the prescribed manner, the service lives of
the particulate filter and the wide band gas filter are designed to be approximately
equal.
To change the filters, the two release buttons (3) for the lifting device must be pressed
simultaneously. The built-in lifting device lifts up the pump casing (2) and exposes the
main filter cartridge (6). Following this, the main filter cartridge and the preliminary
filter below it can be replaced without the use of tools (see also exploded-view drawing).
