Maintenance
The temperature sensor (52641099 Exploded view) is encased in stainless steel. Thishas
a cone-shaped tip for optimal heat contact and has been exactly adjusted for the soldering
tip. This arrangement ensures the best possible temperature transfer. Please be sure that
this opening is not impaired by dirt, foreign bodies or deformation since these will affect the
temperature regulation.
3. Potential equalisation
Potential equalisation of the soldering tip can be achieved using the 4mm metal socket on
the front side of the unit. Building up of a potential-free work place including a good earthing
is recommended, e.g. when soldering highly integrated MOS components.
Potential equalisation is factory set with 0 Ohm impedance. R/C filter 120 KOhm/22nF is
possible by disconnecting a wire jumper on the regulator circuit board (circuit diagram point 7).
As a practical supplement for building up an ESD work place, we recommend the push
button adapter 52609699.

4. Working recommendations
Never use the soldering iron without a tip. Doing so will damage the heating element
and temperature sensor.
Order No.

Always be sure that the soldering tip is properly tinned during pauses in soldering and
when replacing the soldering iron into the holder. Don't use aggressive fluxing agents. Any
mechanical treatment of the soldering tip destroys the electro-plated protective coating of
the soldering tip and decreases its lifetime.
There is a possibility to attach the safety support rack to the control unit. The safety support
rack can be attached to the left or the right side of the control unit and locked by sliding it back.
After setting the temperature with the potentiometer, the knob can be fixed in place by tigh-
tening the screw located below the turn knob underneath the control unit with a screwdriver
(Philips No. 1).
The Soldering Station has been adjusted for a medium soldering tip. Temperature deviations
can occur due to tip changes and by use of other tip forms.
5. Safety notices
The manufacturer assumes no liability for uses other than those specified in the Operation
Manual as well as any self-made changes to the unit.
This Operation Manual and the warning notices therein should be read carefully as well as
kept in good view and near the soldering unit. Failure to observe these warning notices can
lead to accidents, injuries or damage to health.
The WELLER Soldering Station EC 2002 complies with the EC Declaration of Conformity
according to the fundamental safety standards of the directive 89/336/EWG, 73/23/EWG
and 89/392/EWG.
