1. Description
The soldering Station WTCP-S is best suited for soldering electrically or thermally
sensitive electronic components. Temperature regulation is carried out using the
WELLER Magnastat principle.
The permanent magnet is attracted to the ferromagnetic temperature sensor when the
tip is cold. This causes the switch to switch on. As the sensor approaches the Curie-
point, it loses its ferromagnetic properties and can no longer hold the permanent magnet.
The magnet releases causing the switch to switch off, thereby interrupting the feed to
the heating element. When the tip cools, the temperature sensor attracts the perma-
nent magnet again and restores the current feed. There is little deviation between diffe-
rent temperature sensors (Magnestats) and they are not subject to wear due to ageing
or material fatigue. An addition feature of this arrangement is that the soldering iron is
switched off when changing tips. The heating element cannot burn out from use without
a soldering tip.
Picture: Weller Magnastat system, see page 55
Selection of the correct working temperature is carried out by simply selecting the
temperature coded soldering tip. The WELLER "Longlife" soldering tips are available in
the temperatures 260°C, 310°C, 370°C, 400°C and 480°C. The lifetime of the WELLER
"Longlife" soldering tip is lengthened substantially by the electroplated finish on the
copper core. There are 21 different soldering tip forms to choose from. You can choose
the optimal tip from one of these.
The Magnastat soldering iron TCP-S* is electrically isolated from mains and operates
with a protective low voltage of 24V AC or DC. The soldering iron comes standard with
a temperature resistant silicon cord and a WELLER "Longlife" PT-B7 soldering tip.
Potential equalisation of the soldering tip can be achieved using the corresponding
connection socket on the front side of the unit.

tools should be observed in addition to the information contained in this Operation
Manual.

2. Commissioning

Fasten the holder spring with funnel to the foot plate of the soldering iron holder (see
exploded view) and soak the cleaning sponge with water (10). Place the soldering iron
into the safety support rack (9). Insert the soldering iron plug (5) into the 3-channel
connection socket of the control unit and lock it. Connect the control unit to mains. Be
sure to check for the correct voltage. Switch on the unit at the mains switch (8). When
using a tip for the first time, tin the end of the soldering tip with solder. This removes
any layers of oxidation and contaminants from the soldering tip.

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 wired for 0 Ohm. A resistance of 120KOhm can be
achieved by using a potential equalisation adapter (52509999).
As a practical supplement for building up a ESD work place, we recommend the push
button adapter (52609699).

4. Working recommendations

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.
