1. Description

The soldering Station WTCP 51 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 permanent magnet again and restores the current feed. There is little deviation
between different 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 43
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, 425°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 22 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.

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. Place the soldering iron into
the safety support rack. Insert the soldering iron plug into the 3-channel connection
socket (2) of the control unit and lock it. Connect the control unit to mains (3). Be sure
to check for the correct voltage. Switch on the unit at the mains switch (1). 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

The soldering tip is connected directly to the mains earth via the electrical cable (hard
earthing).

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.
Do not immediately run the heating element along iron or expose it to an alternating
electrical field. This can influence the regulation system.
When soldering and desoldering, take into consideration the soldering instructions of
the components, particularly their temperature limits.
