1. Description

1. Electronic temperature adjustment, continuously variable from 150°C - 450°C or
with encoder models, fixed temperatures are obtained using encoder plugs.
2. Antistatic soldering iron LR-21 (24V/50W).
3. High performance heating element. (Insulation) 500V.
4. Selection of 22 WELLER "Longlife" Soldering tips.
5. Temperature resistant silicon cord.
6. Visible regulation control.
7. Socket for potential equalisation.
8. Potentiometer locking
9. Mains switch
10. Mains fuse T 0.315A (5x20)
11. 5-channel plug, interlocking
12. Safety support rack, can be free-standing or connected either to the left or right
side of the control unit
13. Cleaning sponge
14. Holder for additional tips.
The soldering Station WECP-20 is best suited for soldering electrically or thermally
sensitive electronic components. A large variety of soldering tools can be connected
via the 6-channel connection socket. The available soldering tools are given in the
accessories list. All soldering tools are electrically isolated from mains and operate
with a protective low voltage of 24V AC.
Analogue temperature regulation is carried out using a potentiometer which can be
used to set the temperature continuously in a range of 50°C to 450°C. A green LED
indicates the status of the regulation.
The mains fuse is easy to change. The fuse can be removed by lightly pushing in the
fuse holder and turning it to the left. Potential equalisation of the soldering tip can be
achieved using the corresponding connection socket on the front side of the unit.
Through the antistatic design of the control unit and irons, the Soldering Station WECP-
20 antistatic fulfils all requirements of the EGB safety regulations.
The soldering station WECP-20 is also available in encoder versions and can be converted
to a COD (encoder) version with a conversion kit.

The soldering iron LR 21* comes standard with a temperature resistant silicon cord
GB
and a "WELLER Longlife" soldering tip type ET-B. The lifetime of the "WELLER Longlife"
soldering tip is lengthened substantially by the electro-plated 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.
* Information contained in the Operation Manuals of any other connected WELLER
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 (13). Place the soldering iron
into the safety support rack (12). Insert the soldering iron plug (11) into the 6-channel
connection socket of the control unit and lock it. Connect the control unit to mains. Be
sure to check for the correct voltage.
Set the desired temperature using the potentiometer (1) and switch on the unit at the
mains switch (9). With COD versions, use the corresponding coded plug to set the
temperature.
The green LED illuminates (6). This LED indicates the status of the regulation.
"Continuous illumination" indicates that the actual temperature lies below the set
temperature. The system is heating.
"Blinking" indicates that the actual temperature corresponds to the set temperature.
