2. Description

The WTA 50 is a pair of heated tweezers for desoldering SMD
components. The desoldering tweezers can be connected to
all Weller soldering and desoldering stations with an electro-
nic control system. In each of the two movable heating ele-
ments there are temperature sensors which ensure precise
temperature balance on both shanks. The heating elements
each have a 25-watt heating output and are operated using
protective low voltage. ESD-compatible design and a tempe-
rature-resistant connection cable supplement the quality
standard.

4. Potential balance

The heating elements are connected to the control unit via a
potential balance lead. The potential balance can be produ-
ced by following the operating instructions for the control
unit.

5. Operating guidelines

Using the soldering tips, melt on both sides of the component
to be connected and lift off the component. While doing so, do
not exert excessive pressure on the structural element. Set
the tip temperature as low as possible in order to protect the
circuit board and the structural elements.
The operating instructions of the control unit being used are
valid alongside these operating instructions.

6. Maintenance instructions

When replacing tips always use new set screws.
Moisten soldering tips regularly with solder containing flux.
