Weller WTA 50 Betriebsanleitung Seite 6

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 electronic
control system. In each of the two movable heating elements 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 temperature-resistant connection cable supplement the quality standard.
Technical data
Connection voltage : 24V protective low voltage
Power consumption : 2 x 25W
Operating temperature : up to 450°C
Heating-up time : approx. 65 secs.
Inserting and adjusting soldering tips
Insert the soldering tip suited to the soldering application and align. Fasten the tips using the
attachment screws (2). The soldering tip position can be adjusted precisely by loosening the
attachment screw (4). The complete heating element can be turned and shifted axially.
Commissioning
Place desoldering tweezers in the rest. Insert the connector plug into the connection socket
provided for it and lock. Remove all flammable objects from the immediate area around the
soldering tool. Switch on the control unit at the mains switch and set the desired temperature.
After the soldering temperature has been reached, moisten the soldering tip, which can be
moistened selectively, with solder.
Potential balance
The heating elements are connected to the control unit via a potential balance lead. The
potential balance can be produced by following the operating instructions for the control
unit.

Operating guidelines
GB
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.
Maintenance instructions
When replacing tips always use new set screws.
Moisten soldering tips regularly with solder containing flux.
Warning instructions
When not using the desoldering tweezers, always place in the original rest.
Wear suitable working clothes and protect your eyes.
Do not work with live parts.
Avoid unintentional operation.
Observe the safety regulations applicable to your workplace.
Read the warning instructions for the control unit being used.
