
Always fasten the nut tightly when attaching the tip. This ensures a good electric
connection. Ventilate the place of work sufficiently in order to take unwanted vapors
quickly away from melting material.
 The mains power supply lead for the soldering gun may only be replaced by a
specialist electrician.
 Use only original accessories which are supplied or recommended by the
manufacturer.

This appliance can be used by children aged from 8 years and above and persons
with reduced physical, sensory or mental capabilities or lack of experience and
knowledge if they have been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved.

Children shall not play with the appliance.
 Cleaning and user maintenance shall not be made by children without supervision
5 OPERATION
5.1 Connection
This soldering gun may only be connected to single phase alternating current. The voltage
of the electric power supply on the network must correspond with the instructions on the
type plate of the machine. Connection to a socket without an earthed contact is also
possible since the double insulation complies with the standard requirements according to
DIN EN60335-1:2002.
5.2 Switching on
CAUTION’ Use this appliance only for work which is included in the
established operative range

Switch-on: press switch 4 and Leave: approx.l000g pressed. Status indicator 3
lights up when the appliance is switched on.
 Switch-off: release switch 4.
 The duration of the current supply determines the heat of the solder (longer current
supply = higher solder temperature). While soldering, do not keep the switch pressed
for too long. Determine the necessary duration for current supply in practice through
control of the temperature of the solder. In order to achieve a constant temperature,
avoid constant current for more than 12 seconds and cutoff current of over48
seconds. As soon as you release the switch, the temperature of the solder is
automatically reduced. A subsequent turning on of the switch ensures a fast increase
in temperature. Constant solder temperature guarantees optimum solder quality,
avoids running the soldering tip at temperatures which are too high and extends the
service life of the appliance.
Below, we give you some examples of poorly soldered joints:

It the soldering tin is tear-shaped, the soldering coagulate was too cold.
 If the soldering tin is dull and slightly porous or crystalline, the parts were probably
moved during the cooling process.
 If too little soldering tin has been left in the joint, the soldering was too warm or the
soldering tin was not melted sufficiently.
 If the soldering tin is yellow or black, this means that too much soldering paste has
been used or that the inner core of the tin solder wire has become overheated during
soldering.
