• Because the soldering station heats up during use, it is of paramount importance that you use it only on a stable,
solid and fireproof surface. Never block or cover up the ventilation slots.
• Always power off and disconnect the device from the mains before cleaning it. Use a slightly moist cloth (don't use
any strong cleaning agents, cleaning sprays or solvents). Make sure that while cleaning no liquid can enter the
ventilation slots and the interior of the device.
• Incorrect use of this tool may cause fire.
• Be cautious when using this tool in places where inflammable products are stored.
• Heat can cause fire to inflammable products even when they are not in sight.
• Do not use the tool in an explosive atmosphere.
• Place the tool back in its stand in order to let it cool down before storage.
3. Instructions
a. Preparation
• Put the soldering iron holder in the corresponding hole in the casing of the soldering station.
• Make sure the sponge is completely saturated with clean water and let it drip off before you put it in the sponge
tray.
• Put the soldering tip into the shaft and attach it to the soldering iron with a coupling nut. Only change a soldering
tip when the soldering iron has cooled down. Loosen the coupling nut and gently pull out the soldering tip. Check
the screw fitting regularly and tighten it when necessary.
Warning: Never use the soldering iron without the soldering tip.
b. Electrical Connection
Put the ON/OFF switch in the 0-position (OFF) and connect the device to a 230V/50Hz power supply. The soldering
station is now ready for use.
c. Temperature setting
Switch on the soldering station by putting the ON/OFF switch in the 1-position (ON) (the red switch will light). You
can set the temperature between 150° and 450° C.
d. Operation
Prerequisite for clean joints is the use of suited solder and a correct use of the soldering station. We recommend the
use of solder with a resin flux core. Halogen containing solder should not be used in any case. Before the first uses,
you should tin the new soldering tip. Switch on the soldering station and apply some solder to the soldering tip at a
temperature of 200°C. Perfect joints are only possible at the right soldering temperature. When the soldering
temperature is too low, the solder will not melt enough causing unclean (cold) soldering points. At too high
temperatures, the solder will burn and the tin-solder will not flow. Moreover there is the danger of damaging the PCB
or the components. Only when the temperature of the soldering tip is perfectly adapted to the solder will you have
clean joints. The most common solder consists of an alloy of 60% tin and 40% lead. Below you can find the melting
temperatures for this kind of solder. There may be some discrepancies depending on the manufacturer.
Melting point: 215°C
Normal use: 270°C – 300°C
Desoldering small soldering joints: 315°C
Desoldering large soldering joints: 400°C
