5. Instructions
5.1 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.
5.2 Electrical Connection

Put the on-off switch in the 0-position (off) and connect the device to a 220-
240 V~, 50 Hz power supply. The soldering station is now ready for use.
5.3 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 °C and 450 °C.
5.4 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 soldering alloys used in the electronics industry consist of 60 %
tin and 40 % lead. The operating temperature of this type of solder is detailed
below and can vary from manufacturer to manufacturer. However, to meet RoHS
requirements, these solders are no longer allowed and are replaced by lead-free
solders that require a working temperature, which is ± 30 °C (54 °F) higher.
leaded solder lead-free
melting point 215 °C (419 °F) 220 °C (428 °F)
normal operation 270-320 °C (518-608 °F) 300-360 °C (572-680 °F)
production line operation 320-380 °C (608-716 °F) 360-410 °C (680-770 °F)

The included soldering tip consists of copper-plated iron. Used correctly, the
soldering tip has a long durability. Clean the tip immediately before use by rubbing
it on the moist sponge. By doing so residues of unevaporated solder, oxides or other
impurities will be removed.

Before you put the soldering iron back into the holder, you should clean it again and
