If there is too much solder on the soldering tip, it may drip onto or into the device when you remove or replace the soldering iron. Soldering residue may also fall off the dry metal cleaner/wet sponge into the device when you are cleaning. This can cause a short circuit.

• Protect heat-sensitive surfaces with a suitable cover. Never place the soldering station and the soldering iron stand onvaluablefurnitureoroorsoronacarpet/rug.Maintainasufcientdistancefromcombustibleorammable objects (e.g. curtains).

• Ifthereisapieceofprotectiverubber(orothersimilarmaterial)onthesolderingtip,removeitbeforerstuse.This is designed to protect the soldering tip during transport and is not required.

• Ensure that the screw (16) for the soldering tip is securely in place (do not use a tool to tighten the screw!).

• Insert the soldering iron into the soldering iron holder (11).

• Place the dry metal cleaner into the container on the soldering stand. Alternatively, insert the wet sponge after dampening it slightly with water. When using the dry metal cleaner, place the protective cover (12) onto the soldering iron stand. The protec- tive cover holds the metal cleaner in place and prevents solder from splashing onto the sponge. Dampen the wet sponge with water before use. It must not be too wet; squeeze it to remove any excess water before use. Dampen the sponge from time to time to prevent it from drying out. Wash the sponge occasionally in fresh water.

• Insert the soldering iron connector (18) into the corresponding socket (4) on the soldering station. The connector onlytsinoneposition;donotuseanyforcewheninsertingitintothesocket.Tightentheroundcapnutonthe connector (do not use any tools!).

• The soldering station features an ESD socket (3) for use on an ESD workstation. Use a suitable cable to connect the ESD workstation to the socket on the soldering station.

• Use the mains cable to connect the power-in socket (6) to a standard earthed mains socket.36

a) Switching on and off Before switching the soldering station on, check that the soldering iron is connected correctly. Use the on/off switch (1) to turn the soldering station on (“I” = on) or off (“O” = off). The LCD display (9) will turn on when the soldering station switches on. b) Setting the soldering tip temperature

• Therstlineofthedisplay(“SET”)indicatesthetargettemperature,andthebottomline(“TMP”)showsthecurrent temperature measured by the temperature sensor in the soldering iron.

• The status LED (8) above the temperature control dial (7) indicates whether the heating function is activated (the LED turns on when the heating function is activated). Whenthesolderingironisinthesolderingironholder(11),theLEDwillonlyturnonbrieyatoccasional intervals, as only a small amount of energy is required to maintain the temperature. When you solder on large components, the LED will turn on very frequently or for longer intervals, as a large amount of energy is required to heat the soldering iron.

• The indicator (10) on the left-hand side of the display shows the difference between the current and target tempera- ture. More bars indicate a larger difference. This enables you to quickly determine whether the preset temperature (shownontherstlineofthedisplay(“SET”))hasbeenreached.

• The soldering tip temperature can be set between 50 °C and 480 °C using the temperature control dial (7). Alter- natively,youcansetthetemperatureusingthethreecontrolbuttons(2)(brieypressthecorrespondingbutton). By default, the keys are programmed with the following temperature settings (see section 9 for instructions on how to change these settings). Button “1”: 150 °C Button “2”: 270 °C Button “3”: 360 °C Important: Whenyousetaxedsolderingtiptemperature(withpasswordprotection,seesection10b),youcannot change the temperature using the temperature control dial or the control buttons. If you enabled a preset temperature using one of the control buttons and wish to manually change the temperature, turn the temperature control dial (7) slightly in either direction. You can then change the temperature using the temperature control dial (7). If the temperature control dial (7) is in the leftmost position and you wish to decrease the temperature, turn the temperature control dial slightly in a clockwise direction. You can then set the temperature as usual. If the temperature control dial (7) is in the rightmost position and you wish to increase the temperature, turn the temperature control dial slightly in an anticlockwise direction. You can then set the temperature as usual. The temperature control dial (7) is not directly linked to the heating function (as on conventional analogue soldering stations), because the temperature can also be selected using the control buttons.37

Fullyinsertthesolderingironintotheholdersothatitwillnotfalloutbyaccident–reandburnhazard! c) Standby mode The soldering iron automatically switches to standby mode when it is in the soldering iron holder (11) and has not been used for approximately 20 minutes (the soldering iron has a built-in tilt sensor that detects when the soldering iron is not in use). In standby mode, the temperature drops to 200 °C to save energy and to protect the soldering tip. “SET: STB” and “TMP:200” will appear on the display. Warning! If the preset temperature is lower than 200 °C, the soldering station will heat up to 200 °C when it is in standby mode! You can disable standby mode in two ways:

• Brieypressoneofthethreecontrolbuttons(2).Thesolderingstationwillreturntothepresettemperature(press- ing the control button only disables standby mode and does not enable the corresponding temperature).

• Remove the soldering iron from the soldering iron holder (the built-in tilt sensor detects movement and disables standby mode). d) Power saving mode The soldering iron automatically switches to power saving mode when it is in the soldering iron holder (11) and has not been used for approximately 40 minutes (the soldering iron has a built-in tilt sensor that detects when the soldering iron is not in use). “zzZZZz.. RESTART” will appear on the display. To disable power saving mode so that you can use the soldering station again, switch the soldering station off using the on/off switch (1), and then switch it back on.38

9. Loading/saving temperature settings

You can save a preset temperature to each of the three control buttons (2), e.g. for different solder types or for SMD soldering. By default, the control buttons (2) are programmed to the following temperature settings: Button “1”: 150 °C Button “2”: 270 °C Button “3”: 360 °C You can overwrite these settings with your own temperature settings. The temperature settings are retained after the soldering station is switched off. If you enabled a preset temperature using one of the control buttons (2) and wish to manually change the temperature, turn the temperature control dial (7) slightly in either direction. You can then change the temperature using the temperature control dial (7). a) Loading a temperature setting Brieypressthecontrolbuttonforthetemperaturesettingthatyouwanttoload.Thenewtargettemperaturewillbe displayed on the top line. If this is higher than the previous target temperature, the soldering tip will start to heat up (if the temperature is lower, wait until the soldering tip has cooled down to the new temperature). b) Saving a temperature setting

• Use the temperature control dial (7) to set the desired temperature (shown next to “SET” on the top line of the display). If the temperature control dial (7) is in the leftmost position and you wish to decrease the temperature, turn the temperature control dial slightly in a clockwise direction. You can then set the temperature as usual. If the temperature control dial (7) is in the rightmost position and you wish to increase the temperature, turn the temperature control dial slightly in an anticlockwise direction. You can then set the temperature as usual. The temperature control dial (7) is not directly linked to the heating function (as on conventional analogue soldering stations), because the temperature can also be selected using the control buttons.

• Holddownthecontrolbuttonthatyouwanttoassignatemperaturetoandwaituntilthesettemperatureashes three times and stays constant. This indicates that the temperature setting has been saved. Release the control button. Thetemperaturewillashand“PS1”,“PS2”or“PS3”willbedisplayedtotheleftofthetemperature(de- pending on which button you press). This indicates that the soldering station is saving the temperature setting.39

• Programming a xed soldering tip temperature You can use this function when you plan to use the soldering station in a production facility and do not want other users to change the temperature. When the soldering station is switched on, the soldering tip will always heat up to the preset temperature. The temperature cannot be changed using the control buttons (2) or the temperature control dial (7).

• Calibrating the soldering tip temperature The soldering iron was calibrated to the soldering station before the product was shipped. If the soldering iron is replaced (e.g. due to a defect), the soldering tip temperature must be recalibrated. It is also advisable to recalibrate the temperature when using a new/different soldering tip. A temperature measurement device that can measure temperatures of over 360 °C is required to calibrate the soldering tip. For best results and to prevent false measurements, use a surface probe with a small measuring tip.

• After a few seconds the display will revert to the main menu (see screenshot in section 10. a). To exit settings mode, switch the soldering station off using the on/off switch. Write the password down. If you forget the password, you can reset it to “000”, but this requires you to open the soldering station. This must only be done by people who are trained to repair electrical equipment. This procedure is described in section 10. f).44 f) Resetting the password If you forget the password that you set in section 10. e), the front side of the soldering station has to be removed so that you can reset the password. This must only be done by people who are trained to repair electrical equipment. Improper use may dam- age the soldering station and cause a fatal electric shock! If in doubt, ask a technician to reset the password; do not attempt to reset it yourself. Follow the steps below:

• Switch the soldering off using the on/off switch (“O” = off).

• Disconnect the soldering station from the mains voltage (remove the plug from the mains socket). Remove the mains cable from the power-in socket (6) on the soldering station. Leave the soldering iron connected.

• Remove the four screws on the front of the soldering station, and then remove the plastic ring. You can then fold down the front side with the circuit board.

• Onthebackofthecircuitboardyouwillndtwocontacts(seefollowingdiagram).Thesecontactsweremarkedas “X5”whentheseoperatinginstructionswerepublished.However,youshouldalsobeabletondthecontactsby referring to the diagram (the contacts are circled in the diagram):

• Connect these two contacts, e.g. using a jumper/terminal.

• Position the circuit so that it is not in contact with the metal housing.

• Reconnect the soldering station to the mains and switch it on. Do not reach into the soldering station or touch any electrical contacts. Touching contacts that carry a high voltage may cause a fatal electric shock! Always hold the front plate around the edges. Make sure that the circuit board is not in contact with the metal housing of the soldering station.

• “PASSWD. RESET!” will be displayed on the LC display and the password will be reset to the factory default (“000”).45

• Switch off the soldering station and disconnect it from the mains (remove the plug from the mains socket). Then disconnect the mains cable from the power-in socket on the soldering station.

• Disconnect the two contacts.

• Place the front panel back onto the soldering station. Take care not to pinch any cables. Replace the plastic ring in the correct position and screw it in place. Alwaysremembertodisconnectthetwocontactsrst!

• Connect the soldering station to the mains voltage and switch it on.

• The soldering station is now ready for use and the password is reset to the factory default (“000”).

• Select an appropriate temperature for the desired soldering process. The temperature must always be higher than the melting point of the solder. Toensurethatthesoldermeltsquicklyandowssmoothly,thetemperatureofthesolderingstationshouldbeset to at least 50 °C higher than the melting point of the solder. Soldering for excessively long periods may damage many types of components due to prolonged heat ex- posure. It is therefore advisable to select a higher soldering tip temperature to keep the soldering process as short as possible. However, selecting an excessive temperature can also cause problems (e.g. damage components).

• If you need to heat large quantities of solder (e.g. for a large soldering joint or a soldering joint that dissipates heat (such as a cooling plate)), you can set a higher temperature.

• After you set the desired temperature, the soldering tip will take a few seconds to heat up and reach the target temperature.

• Remove the soldering iron from the soldering iron holder (11). Always use the plastic grips to hold the soldering iron. Never touch the hot tip or the metal shaft, as this may cause burns/injury!

• The solder should melt instantly upon contact with the soldering tip. If smoke is emitted, this is due to evaporating uxcontainedinsidethesolder.

• For larger soldering joints, increase the temperature to speed up the soldering process. Only use the highest temperature setting for as long as necessary to avoid overloading the soldering tip.

• Reduce the temperature of the soldering iron during breaks. This saves energy and prolongs the lifespan of the soldering tip. The soldering station automatically switches to standby mode after 20 minutes of inactivity (see sec- tion 8. C) and to power saving mode after 40 minutes of inactivity (see section 8. d).

• Always place the soldering iron into the soldering iron holder (11) when it is heating up and cooling down and when you are not soldering.

Make sure that the soldering tip is well coated with tin when taking breaks or before switching the soldering station off.

• Ensure that the soldering contacts on the workpiece are clean. Only use solder designed for electronic work. Acidic solder may damage the soldering tip or the work piece.46

• Heat the soldering joint with soldering tip and apply the solder. Remove the solder from the soldering joint, and then remove the soldering tip. Complete the soldering process quickly to avoid damaging the work piece (e.g. dislocated conductors or overheating components).

• Allow the soldering joint to cool down. Depending on the size of the soldering joint, it may take 1–2 seconds for the solder to harden. Do not move the soldered component or cable during this time, as this may result in a so-called “cold soldering joint”. This is a soldering joint with a dull silver look that does not provide a good electrical contact or mechanical joint. A correctly soldered joint should shine in a similar way to chrome.

• Cleanthesolderingtipoccasionallytoremoveuxresidues(usethedrymetalcleaneroradampsponge).Todo this,brieywipethesolderingtipusingthecleanerorsponge. Do not press the soldering tip into the sponge or hold the soldering tip on the sponge for too long, as this may damage the sponge. It would also cause the soldering station to adjust the heating power. Ensurethatthespongeissufcientlydamp.Nevercleanthesolderingtipwithadrysponge! You can also use the dry metal cleaner provided instead of the sponge. Mechanical damage to the soldering tip destroys the protective coating and reduces its lifespan. Do not clean the soldering tip with sharp objects or a metal brush.

• Whenyouhavenishedsoldering,cleanthesolderingtiptoremoveuxresidues(seeabove),andthencoatthe soldering tip with tin. Apply a small amount of tin to the soldering tip, ensuring that the tin forms an even layer on the tip. This prevents corrosion on the soldering tip. Place the soldering iron into the soldering iron holder (11). Switch off the soldering station (“O” = OFF). It takes 10–15 minutes for the soldering iron to cool down completely. Do not touch the soldering tip or holder during this time – burn hazard! Topreventtheriskofare,allowthesolderingstationtocooldowncompletelybeforestoringit.47

12. Changing the soldering tip

Depending on the soldering work you wish to complete, you may need to change the soldering tip (a number of solder- ing tips are available to order as accessories). Compatible accessories can be purchased at www.conrad.com on the corresponding product page (enter the soldering station item number in the search box). Only use soldering tips that are recommended for use with the soldering station. Using other soldering tips may result in false temperature measurements (i.e. the actual temperature of the soldering tip is different to the temperature shown on the display) and damage the heating element, which will void the warranty/guarantee! Useaverynesolderingtipwhenworkingwithsmallcomponentsandawider/attertipforlargercomponents.A larger soldering tip can transfer more heat, which speeds up the soldering process. The soldering tip is subjected to a mechanical and thermal load during use. Over time, the soldering tip will becomeblunt(especiallywithverynesolderingtips),meaningthatyouwillnotbeabletosolderprecisely on small components. The lifespan of the soldering tip depends on several factors. For example, high soldering temperatures signicantlyreducethelifespan. Follow the steps below to replace the soldering tip:

• Turn off the soldering station and let the soldering iron cool down completely.

• Loosen and remove the cap nut (16) on the metal shaft of the soldering iron. The heating/cooling process may cause the cap nut to become very tight. If so, loosen the cap nut (16) with a pair of pliers. However, do not use any force, as this may damage the heating element and void the warranty/guarantee!

• Remove the soldering tip from the heating element.

• Insert a new soldering tip onto the heating element.

• Replace the cap nut and tighten it with your hand. Do not use any force!

• If you have a suitable temperature measurement device, calibrate the soldering tip temperature (see section 10. d).48

13. Replacing the fuse

The fuse protects the device against overload. The fuse should not be triggered during normal use. The fuse may be triggered by a fault in the soldering iron or a short circuit in the cable between the soldering iron and the soldering station. The fuse may also be triggered by a fault in the soldering station. Follow the steps below to replace a defective fuse:

• Switch off the soldering station. If the soldering iron is still hot, allow it to cool down completely.

• Disconnect the soldering station from the mains voltage (remove the plug from the mains socket). Then disconnect the mains cable from the soldering station.

• Removethefuseholder(5)belowthepower-insocket(6).Thiscanbecarefullyprisedoutofplacewithaat screwdriver.

• Remove the fuse from the fuse holder.

• Check the fuse, e.g. with an appropriate meter (digital multimeter). If the fuse is defective, replace it with a new fuse of the same type (see “Technical data” at the end of these operat- ing instructions). Neveruseafusewithotherspecications.Neverbridgeadefectivefuse! Thisconstitutesarehazard!

• Insert the new fuse into the fuse holder. Insert the fuse holder back into the soldering station until it clicks into place.

• Connect the soldering station to the mains and switch it back on. If the fuse blows again, disconnect the soldering station from the mains and ask a technician to conduct a comprehensive check.49

14. Maintenance and cleaning

• The soldering station is maintenance-free, except for the occasional replacement of the soldering tip, sponge and fuse. Servicing and repair work must be done by a technician.

• Before cleaning the soldering station, disconnect it from the mains and remove the mains plug from the mains socket.

• Allow the soldering iron and soldering station to cool down completely.

• Use a clean, soft and dry cloth to clean the exterior of the soldering station.

• Never use aggressive detergents or other chemical solutions, as these may damage the housing (discolourations) or cause the product to malfunction.

• Thesolderingtipdoesnotrequireanyspecialcleaning.Itissufcienttocleanitoccasionallybyusingthewet spongeordrymetalcleanertoremoveuxresiduesandexcessivesolder.

• The soldering tip must be coated with tin before the soldering station is switched off. This prevents corrosion on the soldering tip and prolongs its lifespan.

Electronic devices are recyclable waste and must not be placed in household waste. At the end of its service life, dispose of the product according to the relevant statutory regulations.50

• Is the soldering station connected to the mains and switched on?

• Has the fuse blown? The error message “H-E” is displayed

• The soldering station has detected an internal error in the heating electronics (“H-E” = heater error). Switch the soldering station off, and then switch it back on.

• Is the soldering iron connected to the soldering station correctly?

• The soldering iron may be faulty (cable, heating element or temperature sensor). The error message “SE” is displayed

• The soldering station has detected a problem with the soldering iron

• The soldering iron may be faulty (cable or temperature sensor). It takes a long time for the tempera- ture to drop when you decrease the temperature.

• This is normal and does not indicate a fault. The heating element and soldering tip take a while to cool down to the lower temperature setting. The solder is not liquid. • The temperature is too low.

• The heat from the soldering iron is dissipated too quickly (e.g. when using larger work pieces). Set a higher temperature or use a soldering tipwithalarger/attertip.

• The soldering iron is not suitable (e.g. when soldering gutters).

• The soldering station is only designed for use with soft solders. The preset temperature is not correct

• When you use a measurement device to check the temperature of the soldering tip, the measured temperature may differ slightly from the preset temperature (the temperature sensor measures the tempera- ture in the heating element; the measurement device measures the temperature on the outside of the soldering tip).

• Calibrate the temperature in the settings menu. The temperature cannot be set using the control buttons or the temperature control dial
