4. Features
Soldering/Desoldering Function
Isolated power supply: high-quality 32 Vac transformer designed for lead-free soldering/desoldering.
Temperature stability: the tip temperature is accurate to within ± 3 °C (6 °F).
Vacuum switch: suction is controlled by a finger-actuated thyristor circuit conveniently located on the
desoldering handle.
Heater/sensor fail detection: if the sensor circuit fails, the display reads "S--E" and the heater power is cut.
If the heater circuit fails, the display reads "H--E" and the heater power is cut.
Temperature lock feature: you can lock the temperature with a password for use in a production line.
The “zero voltage” switching design protects voltage and current sensitive components (such as CMOS
devices) against overcurrent and transient voltage spikes.
Delayed suction: to prevent solder from clogging up the tip, the delayed switch allows the pump to continue
sucking for 1.5 seconds after you release the control switch.
Lightweight soldering iron: the ergonomic mini handle stays cool and prevents operator fatigue.
Energy saving mode: when the station has been idle for 20 minutes, the energy saving function
automatically brings down the temperature to 150 °C (302 °F). Activating the soldering/desoldering iron
disengages the power saving feature, and the unit immediately returns to the preset temperature. When
the station has been idle for 40 minutes, the device switches off the power to the irons to lower the power
consumption and extend the tip life.
You can use both soldering and desoldering irons at the same time. To save power, you can switch off the
irons individually.
Hot Air Function
600 W heating element
The adjustable temperature allows for safely removing QFP, SOP, PLCC, SOJ… chips. The static-free circuit
design is safe for sensitive elements such as CMOS ICs.
Sensor/pump fail detection: if the sensor circuit fails, the display reads "S--E" and the heater power is cut.
If the pump circuit fails, the display reads "P--E" and the heater power is cut.
Automatic cooling: after switching off the power, the cooling system starts automatically and brings down
the temperature to 100 °C (212 °F) to protect the heating element from burning.
Heating element auto-protection: protects the heating element from overheating, and extends its life.
5. Operating Temperature
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 that is ± 30 °C (54 °F) higher.

VTSSD4
V. 01 –15/05/2014 5 ©Velleman nv
Leaded solder
Lead-free solder
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)
A good joint is assured if the iron's operating temperature is set within the parameters suitable for the type of
solder being used. The solder will flow too slowly if the temperature is too low; if the temperature is too high,
the flux in the solder may burn which will give rise to billowing white smoke. In turn, this will result in a dry
joint or in permanent damage to the PCB.
Important note: Do not use temperatures higher than 410 °C (770 °F) for normal soldering or desoldering
purposes. You can use the device at higher temperatures for short periods, but this will shorten the lifespan of
the tip.
Desoldering
Recommended tip temperatures for desoldering are detailed below. They can vary from joint to joint.
For a small joint
320–360 °C (608–680 °F)
For a larger joint
370–400 °C (698–752 °F)
If the temperature is too low, the solder will flow too slowly, which may cause clogging in the desoldering tip. If
the temperature is too high, you may burn the PCB.

Important note: Do not use temperatures higher than 410 °C (770 °F) for normal soldering or desoldering
purposes. You can use the device at higher temperatures for short periods, but this will shorten the lifespan of
the tip.
Warning! Do not touch the metal parts of the soldering or desoldering iron while the unit is in use or while it is
cooling down, in order to avoid burns.
1. Switch on the station [1].
1. Soldering: press the UP button ▲[7] until the soldering display [9] indicates 250 °C (or 482 °F).
Note: press and hold the ▲or ▼button to increase setting speed.
2. Wait until the temperature is stable: the heating indication [10]blinks.
3. Tin the surface of both the soldering and desoldering tip by applying a new protective layer of solder.
4. When working with a new tip, let the station idle for three minutes at 250 °C (482 °F).
5. Set the irons to the desired working temperature.
6. Always return the soldering irons to their stand between uses.
Important Desoldering Notes
Do not activate the vacuum pump until the solder has melted completely. Move the hot tip around the lead
to melt it, leaving visibly melted solder on the component side of the PCB.
Release the vacuum switch only when the tip is completely solder-free, otherwise the tip may clog.
Add solder to the joint of the component and allow the solder to melt completely for improved desoldering.
Remove the solder collector and clean it after no more than 200 applications. However, daily cleaning is
strongly recommended, especially if the device is used frequently.
Replace the cotton pad in the solder collector and the in-line filter when they start to turn yellow.
Use the included spring wire to clean the tip in case of insufficient suction. Also, check the in-line filters.
Make sure that all filters are in place during operation in order to avoid damage to the vacuum pump.
See Cleaning and Maintenance when you wish to replace the tip.
9.3 Common Causes of Tip Failure
The temperature of the tip exceeds 410 °C (770 °F).
The tip is not sufficiently tinned, or the tip is not tinned when idle.
Lack of flux in soldering, wicking, repair, and touch-up operations.
Wiping the tip on a surface with a high sulphur content or on a dirty or dry sponge.
Contact with organic or chemical substances such as plastic, resin, silicone, and grease.
Impurities in the solder and/or a low tin content.

VTSSD4
V. 01 –15/05/2014 9 ©Velleman nv
9.4 Tip Maintenance
The soldering uses extremely high temperatures. Make sure that the unit is switched off and has cooled
down for maintenance purposes.
Remove the tip and clean it after heavy or moderate use. We recommend cleaning the tip daily if the
station is used frequently. Remove excess solder in the tip retaining assembly to prevent the tip from
clogging.
The supplied soldering and desoldering tips are made of copper covered with a layer of iron. They will retain
their projected life span if used properly.
Always tin the tip before returning it to the holder, before turning off the station, or before storing it for
long periods. Wipe the tip on a wet sponge or use the included tip cleaner before activating the device.
Using excessive temperatures (more than 400 °C or 750 °F) will shorten the life span of the tip.
Do not exercise excessive pressure on the tip or rub the joint with the tip while soldering or desoldering. It
does not improve the heat transfer and may damage the tip.
Apply solder to the joint, not the tip, when soldering. The flux is caustic by nature and eats away the tip.
Never clean the tip with a file or with abrasive materials.
Do not use flux containing chloride or acid. Use only resinous fluxes.
If an oxide film has formed, you can remove it by buffing carefully with a 600–800 grit emery cloth or by
using isopropyl alcohol and then applying a new protective layer of solder.
For new tips: set the temperature to 250 °C (482 °F). When the temperature is reached, tin the tip, and
allow it to idle for three minutes. Then set the desired soldering or desoldering temperature and work
normally.
Important: Remove and clean the tip daily. Remove excess solder from the barrel nut assembly when
installing a new tip, otherwise the tip may be fused to the heating element or to the retaining assembly.
9.5 Possible Causes of Loss of Suction
Use the procedure outlined below to determine whether the loss of suction is due to the tip, to the solder
collector, the tube, or the in-line filters.
Warning! Set the power switch in the off position and allow the iron to cool before executing the procedure
below.
1. Disconnect the vacuum tube from the fitting on the front panel. Place your finger over the hole and depress
the vacuum switch. You should now have a strong vacuum. If not, return the station to the point of sale to
have the pump repaired.
2. Disconnect the in-line filters from the iron assembly. Depress the vacuum switch. Replace the filling of the
in-line filters if there is little suction, or if the filters are discoloured.
3. Remove the solder collector from the desoldering iron assembly. Place your finger over the hole of the
collector and depress the vacuum switch. Clean or replace the collector tube in case of insufficient suction.
4. Depress the vacuum switch and clean the tip with the included spring wire if there is no suction. See
Cleaning Clogged Tips for more information.

10.2 Operation
Precautions
To extend the life of the heating element in the hot air gun, do not use the device continuously at a low
airflow and a high temperature. Allow the heating element to cool after maximum 20 minutes of usage.
Place the hot air gun back in its stand when not in use.
Make sure that both heater and nozzle are cold before attaching the nozzle.
Warning! High temperature. Both nozzle and airflow are extremely hot and can cause severe burns.
Never touch the nozzle and heater assembly or allow the hot air to blow against your skin. When used for
the first time, the hot air gun may emit some white smoke, but this will soon dissipate.
Caution! Always let the unit cool down after use. After switching off, leave the power cord plugged in for a
few minutes. When you switch off the unit, the automatic cooling function blows cooling air through the
heater pipe for a short period. This protects the heater from damage and extends its lifetime. Do not
disconnect the mains plug during this cooling process.
Do not disassemble the pump. If the pump or other internal components become faulty, stop using the
device immediately. Contact your vendor or its authorised service centre for repair.
Setup
Caution! Do not force the nozzle or pull its edges with pliers. Do not over-tighten the screw.
1. Switch off the device. Wait until the automatic cooling process has stopped, and then disconnect the power
cord.
2. Wait until both heater and nozzle are completely cold.
3. Select the nozzle that matches the IC size.
4. Loosen the screw on the nozzle, slide the nozzle on the heater pipe, and fix it with the screw.
5. Plug in the power cord and switch on the station [1].
6. Press the ▲[17]or ▼[18]button to set the desired temperature.
Note: press and hold the ▲or ▼button to increase setting speed.
7. Press the ▲[22]or ▼[24]button to set the desired airflow.
Note: press and hold the ▲or ▼button to increase setting speed.

QFP Desoldering
1. Hold the nozzle directly over the IC and wait for the hot air to melt the solder.
Caution! Be careful not to touch the IC or the leads with the nozzle.
2. Once the solder has melted, remove the IC using pliers.
3. Clean the remaining solder chips with a wick or the desoldering iron.
QFP Soldering
1. Apply a suitable quantity of solder paste and flux (preferably no-clean) and place the SMD on the circuit
board.
2. Preheat the SMD.
3. Heat the lead frame evenly.
4. When soldering is finished, wash the area with a defluxer.
5. Inspect all joints carefully.
11. Cleaning and Maintenance
11.1 General
Perform only the maintenance as described in this user manual. Contact an authorised dealer or service
agent for any other maintenance or repair.
If the irons, gun, or station become faulty or, for some reason do not operate normally, return them to the
service department of your authorized dealer or service agent.
Clean the outer cover of the irons, gun, and station with a damp cloth and a small amount of liquid
detergent. Never submerge the unit in liquid or allow any liquid to enter the case of the station. Never use
any solvent to clean the case.
Use only original replacement parts.

VTSSD4
V. 01 –15/05/2014 11 ©Velleman nv
Replace cotton filters at least once every 3 to 5 days if you use the station 8 hours per day.
Replace charcoal filters at least every 3 weeks if you use the station 8 hours per day.
Replace the solder collector every 3 to 5 months. Handle the glass collector with care. It is fragile and can
break if you knock it against the desktop.
11.2 Replacing Soldering and Desoldering Tips
Soldering tips can be replaced simply by unscrewing the barrel nut assembly. Turn off the station and allow
it to cool down first. You can damage the soldering station if you switch it on without the tip in place.
After removing the tip, blow out any oxide dust that may have formed in the tip receptacle. Be careful not
to get dust in your eyes. Replace the tip and tighten the screw. You can use pliers to avoid contact with hot
surfaces but use with caution because over-tightening may cause damage to the element or fuse the tip
to the element.
11.3 Cleaning Clogged Tips
To prevent solder from clogging the desoldering tip, clean the desoldering tip after each use with the included
spring wire. This increases the tip life.
Proceed with care when removing the desoldering tip. You may damage the heater when you remove the tip
roughly when it is hot. You may use an anti-rust cleaner if the tip sticks to the heater. Never force.
Warning! To clean a clogged tip, you work on the tip while it is hot. Be very careful not to burn your fingers
when cleaning the tip.
To clean a clogged desoldering tip, proceed as follows:
1. Check if the spring wire (included) can pass through the desoldering tip nozzle.
2. If not, increase the temperature of the heating element so that the clogged solder can melt.
3. Slide the spring wire up and down until the passage is clear.
4. Unscrew the barrel nut assembly.
5. Use a pair of pliers to remove the tip.
6. Reinsert the stainless tube in the heating element to melt the solder. This takes approximately 5 seconds.
7. Remove the stainless tube and shake loose the molten solder.
8. Check if the tip is unclogged, then put it back in place and screw down the barrel nut assembly. Do not
over-tighten.

Fume Extractor Filter
Only use the fume extractor with the filter installed. The filter is located behind a grid that locks it in place.
To install or replace the filter in the fume extractor, proceed as
follows:
1. Make sure that the fume extractor is switched off and that the
power cord is unplugged from the mains.
2. Remove the grid [a] that holds the filter in place: push the
protrusions [b] inward and remove the grid from between the
fume extractor side flaps [c].
3. Remove the old filter [d] and place a new one in front of the
ventilator [e].
4. Place the protective grid back: slide the grid protrusions into
the notches in the flaps and gently click the grid into place.
