To all residents of the European Union
Important environmental information about this product
This symbol on the device or the package indicates that disposal of the device after its lifecycle could harm
the environment.
Do not dispose of the unit (or batteries) as unsorted municipal waste; it should be taken to a specialized
company for recycling.
This device should be returned to your distributor or to a local recycling service.
Respect the local environmental rules.
If in doubt, contact your local waste disposal authorities.
Congratulations ! You have selected the ideal solution for all your soldering applications ! We are confident that the
versatility of this desoldering station and its many special features will satisfy your every need. It is not surprising,
therefore, that the VTDESOL4 has been one of the electronics industry's favourite desoldering tools for the last 15
years. We advise you to read this instruction manual carefully. This will enable you to maximise the advantages of
your new desoldering station.

2. Special Features

• ENERGY SAVER : this new feature will automatically be activated whenever the desoldering station remains
unused for more than fifteen minutes. The "Pause" LED will light up, indicating that the temperature of the tip has
been reduced by 1/3. This reduces power consumption and extends the life of the tip.
• DELAYED SUCTION : This feature allows the pump to continue its suction for 1.5 seconds after the control switch
has been released. This eliminates the problem of solder clogging the tip.
• DIGITAL DISPLAY : This new feature provides the user with accurate temperature readings. Once the installed
temperature has been reached, the "Set/Read" button can be flipped to the "Read" position. This ensures a
constant temperature.
• CELSIUS/FAHRENHEIT SWITCH : Enables the user to switch from °C to °F and vice versa.
3. Description
The VTDESOL4 is equipped with a self-contained, temperature-controlled vacuum pump. The vacuum pump is
maintenance-free. It will not overload with continuous use. The vacuum pump provides a max. suction of 50cm/Hg
(20"/Hg) and is activated by a push-button switch located on the iron housing.
The VTDESOL4's electronic circuitry enables you to use tip temperatures ranging from 300°C to 450°C (572°F to
842°F) without having to change the tip or the heating element. The temperature readout can be switched from °C to
°F or vice versa simply by flipping a switch on the front panel. The temperature is maintained to within ± 3°C (± 6°F)
of the normal operating temperature through a thermocouple sensor located in the heating element. Consequently,
even the smallest temperature variations of the tip are monitored and the temperature is rapidly corrected whenever
necessary. The revolutionary "zero voltage" switching design also protects voltage- and current-sensitive
components (CMOS devices, etc.) against the damaging currents and transient voltage spikes commonly produced
by less efficient, mechanically switched desoldering stations.
The heating element heats up very quickly and temperature corrections are executed swiftly The heating element is
galvanically isolated from the electrical supply by an isolating transformer that prevents the system from using a max.
tension higher than a (safe) 32VAC.
