VT-DESOL2 GB
2
This desoldering station is designed to meet the present and future needs of the electronic
production industry and is ideally suited for use with any AC outlet. Engineered to meet the
stringent demands of hobbyists, maintenance personnel and production people alike, the VT-
DESOL2 sets a new quality standard for desoldering equipment.
4. Operating Temperature
SOLDERING
The most common solder 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.
Melting point
: 215°C
or
419°F
Normal operation
: 270-320°C
or
518-608°F
Production line operation : 320-380°C
or
608-716°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.
DESOLDERING
Recommended tip temperatures are detailed below. They can vary from joint to joint.
For a small joint : 320-360°C or 608-680°F
For a larger joint : 370-400°C or 698-752°F
If the temperature is too low, the solder will flow too slowly and this may cause the tip to clog ;
you may burn the PCB if the temperature is too high.
5. Operating Instructions
Verify whether the operating voltage of the unit is identical to that of the electrical supply. Make
sure the device was not damaged in transit.
OPERATING PROCEDURE FOR DESOLDERING ACTIVITIES
(a) Plug in the desoldering iron and connect the vacuum tube to the DIA-connections on the
front panel.
(b) Connect the AC power cord to the mains inlet.
(c) Place the temperature control knob in the "MIN"-position.
(d) Place the power switch in the "ON"-position. The pilot lamp will light up.
(e) Set the temperature control knob to 250°C (482°F). Tin the surface of the nozzle of the
desoldering tip by applying a new protective layer of solder.
(f) Set the temperature control knob to the desired temperature 3 minutes after the station has
reached a temperature of 250°C (482°F). The unit is ready for use when it reaches the
preset temperature : the pilot light will extinguish at this time.
NOTE : The energy-saving feature will automatically engage if the desoldering station remains
inactive for more than 15 minutes (indicated by the green "PAUSE" indicator light). The
