MODEL WES51 ELECTRONIC SOLDERING STATION
DESCRIPTION
The WES51 Soldering Station is one in a series of products, which have been developed for industrial manufacturing as
well as for the rework and repair sector. The microprocessor control allows for simple and easy operation. The digital
electronic control system offers excellent control performance for various soldering jobs.
A grounded soldering iron tip, zero power switching and anti-static design of the station and tool allows the WES51
Soldering System to meet the high quality standards established by Weller
®
. The station features external tip temperature
offset and the ability to lock the tip temperature setting using the PW50 Probe supplied. The station will automatically
enter a sleep mode and shut off power to the tool and indicator LED after 99 minutes of inactivity.
Tip temperature is adjustable in the range of 350°F to 850°F (177°C to 454°C), with the front panel temperature control
knob. The LED power indicator will be Green for normal operation or Red, if the temperature is Locked. The LED for
the WES51 will also indicate the operation of the station by the following sequence: Indicator LED full On, indicates that
the station is ramping up to temperature (this can be indicated in either the Green Unlocked mode or the Red
Locked mode). Indicator LED full Off or flashing steadily, indicates that the station has reached the Set Point (this also
can be indicated in either the Green Unlocked mode or the Red Locked mode). This soldering station is UL/CUL
listed and meets all applicable standards for the CE mark.
OPERATING INSTRUCTIONS
Unpack unit carefully. Place spring and funnel in slot in top of tool stand. Dampen the sponge, distilled or de-ionized water
is preferred. Insert tool in holder and connect tool plug to receptacle on power unit; rotate plug housing Clockwise (CW) to
lock plug into receptacle. Insert line cord plug into properly grounded AC receptacle and turn station On. Set
temperature control knob to desired tip temperature. Wait 30 seconds. Remove tool from holder and tin tip with solder. Unit
is ready for use once the LED begins to flash, indicating that it has reached the operating temperature (indicated in either
the Green or Red mode).
Always use the lowest temperature that will handle the load that you are soldering. The Weller
®
electronic control provides
maximum power to the heated load even when set to the lowest temperature; therefore, there is no need to use high
temperatures to handle heavy soldering loads. By using lower temperatures and properly selecting tip styles, sensitive
components will be protected from heat damage.
WARNING: Do not remove ground prong from line cord plug. Removal may cause tip temperature control to be erratic.
