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.

The Weller WES51 Electronic Soldering Station is a microprocessor-controlled device designed for industrial manufacturing, rework, and repair. It offers precise temperature control and a range of features for efficient soldering.

Function Description:

The WES51 Soldering Station provides a controlled heat source for soldering applications. It features a digital electronic control system that allows users to adjust the tip temperature and maintain it with high accuracy. The station is equipped with a grounded soldering iron tip, zero power switching, and an anti-static design, ensuring compliance with Weller's quality standards. A unique feature is its automatic sleep mode, which shuts off power to the tool and indicator LED after 99 minutes of inactivity, conserving energy and extending tool life. The station also includes an external tip temperature offset and a lockout feature, which allows users to set and lock the tip temperature using the supplied PW50 Probe.

Important Technical Specifications:

• WES51 units are UL/CUL listed and meet all applicable standards for CE mark.

Usage Features:

• Temperature Adjustment: Tip temperature is adjustable from 350°F to 850°F (177°C to 454°C) using the front panel control knob.
• LED Power Indicator: The LED indicates station status:
  • "Green" for normal operation (unlocked mode).
  • "Red" if the temperature is "Locked".
  • Full "On" (Green or Red) indicates the station is ramping up to temperature.
  • Full "Off" or flashing steadily (Green or Red) indicates the station has reached the "Set Point".
• Lockout Feature: The temperature setting can be locked to prevent accidental changes. To activate, apply the Lockout Pencil to the ESD symbol until the LED blinks "Red" slowly (5 Hz), then remove the pencil within 2.5 seconds. The LED will turn "Red", and the control knob will have no effect. To reverse, repeat the process; the LED will turn "Green", and the knob will function normally.
• Tip Temperature Offset: This feature allows users to fine-tune the tip temperature for specific applications. It involves monitoring the tip temperature with a K111 Type "K" Thermocoupled Tip temperature test kit, adjusting the set knob, and then applying the Lockout Pencil to the ESD symbol until the LED blinks "Red" then "Green" slowly.
• Auto Off Feature: The station automatically shuts off power to the tool and LED after 99 minutes of inactivity.
• Optimal Temperature Use: Users are advised to use the lowest temperature that can handle the soldering load. The electronic control provides maximum power even at lower temperatures, protecting sensitive components from heat damage.
• Tool Stand: The unit includes a tool stand with a spring and funnel for convenient tool placement and tip cleaning.

Maintenance Features:

• Troubleshooting Guide: The manual provides a comprehensive guide for troubleshooting common issues such as the tool not heating, tool overheating, and tip temperature testing errors.
• Internal Access: Access to internal parts for service is gained by removing four rubber feet, four screws under the feet, and the top case.
• Component Checks: The guide details checks for line cord continuity, power switch continuity, transformer primary and secondary voltages, wiring to the printed circuit board, and tool receptacle connections.
• Tip Care:
  • Keep the tip tinned and wipe only before using.
  • Use rosin or activated rosin fluxes; avoid acid-type fluxes.
  • Remove and clean the tip regularly with a suitable cleaner. If the tip does not remove easily, do not force it; try removing it while heated, or return the tool for service.
  • Avoid cleaning the tip with abrasive materials or filing it, as this reduces tip life.
  • If the tip becomes unwettable, clean it hot with a soft steel or brass brush using solder flux, or with a Weller® WPB1 polishing bar when cold, then immediately re-tin.
  • Do not remove excess solder from the heated tip before storing to prevent oxidation.
  • Avoid using compounds or anti-seize materials on Weller® tips or sensor probes, as this can cause wettability problems and seizing.
• Replacement Parts: A list of replacement parts and accessories is provided, including power switches, circuit board assemblies, transformers, heating elements, and various soldering tips.
