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.

Complete instructions are provided with replacement part. 4 1.2 Check sensor resistance from pin 3 to pin 4 of the tool connector, should measure 1 - 2 ohms. 1.2.1 If sensor resistance is incorrect, remove heater/sensor assembly from handle and check at the sensor leads (see PES201 Replacement Heater Instruction Sheet). 1.2.2 Replace cord/handle assembly if sensor is correct; else replace heater/sensor assembly. 1.2.3 Check resistance from pin 3 to pins 2 and 6 of the tool connector, should measure 1 megohm minimum. 1.2.4 Remove heater/sensor assembly from handle and check for shorts in wiring inside handle. Repair or replace as required. 2. Tool overheating. (NOTE: Tool will overheat with tip removed). 2.1 Check resistance from pin 3 to pin 4 of the tool connector, should measure at least 1- 2 ohms. 2.1.1 Remove heater/sensor assembly and check for shorts in wiring inside handle. Repair wiring as required, or replace cord/handle assembly. Complete instructions are provided with replacement part. 3. High voltage on tip. 3.1 Check resistance from pin 5 of the tool connector to tip, should measure 2 ohms maximum. 3.1.1 If tip ground is open, remove heater/sensor assembly and check continuity of ground wire in cord. 3.1.2 Repair wiring as required, else replace cord/handle assembly if open. Weller® ET and SMT series tips are solid Copper, plated with Iron, Nickel and Chromium. The Nickel and Chromium protect the shank from corrosion and solder creep. The tips are pre-tinned in the working area with solder. Use only Weller® soldering tips. Use of non-Weller® components may void product warranty if the non-Weller® component causes damage to the unit. Consult tool and tip selection sheet for available tip styles. 1. Keep tip tinned; wipe only before using. 2. Use rosin or activated rosin fluxes. Acid type fluxes will greatly reduce tip life. 3. Remove tip and clean with suitable cleaner for flux used. The frequency of cleaning will depend on the type of work and usage. Tips in constant use should be removed and cleaned at least once a week. Corrosion between tip and sensor can cause erratic temperature control. WARNING: If tip does not remove easily, do not force it. The sensor will be damaged. Try removing the tip while heated. If this does not work, return tool to Weller ® for service. When installing new tips, they should slide freely over sensor probe. 4. Dont try to clean tip with abrasive materials and never file the tip. To do so will greatly reduce tip life. Tip wettability is affected by contact with organics; such as plastic resins, silicone grease, and other chemicals. If the tip be comes unwettable, it may be cleaned hot with a soft steel or brass brush using solder flux as a solvent; or with a Weller® WPB1 polishing bar (use only when the tip is cold). Do not over do this or the iron plating will be removed and the tip ruined. Re-tin tip immediately after cleaning to prevent oxidation. 5. Do not remove excess solder from heated tip before storing. The excess solder will prevent oxidation of the wettable surface when tip is re-heated. 6. Do not use any compound or anti-seize material on Weller® tips or sensor probe. This may cause wettability problems and may cause seizing after extended heating periods. 5 REPLACEMENT PARTS AND ACCESSORIES KEY NO.
