MODEL WES50 ELECTRONIC SOLDERING STATION
DESCRIPTION
The WES50 Soldering Station is part of the range of product which have been developed for industrial manufacturing as well as for the repair sector. A microcontroller makes operation simple and easy. The digital electronic control system guarantees good control performance for various soldering jobs.
A grounded soldering iron tip, zero power switching and anti-static design of the station and tool completes the high quality standard. The station features tip temperature calibration and the ability to lock the tip temperature setting; and the station will enter a sleep mode and shut off power to the tool and indicator LED after 99 minutes of inactivity.
Tip temperature is set in the range of 350°F to 850°F (175°C to 455°C) with the front panel knob and the LED power indicator will be green for normal operation or red if the temperature is locked. This soldering station is CUL approved and meets all applicable standards.
OPERATING INSTRUCTIONS
Unpack unit carefully. Place spring and funnel in slot in top of tool stand. Attach tool stand to either side of the power unit, if desired. Fill reservoir with water and wet sponge, distilled water is preferred. Insert tool in holder and connect tool plug to receptacle on power unit; rotate plug housing 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 now ready for use.
Always use the lowest temperature that will handle the load you are soldering. The Weller® electronic control provides maximum power to the heated load even when set to the lowest temperature; therefore, there is not need to use high temperature 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.

ACTIVATION OF LOCKOUT FEATURE
1.Set the temperature set knob to the desired tip temperature.
2.Apply the Lockout Pencil to the ESD symbol on the front panel until the LED starts slowly (5 hz/sec) blinking red; remove the Lockout Pencil within 2.5 seconds and the temperature setting will be locked in. The indicator LED will be red and turning the temperature set knob will have no effect on the tip temperature.
3.Reverse the lockout by applying the Lockout Pencil to the ESD symbol until the LED is slowly blinking red; remove the Lockout Pencil within 2.5 seconds and the temperature set knob will function normally and the indicator LED will be green.
TIP TEMPERATURE CALIBRATION PROCEDURE
1.Monitor the tip temperature with a 30 gauge thermocouple resistance welded to the center of the wetted area, tinning should be removed before welding. K-111 temperature test kits are recommended; see Replacement Parts and Accessories Section.
2.Set the temperature set knob to the desired tip temperature and allow the tip temperature to stabilize.
3.Apply the Lockout Pencil to the ESD symbol on the front panel. The LED should slowly blink red for 2.5 seconds and then slowly blink green; set the temperature set knob to the observed tip temperature, remove the Lockout Pencil, and the calibration procedure is complete.
RESET STATION TO FACTORY NOMINAL CALIBRATION
With station turned off, set temperature set knob to 600°F (315°C), apply the Lockout Pencil to ESD symbol on front panel and turn station on. Remove the Lockout Pencil and the procedure is complete. Any tip temperature calibration programmed above will reset.
7. Use the appropriate soldering tool.
With line cord plugged in and power switch on, check for 24VAC ±10% between pins #2 and #4 of tool receptacle.
•Check transformer secondary for 24VAC ±10% - replace transformer if defective.
•Check wiring to printed circuit board assembly - repair or replace if defective.
•Replace printed circuit board assembly.
Check wiring from tool receptacle to printed circuit board.
•Repair or replace if defective.
Replace soldering tool with known good tool and recheck.
• Troubleshoot soldering tool using guide in tool tech sheet. Replace printed circuit board assembly.
TOOL OVERHEATING
Replace soldering tool with known good tool and recheck.
• Troubleshoot soldering tool using guide in tool tech sheet. Replace printed circuit board assembly in station.
TIP TEMPERATURE TESTING ERRORS
NOTE: Tip temperature testing must be done using 30 gauge thermocouple wire resistance welded to the center of the wetted area on the tip, tinning should be removed before welding. Other methods, or heavier thermocouple wire, will cause errors. K-111 temperature test kits are available; see Replacement Parts and Accessories Section.
Replace soldering tool with known good tool and recheck tip temperature.
• Troubleshoot soldering tool using guide in tool tech sheet. Calibrate station according to Tip Temperature Calibration Procedure.
