MODEL EC2002M ELECTRONIC SOLDERING STATION
WARNING: This product, when used for soldering and similar applications, produces chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
OPERATING INSTRUCTIONS
Unpack unit carefully. Place spring and funnel in slot in top of tool stand. Attach tool stand to either side of 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. When the tip temperature reaches 400°F (204°C), remove tool from holder and tin tip with solder. Unit will be ready for use when it reaches the set point temperature.
The unit display shows a “Read” mode by default which displays the current temperature of the tip. To switch into the “Set” mode, turn the knob slightly and the display will show the current set temperature. Release the knob when you have reached the desired temperature setting, and after a three second delay the display will switch back into “Read” mode. When you first turn the unit on, the display should show “888” for two seconds as a test and then will display the “Set” temperature for three seconds before switching into “Read” mode.
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 no 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.
While the unit is in the “Read” mode, the displayed tip temperature may fluctuate. This fluctuation is normal and represents the control system response to the changing load. Tip selection for a particular job may be optimized by observing the tip temperature fluctuations during the soldering operation. Normally, the tip should be selected for minimum fluctuation. This will provide the shortest soldering dwell time; however, some applications may require a fast response with total fluctuation not critical.
A WCM1 Calibration Unit is available that interfaces directly with the EC2002M’s microprocessor through the iron receptacle and provides the ability to enable a timed setback mode, a temperature lock out feature, a switch to change the display measurement between °F and °C, digital calibration of the unit to an outside temperature reference, and reset the unit to its original factory calibration. When the unit enters “Setback” mode, the unit display will highlight the bottom segment of all three digits. Turn the unit off and back on to return to normal operation. If the unit is locked to a specific temperature, this temperature may be checked, but not altered, by turning the knob.
WARNING: Do not remove ground prong from line cord plug. Removal may cause tip temperature to be erratic.
CALIBRATION
The EC1201A, EC1302B and EC1503B soldering tools use high precision platinum RTD temperature sensors; therefore, they are interchangeable without any re-calibration. Should you wish to custom calibrate your EC2002M unit, this can be easily accomplished with the use of a WCM1 Calibration Unit and a temperature measurement device like the WA2000.

With line cord unplugged and power switch on, check for about 21 ohms at line cord blades for 120VAC units (55 ohms for 240VAC unit).
• Check fuse, located on bottom of case – replace if required. Use slow blow fuse – 0.6A for 120VAC (0.3A for 240VAC).
•Check power switch – replace if defective.
•Check line cord – repair or replace if defective.
•Check transformer primary – replace transformer if defective.
With line cord plugged in and power switch on, check for 24VAC ±10% between pins #1 and #4 of tool receptacle.
•Check transformer secondary for 24VAC ±10% - replace transformer if defective.
