Weller WTL1000S User Manual

MODEL WTL1000S 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 in receptacle. Insert line cord
plug into properly grounded AC receptacle and turn station on. If the desired temperature key is not installed,
the key may be changed while power is on. 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
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.

A WCM1 Calibration Unit is available that interfaces directly with the WTL1000Ss microprocessor through the
iron receptacle and provides the ability to enable a timed setback mode, a temperature lock out feature, 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, turn the unit off and back on to return to normal operation.

WARNING: Do not remove ground prong from line cord plug. Removal may cause tip temperature

control to be erractic.

TROUBLESHOOTING GUIDE

WARNING: AC line voltage is present inside power unit even when power

switch is off. Refer service to qualified personnel.

NOTE: Access to internal parts may be gained by removing four rubber feet,

four screws under feet and top case.

TOOL DOES NOT HEAT

With line cord unplugged and power switch on, check for approximately 21 ohms at line cord blades for
120VAC units (55 ohms for 240VAC units).

 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.
 Check wiring to printed circuit board assembly - repair or replace if defective.
 Replace printed circuit board assembly.

With line cord plugged in and power switch on, check for 5 VDC ±1 VDC, between pins #3 and #4 of tool
receptacle

.

 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 soldering iron tech sheet.
