WARNING: This appliance is not intended for use by children or other persons .
without assistance or supervision if their physical, sensory or mental capabilities
prevent them from using it safely. Children should be supervised to ensure that they
do not play with the appliance.
KEY FEATURES
. ENERGY SAVER: If the station has been idle for more than 15 minutes, it will
automatically kick in. When the "Pause" LED is lit, the energy saver feature has
engaged, decreasing tip temperature by 1/2 which cuts power consumption and
extends tip life (note that lead free solder alloys require a higher soldering
temperature which shortens tip life). Activating the solder wand will disengage the
power saving feature and the unit will immediately ramp up to the preset
temperature.
. DIGITALDISPLAY: This new feature was incorporated into the LF-1000 to provide
timely and accurate temperature readings. Once the desired temperature is
reached, the Set/Read button can be flipped to the" READ" position, insuring a
constant temperature. J
. CELSIUS/FAHRENHEITSWITCH: To address the global market place, a
convenient switch has been incorporated to easily convert from one common
measure to another.
. ISOLATED IRONHOLDERWITH TIP CLEANER: Made of low abrasive brass
shavings instead of conventional sponges to meet RoHS requirement, cleans ;
better and no water is necessary. .
. LOW VOLTAGE OUTPUT WITH SAFETY OPERATION: The power unit is isolated
from the A.C. line by a transformer and allows 32Vac to drive the heating element.

PRODUCTION DESCRIPTION .
TheLFserieshighpowerelectronicallytemperaturecontrolledsolderingstationwere ;;
spcially designed and developed to meet the present and future Lead-free soldering
needs of the electronic production industry. A temperature regulated soldering iron is
essential for marking consistent, reliable soldered connections. It provides all the
benefits of temperature regulation and connects via a highly flexible burn-resistant
lead,and can be easily adjusted in temperature.
The LF series incorporates electronic circuitry which enables the user to alter tip
temperature from 200 to 450'C(392-842'F) without changing tips or heating elements.
Also, with the simple flip of a switch on the front panel, the temperature readout is
changedfrom Celsiusto Fahrenheiteasily. The temperatureismaintained within '""
:t 3 'c (:t 6 'c ) of its operating temperature by a thermocouple sensor placed in the
heating element, allowing the tip to rest against the sensor. The high power results in
both a rapid heat-up and super fast recovery.
The revolutionary "Zero Voltage" electronic switching design also protects voltage
and current sensitive components (CMOS devices, etc.) against damaging current and
transient voltage spikes commonly produced by less efficient, mechanically switched
stations. The power unit is isolated from the A. C. line by a transformer and allows
only 32Vac to drive the heating element.An external calibration port on the face of the
unit for quick and convenient precision temperature adjustments. The many features ,"i~
of the product make it the ideal tool for service and repair technicians as well as
production line soldering operations. This unit is developed to meet the present and
future lead-free soldering needs of the electronic production industry and is ideal for
use at any AC outlet.

Usingthe soldering pencil will deactivate the energy saver feature and the unit will
immediately ramp up to the preset temperature"
Precision Calibration: There is a calibration port under the digital display on the front
panel.This calibration is to be used in conjunction with an external thermometer"
/"Place the tip on the thermometer and if the actual tip temperature reads higher or
lower than the display on the thermometer then use a 2mm precision screwdriver to
calibrate the temperature. Turning clockwise will lower the temperature (-).Counter .
clockwise will increase the tip temperature (+).
Caution: Soldering irons operate at hightemperatures and can easily burn people or
I objects. Do not touch the tip and heater at any time and keep it a safe distance from
r flammable materials while the unit is on or while its cooling.
Please allow a sufficient time for it to cool before changing tips or servicing the unit!
COMMON CAUSES OF TIP UNWETTING
1. Tip temperature higher than 410°C (770°F).
2. The tip working surfaces are not tinned while the iron idles.
3. Lack of flux in soldering, wicking, repairing, and touch-up operations.
4. Wiping the tip on a high sulfur content, dirty or dry sponges and rags.
5. Touching with organic substances such as plastic, resin, silicone, grease or other
chemicals.
6. Impurities in solder and/or low tin content.
CARE OF TIPS
Caution: The soldering iron can reach very high temperatures. Be sure to turn the unit
off prior to carrying out any maintenance or trouble shooting steps listed below.
IMPORTANT
Remove the tip and clean after moderate to heavy use or at least daily for light usage.
Remove any loose build up in the tip retaining assembly to prevent tip freezing.
The solder tips supplied are iron clad copper and if used properly should maintain
Ioptimum operational life.
1. Always tin the tip before returning it to the holder, turning off the station, or storing
it for long periods of time. Wipe the tip on a brass cleaner (XY459) prior to use.
2. Keeping the iron set at hightemperatures (more than 400°Cor 750°F) will shorten
tip life.
3. Do not use excessive pressure to the tip or rup the joint with the tip while soldering.. ...~,
it does not improve the heat transfer and may damage the tip. (f
4. Apply solder to the joint, not the tip when soldering. The flux is naturally caustic
and thus will eat away the tip.
5. Never clean the tip with a file or abrasive materials.
6. Do not use fluxes which contain chloride or acid. Use only rosin or resin activated
fluxes.

7. If an oxide film forms on the tip, it can be removed by careful buffing with a
600-800 grit emery cloth, isopropyl alcohol or equivalent and then wrapping rosin
core solder around the newly exposed surfaces. Coat the tinned areas with
rosin-core solder after the resin-core has melted.
NEW TIPS
Applying the following steps will lead to optimum life. .
1. Set temperature to min.then turn the main power switch to the" ON" position.
2. Settemperatureto 250'C(482'F).
3. Coat the tinned surfaces with rosin-core solder after reaching 250'C (482'F).
4. Set to desired temperature after allowing the unit to idle at 250'C for 3 minutes.
5. The iron will be ready for use once it reaches the preset temperature.
IMPORTANT:Remove and clean the tip daily. If a new tip is installed, remove any
loose build up in the barrel assembly, otherwise the tip may fuse to the heating
element or retaining barrel.

MAINTENANCE
TIP MAINTENANCEAND DRESSING
Tips can be changed or replaced simply by unscrewing the knurled nut barrel
assembly. The station must be switched off and allowed to cool before this operation
as damage may result if the system is left on without the tip in place!
After removing the tip, blowout any oxide dust that may have formed in the tip
retaining area of the barrel. Be careful to avoid getting this dust in your eyes. Replace
the tip and screw back the knurled nut barrel assembly using only firm hand pressure .
to tighten. Pliers should only be used to tighten the nut to avoid burning your fingers,
but care should be taken not to over-tighten as this could damage the element.
GENERAL CLEANING
The outer cover of the iron and station may be cleaned with a damp cloth using small
amounts of liquiddetergent. Never submerse the unit in liquid or allow any liquidto
enter the case of the station. Never use any solvent to clean the case.
SERVICE
If the iron or station should become faulty or, for some reason not operate normally,
the system should be returned to the service department of your authorized dealer or
service agent or similarly qualified person in order insure proper repairs and to avoid
any hazards from developing.
WARNING: This iron must be returned to its stand when not in use.
WARNING: Keep out of the reach of children.
WARNING: Do not inhale solder fumes.
WARNING: Keep tip and heating element away from the body, clothes and
flammable material when in operation.
