SAFETYPRECAUTIONS
A\ CAUTION
When power is ON, tip temperatures willbe between200and 480°C. To avoid injuryor
damage to personnelanditems inthe workarea,observe the following:
• Donottouch thetipor themetalpartsnearthe tip.
• Donotallowthe tipto comecloseto, or touchflammablematerials.
• Informothers inthe area that theunit ishot andshould not betouched.
• Turn the poweroffwhen notin use or left unattended.
• Turn the power off whenchangingparts or storing the station.
To preventaccidents or damage tothe station,besure to observe the following:
• Do not use the station for applicationsotherthansoldering.
• Donotallowthe station to become wetor use it whenhandsare wet.
• Donot strike the ironagainsthardobjects to removeexcesssolderas this will
damage the iron.
• Remove powerandironcords by holding the plug — notthewires.
• Besure the workarea is well ventilated.Solderingproducessmoke.

CONTROLS,DISPLAY & BUZZER
A.Controls
The frontpanel of thesoldering station has the followingcontrols:
- Resetbutton
- Increases the value of the set temperature
- Decreases the value oftheset temperature
B.Display
The station has a three-digitdisplayelementand a heaterlamp.
-3£5VHeaterlamp
Depending upon the selected mode, the three-digitdisplay will indicate:
• Normal mode: sensortemperature in °C (tip temperature)
• Dataentry
• Errordetection
The singleheaterlamp will blinkwhen the station increasesandreaches
itsset temperature. No blinkingshall be noticedwhen the temperature
isdecreasing.
C.Buzzer
An audible buzzer is provided to alert the operatorwhen:
• The station hasreached theset temperature.
• A failurehasoccurred inthe sensor or heater(including the sensor
circuit). The buzzer will soundcontinuously.
• The30-minutesleepmode is activatedand the power tothe heating
element is shut off.
•Thestationremainsabove460°Cfora longperiodoftime.
/j\ Thesolderingstation is preset at 350°C.Thesolderingirontemperaturewillrise to

OPERATION
A.Changingthetemperaturesetting
1. Turn the power ON. When errorsignalbeep is heard, press the resetbutton.
2. Press theΟ andΟ button tosetthe desiredtemperature in degreesCelsius.
NOTE: Temperaturecanbe setfrom200 -480°C. Anincrement/decrement of20 C
willbeset whenever the temperatureadjustingbutton is pressed.Pressbutton
steadily for largedifference in desiredtemperature.
Λ Tiptemperaturerisesquickly to desiredsetting. A beepsound willbe heard

Replacingthe tip
1. Always turn the power OFF whenremoving or inserting atip.
2. When thetipis hot,hold it with the heatresistantpadandpull itout.
3. Insert the new tip fully into the handle, If the tipis not fully inserted, the display
will show a sensorerrorwhenpower is turned on.

2. Cleaning
Alwayscleanthesolderingtipbeforeusetoremoveanyresidualsolderor flux

B.CheckingProcedure
Δ
Unless otherwisedirected,carryouttheseprocedures with thepower switch
OFF andthepowercord UNPLUGGED.
• Checkfora brokenheater
Verifythe electrical integrity oftheheaterand
sensor. Measuretheresistanceoftheheater
and sensorwhileatroomtemperature.It
should be 7.5-12Ω. Iftheresistanceexceeds
these limits, replacethetip.
• Checkthegroundingline
1. Unplugthesolderingironcordfromthestation.
2. MeasuretheresistancevaluebetweenPin3 andthe
solderingirontip.
3. Ifthevalueexceeds 2 Ω (atroomtemperature),perform
tipmaintenance.Ifthevalue still doesnotdecrease,
checktheconnectioncordforbreakage.
