TROUBLESHOOTING GUIDE
MainFuse
This should be checked first when any malfunction arises. The
fuse (20mm,T/Antisurge,l0Amp), islocatedattheback ofthe
controlleradjacenttothe.
BulbError
Thismaybecausedbyeitherablownfuse,thelamp'sage,cor
rodedlamppinsoradefectivelampsocket.
LampAge/Life
Alamphasalifeexpectancyof30,000cyclesor50hoursatfull
power.Ifburntinappearance,replacewithanewlamp.
Corrodedlamppins
Check the lamp pins and socket for corrosion. Residue on the
pinsofthelampmaypreventpropercontactbetweenthelamp's
pinsandthelampsocket.Therefore,removethelampandclean
thepinslightlywithabrasivepaper.
Preheatermalfunctions
Thismaybe caused byeitherablown mainsoraproblemwith
theconnections.CheckifthePreheaterisproperlyconnectedto
the(mainunit)controller.

REWORKING TIPS
●UseFluxGel.Whenitturnsfromagelintoafluid/liquid,this
indicates that the PCB is preheated and you can apply heat
using the Solderlight gun. Flux Gel also helps placement of
thecomponent.
●If the Preheater temperature is too low or preheating time
too short,whenyou apply the Solderlight gun,theheat will
be conducted away by the PCB's ground plane, which will
increasethetimeittakestoreflow.
●ThelongerthepreheatthePCBthelessTopHeatyouneed.
●Whenthesolderisfullymolten,tapthePCB,andwatchthe
surface tension of the solder draw the component into per
fectalignment.
! Reminder:Alwaysputonweldinggoggleswhilereworking.

TECHNICAL DESCRIPTION
InfraRedLamp 
The200WattInfraRed(I.R.)lampislocatedinthelamphousing
at the front end of the hand unit. The lamp emits mostly short
waveI.R.radiationatapproximately1.0micronwavelength. 
TopHeat 
Thetopheataddsheattotheprocessandbringsthesolderjoint
temperature up to reflow. The heating process of the Focused
Infrared Welding system is a combination of the Solderlight gun
andthePreheater.ThePreheaterheatsthePCB,pads,andleads
of  the  component  up  to  120140° C  and  the  Solderlight  gun
increasesthetemperaturefurtheruntilyoureachreflow. 
WhatSolderlightguntemperatureshouldyouuse? 
Between180380°C.Onlyincreasetheguntemperature afteryou
haveincreasedthePreheatertotherequiredtemperature.Always
preheat the PCB (between 30 90 seconds) to allow the heat to
conduct through the component before applying the Solderlight
gun. 
What's the working distance of the Solderlight gun and how do I
moveitforrework? 
Approximately 510mm when reworking and move up to 30mm
when removing Component  move the hand tool in a scanning
motiontoheatleads,takingaboutonesecondforeachscanofthe
component.

TECHNICAL DESCRIPTION
Continuation
Preheater 
The Preheater's function is to preheat the PCB and component;
thisprotects thePCB fromdelaminating andthe componentfrom
thermalshock.ThePreheateralsoequalizestheconductiveeffect
ofthegroundplaneofthePCB.
The ceramic heater  preheats  the PCB  and  the heat conducts
throughthePCBandpreheatsthecomponent,sowhenyouapply
the Solderlight gun  there is no chance of thermal shock. The
balance of heat energy supplied should be approximately 75%
fromthePreheaterand25%fromtheSolderlightgun. 
WhatBackHeatsettingshouldyouuse? 
Generally180°Csetonthe Preheaterisagood startingpoint.If
theprocesstakeslongerthan180secondsthenincreasethePre
heaterby20°Cincrementstoreducetimetaken.Withthecorrect
PreheatersettingthetopofthePCBwillreachapproximately120
140°Cinabout60120seconds. 
Whydoweneedthegoggles? 
Thegoggleshastwomajorfunctions,oneistoenableyoutosee
thefocusedinfraredlightforprecisionsoldering,theotherfunction
istoprotectyoureyesfromharmfuleffects.
