This manual is structured to enable a technician with no
previous knowledge of the system, to become familiar with
the operation and maintenance of the equipment. The
safety section of the manual explains the inherent dangers
presented by any type of desoldering/soldering equipment
and warnings to minimize the risk of injury through igno

ChangingFuses
●Fuses should only be changed with the equipment switched
off,andtheequipmentisolatedfromtheelectricalsupplyby
removingtheIECplugfromthemachine.
●The fuse of the main unit is located at the back of the
equipment and is changed by withdrawing the fuse holder
andwithdrawingthefuse.
●Onlyreplacewiththesametype,sizeandvalue.Thecorrect

ChangingtheI.R.Lamp
●Unplugtheunit.
●Withdrawthelampfromthehousing.
●Fitreplacement
●Be careful to handle only the outside edges of the glass
reflector.
Note: If the bulb within the lamp is touched then the lamp may
failprematurely.

WARNING: All cleaning and/or maintenance should be
performed when the machine is switched off and isolated
from the main supply. The system must have been allowed to
cool down to room temperature so as to avoid burns or
other damages from hot parts of the machine.

REWORKING TIPS
●UseFluxGel.Whenitturnsfromagelintoafluid/liquid,this
indicates that the PCB is preheated and you can apply heat
using the Solderlight gun. Flux Gel also helps placement of
thecomponent.
●If the Preheater temperature is too low or preheating time
too short,whenyou apply the Solderlight gun,theheat will
be conducted away by the PCB's ground plane, which will
increasethetimeittakestoreflow.
●ThelongerthepreheatthePCBthelessTopHeatyouneed.
●Whenthesolderisfullymolten,tapthePCB,andwatchthe
surface tension of the solder draw the component into per

Preheater
The Preheater's function is to preheat the PCB and component;
thisprotects thePCB fromdelaminating andthe componentfrom

balance of heat energy supplied should be approximately 75%
fromthePreheaterand25%fromtheSolderlightgun.
