4. Flow a small
amount of solder
onto the joint. The
solder joint should
have enough
solder to hold
the component,
but should not extend beyondthe pad and should
extend only slightly above the pad.
5. Trim the excess lead as
closely as possible to the
PCB.
Caution: Be careful when
soldering and trimming
leads. Protective eyeware is
recommended.

Before You Begin
Instill good working habits. A soldering iron is not a toy.
• Prepareaclean,unclutteredworkspacewithno
distractions.
• Verifyalltoolsandparts.
• Reviewschematicsandinstructions.Attentiontodetail
is critical.
Cleaning Your PCB
Copper on the printed circuitboard (PCB) may oxidize
when exposed to oxygen and moisturein the air. This
oxidation can result in poorly connectedwelds. Before
soldering, use a scouring pad to gentlyclean the copper
surface so it is uniformlyshiny. This will enable the solder
to properlyadhere to the PCB.
Preparing Your Soldering Iron
1. Place your soldering ironon
the stand.
2. Plug the soldering iron into
a wall outlet.
Soldering
1. Insert the component leads
through the correctpads on
the PCB.
2. Press the iron tothe pad
where the lead emerges. Heat
the pad for a few seconds,
sothatthesolderwillow
smoothly and evenly.
3. Do not move the iron. Instead,
touch the solder to the point
where the iron, pad, and lead
all meet.
Leads
Tin the Soldering Iron Tip
“Tinning” means coating the soldering irontip with a small
amount of solder.
1. Plug in the iron and
wait three minutes.
2. Tin the soldering tip
by adding a small
amount of solder.
Important Safety Instructions
• Readinstructionsbeforeoperatingtheproduct.
• Keepoutofthereachofchildren.
• Workonlyinadryareathatisfreefromammablematerials.
• Operatethesolderingironinproperlyventilatedroomsorrooms
with a fume extractionsystem. Inhalation of soldering fumes and
particlesfromuxinthesolderisdetrimentaltohealth.
• Becareful!Hotsolderingironscancausesevereburnsandignite
res.Donottouchthetiporletitcomeincontactwithanyother 
material.
• Donottouchthetipofahotsolderingironorremovesolderfrom
its surfacewith your hands.
• Ifthesuppliedcableisdamaged,itshouldberepairedbythe
manufactureroritsagentorasuitablequaliedpersoninorderto
avoid a hazard.
• Neverholdthesolderingtiptothesolderingpointtoolong.This
can destroythe soldering point.
• Neveroperatethesolderingironwithoutthesolderingtip.This
can damage the heating device.
• Whenyouarenotusingyoursolderingiron,unplugfromwall
outlet.
• Storethesolderingironinadry,secureplacewherechildren
cannot reach it.
• Keepthesolderingironawayfromdustanddirt,andcleanitwith
a damp cloth occasionallyto keep it looking new.
• 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).
Replacing the Soldering Tip
Your soldering ironcomes with a nickel-plated tip. When
it wears out, youcan replace it with another iron tip (not
supplied).
Unplug the soldering iron’s power cord from the power
source and let it cooldown before replacing the tip.
