2,0 Description
All soldering applications require the introduction ofenough heatto activate the t'lux and t'lou the solder.
Whenever tools that are being used ttr pertbrm a soldering application take too long to achieve the required
process temperature, tle potential tirr thermal damage exists. Resistance Soldering Equipment gives a user
the ability to manufacture an intense level of heat that can be regulated and localized rvithin the intended
solder joint in a more efficient manner lhan most other available methods. This means a faster soldering
process and less time for dissipative heat to cause any thermal damage to the components that are being
soldered or any materials or components that may be within the immediate area sunounding the intended
Resistance Soldering is accomplished bl producing a safe (lorv-voltagerhigh-amperage) AC current which
is then passed through special electrc.des (manufactured out ofhigh resistance metal allols or other resistive
materials) to generate an intense level of available heat. A closed loop circuit is required so that the current
can be passed from one resistive electrode directly through the base metals that are being soldered and into
the other electrode back to the po*er unit. An isolated transformer is used so that the current does not stra]
or leak into unwanted areas. but talies the most direct path from one electrode to the other rvhich completes
the circuit that is required to generate the desired heat. The resistance ofthe special electrodes that are used
creates the majoriqv ofthe heat that is being generated. Anl additional resistance rhat exists at the point of
contact and within the base metals that are being soldered will increase the amounl of available heat that can
be generated within the solderjoint. 81'regulating the output voltage olthe resistance soldering power unit
the heat that is generated can be adjusted to the specific level required tbr the soldering application that is
being performed.

2.1 The Science of Electricity
Resistance heat can be developed because ofthe three fundamental forces that control all electrical circuitsl
vol tage. amperage, and resistance.
Its scientific name is electromotive lorce lvhich is usually represented in formulas with a capital letter ''E".
The electromotive tbrce or electrical pressure that moves an electrical cunent through a conductive material
is measured in units that are called volts. One lolt is equal to the amount ofelectromotive force necessary to
force one ampere ofcurrent to flou through a resistance ofone ohm. Generally a higher voltage means that
more current will flow and a louer voltage means that less cunent will tlos through an electrical circuit.
he used lo measure the amount ofvoltage (electrical pressure)
A voltmetet can

The scientific reference is intensitl Lrlcurrent flow usually represented in formulas with a capital letter "I".
The rate at which an electrical cunent u ill l'lorv through a conductive material can be measured in units that
are called amperes. One ampere equals a tlon of6.25 x 1023 electrons (called one coulomb) per second.
Using the water flowing through a pipe analogl to describe the way that current florvs along a conductor,
current rvill flow more readill through a short thick conductor than through a long nanorv conductor.

Resistance is the property ofa material which resists or opposes the flow ofan electrical cunent through it.
The actual resistance (R) of a material is dependant upon its resistivity (p) which can be different for each
nraterial, along with its physical characteristics tsuch as the materials overall length and cross-sectional
This can generally be shown as R: pLlA, rvhere R is the resistance in Q (ohms). p is the known resistivity
of the conductive material, L is the length ofthe conductor and A the cross sectional area ofthe conductor.
Resistivity (p): is unique to each material being soldered.
Length (L): A greater length increases the amount of resistance and a shorter lengh decreases resistance.
Area (A): A greater area decreases the amount of resisrance and a smaller area increases the resistance.

Resistance Heat
Resistance heat is the heat that is developed as an electrical cunent is passed through a conductive material
because ofthat conductive material's resistance (or opposirirrn) to the cunent that is being passed through it.
Whenever an electrical cunent (l) flows through a conductive material with resistance (R), electrical energ;is converted to heat at a rate ofpower (P) that may be calculated as P: I? R, where P is the polver measured
in watts, I is the cunent measured in amperes and R is the resistance measured in O lohms).
The heating eflect of resistance is often considered undesirable in the transmission of current tbr most
electrical applications and must be minimized, but it is verl useful tbr intentionally generating electrical
heat tbr a variety of uses, in this case Resistance Soldering. Understanding that some materials have a
higher level ofresistivity than others and that the actual amount ofresistance can be altered by changing the
physical characteristics of the material is an important part ol us creating and utilizing resistance heat tbr
various soldering applications.

Basic System ConJigaration
When configuring the basic resistance soldering system that will be required for any applicatior
your three primary components will be a handpiece. a power unit and a footswitch. There are a wid
variety of American BeautyD resistance soldering handpieces and several power units available to choos
from along with various accessories rvhich migtrr ais,. be recommended or required for more specialize
applications. It is important to properl] match the handpiece and power unit to the intended solderin
applications when configuring a s-vstem. in order tt be .rble to marimize the full range of benefits that ca
be obtained with the use of resistance soldering equrFment. You should determine the most appropriat
handpiece to use for the application first and then rq.g srll be better able to decide on the power unii th:
will give you the w-idestpossible working range and rersatility. Ifyou are considering using resistanc
soldering equipment for more than one applicatitrn. ) ou rna) find it beneficial to evaluate the requiremenl
of the largest application first. This approach can decre.::e ]our total cost of ownership by purchasing
single power unit to work in conjunction with multiple h.rndpieces.
5.1 Choosing the Correct Handpiece

process that is being developed along with the size. shape and tlpe ofthe materials that are being solderec
The handpiece style that is being chosen for a specific apphcarron should allow for proper placement ofth
electrodes to the work based on the accessibility to the srrlder_roint area along with any special horizontal c

5.2 Handpiece
3eri !
The handpiece styles that are currently available include single electrode (used rvith a lead for current
return) dual electrode stationary, dual electrode tweezers, dual electrode pliers. dual electrode forks and a
variety of handpieces designed especialll for thermal wire stripping. All of the handpiece styles that are
listed here are available in a varietv of sizes in order to best meet the specific application requirements that
might exist.
Single Electrode Handpieces give -vou the ability to direct the heat to a specific point of contact in the
same manner as you would with a conventional soldering iron but with a much higher thermal capaciry
available. Using a lead for cunent retum will be necessary with the use of this st1{e of handpiece in order
to complete the required current path. The most appropriate handpiece size to choose is directll related tt
the electrode that will work best for the application that is being considered. Choose the ele.'trode :ize ;n ihc
same manner as you would when choosing a soldering iron tip size. Match the electrode diameler l.' :he
area being soldered.
Stationary Dual Electrode Handpieces sere initially developed for the highl."- repetitile sricer:ng of
similar sized terminations (terminal strips. multiple termination buss bars, etc.). The] ma1 be used on
applications similar to those where single electrode handpieces might be considered but the] do not require
the use of a lead for cunent retum to operate properly. The electrode tips are positioned in :r ;lose proximiry'
to one another and will complete the cunent path b)- passing current through the surface ofthe material that
is to be heated. With minor adjustments or modit'ications to the electrodes (bending. grinding. etc.) they can
be positioned in a manner appropriate to the requirements ofthe application that the] are intended fbr.
Tweezer Style Dual Electrode Handpieces will allow you to direct the heat ttr a specific area while
actually holding the component in place during a soldering application. After florving the solder .v-ou can
deactivate the footswitch while continuing to hold the component in place to cool. This helps to eliminate
cold solder joints that might be caused by agitation of the joint while it is cooling. The metal electrodes
being used in these handpieces can be bent to improve the ergonomic teel of rhe handpiece and the
electrode tips can be contoured to custom fit the work surface improving the thermal ransfer tiom the
electrodes into the work.
Pliers St-vle Dual Electrode Handpieces are similar in design to tweezer s4le handpieces but
developed for heavier applications and can obtain much higher operating temperatures. These handpieces
incorporate carbon block electrtrdes that allorv you to operate at temperature levels shich could actually
melt the metal allol electrrrdes rhat are used in the tweezer style handpieces. Carbon block electrodes have
increased lrork surtbces and can be contoured to increase the surface contact area of the electrodes to the
work even further. Ths inerea-ied crrntact area will greatly improve the thermal transfer that talies place
during soldering. _ .
Fork Style Dual Electrode Handpieces are similar in design to the largest
heav-v-dutv pliers-stvle
handpieces. These handpieces incLrrporate an entirely different type of adapter and electrode configuration
allowing for an increased level of versatilit-v. Because the electrodes are rods and the adapters can be
swiveled for more specific orientation of the electrode tips to the required surface area of the work many
applications may be performed nith an increased level ofefficiency and control.
Thermal Wirestripping Handpieces have been developed primarily for the purpose of thermally stripping
the insulation from wires to help minimize the hazard of nicking scoring or othenvise damaging the
conductors. These handpieces have closed loop elements which will begin to heat as soon as the power unit
is activated. The output ofthe ptser unit should be adjusted only high enough to allot the elements ofthe
handpiece to reach the temperarure required for melting through the insulation $ ithout buming it. The nvo
basic types ofthermal uirestripping handpieces that are cunently manufactured are the nveezer st-vle and
the V-notch style. The trveezer srlle handpieces are designed for stripping smaller gauge wires and the Vnotch style are designed for stripping the larger gauge wires.
Soller Reflow Tools

7.0 Developing I'our Soldering Process

process. Devellrptng the srlJenng prlrcess using resistance soldering equipment is quite simple and rvill be
ver) eas) to mliter. i'n.. \.'u rulh understand the basic principles ofelectriciq that are involved in the
development r.ircts.ten;rlrai lJtrs manual should answer the majoritl of lour questions and get.vou on
the right track.
All ofthe American Beaun r
resistance soldering power units have a specialll developed transformer that
converts your standard I l0-110 \'.{C input line voltage into a completell safe (lo$ voltage,rhigh amperage)
AC electrical cunent. When this sate. l!r$' voltage current gets passed through a resistive material an intense
amount of heat can be developed u ithin the immediate area of resistance. This immediate area of resistance
exists within the intended solderjoint area ofthe base materials located benveen rhe tips ofthe electrodes.
Resistive heat will be developed because of the resistance that an electrical current encounters when being
passed through the electrodes and the base metals. A closed circuit is required in order to maintain the path
for proper current flo* . The am.runt of heat produced is determined b;- the output current being supplied b-uthe power unit. It is imponanl tlr determine the output current that is required to produce the correct level of
heat for the process that is beine developed. Your primary goal should be lo establish the shortest dwell
time in which you can comtirnabl)' create good qualitv solder joints. In the beginning this must be
accomplished by trial and error. houever as you become more accustomed to the resistance soldering
equipment you rrill become bener able to predict the required du'ell times and the most efficient output
settings with a far greater level of accuracy and consistency.

Quality Soldering Tools
In the beginning stages ofyour nel\'process derelopment it is often very beneficial for
-vou to use dummy
components or scrap pieces of similar size and material to the ach-al components that you will be soldering.
This should help you to establish the most elficient porver unit output to be used without causing unwanted
damage to any expensive materials or compLrnents during the initial process development stages.
Whenever a soldering application involves joining togethei pieces ofvastly different sizes, or components
that mav be highl-"" sensitive to thermal damage. ]ou may want to consider pre-tinning the pieces separately
and then joining them together by re-flowing the solder and adding enough new solder to complete the joint.
7.1 Daermining Appropriote Power Levels
Establish a good contact with the base materials (close to the intended solderjoint area) and both electrodes
(or the single electrode and retum hamess clip) and activate the footswitch. Apply solder to thejoint area as
it is heating, then release the tbotssitch once the solder has properly flowed. Because there is no longer any
current being supplied to the handpie.'e. 1ou will be able to hold the components in place while allowing the
solderjoint to cool undisturbed until the solder has finished setting.
Upon completion of the first solder joint l ou should be able to evaluate the results that have been achieved.
Based upon this evaluation 1ou should be able to determine whetier there are any adjustments that might be
recommended or even required to improve the soldering process. You should be especially concemed about
the amount of dwell time thar is required in order to properly flow the solder. Remember that your goal is
to estalrlish the shortest dnell time
solder joint.
in which )'ou can comfortably and efficientlv create a quality
If the output of the power unit is set too high \Lru ian prlrduce dt'ell times so shon that lou will have little
or no measure ofcontrollability. Dtell times that nlie iess than one second are generalll:not recommended
without the use of a precision timer unit. Ilthe dlell time is too short and a precision timer unit is not going
to be used you should adjust the ouput olthe po\\er unit to a lower level (this will increase the dwell time
and improve the level ofprocess controllabilin r and rhen attempt the soldering process again.
Ifthe output ofthe power unit is set too los ltu .an Fr!)duce dwell times that are too long which increases
the time available for heat to travel a\\'a] tiom the st'iJer joint and into unwanted areas. Longer dwell times
increases the chances of causing damage to thermalll sensitive components or materials that are being used.
lfthe dwell time is longer than necessary'1ou should increase the output ofthe porver unit to a higher level
(this decreases dwell time and the possibilitv ofthermal damage) and attempt the soldering process again.
7.2 Maximum Operating PAiameterc
All ofthe resistance sotieting power units have a recomniended 50% duty-cycle. What this means is rhat
a power unit is being operated at levels above 50?ir oftheir r.rml available output power the dwell (heating)
and idle (cooling) time must be regulated in equal measure. It is important for the idle (cooling) time to be
equal to, or greater than the dwell (heating) time that is required for soldering. Ifit takes l0 seconds for the
solder to florv properly you must allow a minimum of l0 seconds of cooting time befbre proceeding to the
next solderjoint. You should also monitor the handpiece cables tbr excessive heat buildup during soldering.
If you find excessive heat building up in the cables 1ou shc.uld funher lengthen the required cooling time.
To prevent darnage to the equipment you must never operate pol\'er units for longer than 20 seconds on any
setting lvhile soldering. Ifyou have reached the marimum available output ofthe power unit and cannot get
the solder to flow within this amount of time you should malie sure there is no problem with the equipment
set-up and then verif good electrical contact between the elecrodes and the base materials or components.
Once you have verified the equipment set-up and the electrical contact the next area for consideration is the
power unit and handpiece configuration you have chosen for the application being attempted. The specific
application that you are trying to perform may require a higher output power unit and a dilTerent handpiece
to achieve the desired results. Although this segment does not apply to thermal rvirestripping applications,
the handpiece cables should still be monitored for excessive thermal buildup.

Ifthe proper AC voltage ca4lnt be terified at each ofthe steps listed below, continue on with the next step
Th_ese are
and have already been able
1. Verifr that the proper.\c
is being conducted into the handpiece's electrodes.
If proper AC voltage is available
at the eleCtrodes but no heat is being developed they may require cleanin5
where they make contact s'ith the'!ate metals. Contamination, dirt and bumt flux may encumber the curren
ilorv that is required from the crrnla!'t suriaces ofthe electrodes and through the base metals.
2. Veril],
that the proper AC voltage is being conducted to the electrode adapters.
Ifproper AC voltage is available rvithin the electrode adapters but unavailable from the electrodes be sure
that their contact surfaces have not become .onlaminated and that the electrodes have not become loosened
lvlalie sure that any set-scJ9ws tbat belong in rhe adapters are still in place and are properly tightened.
3. Verif,thattheproperACvolrageisbeingc.uducredtiomthepouerunit'soutputreceptacles.
tf proper AC voltage is aV$able at the power unit rrutput but is unavailable at the electrodes and adapters
be sure the handpiece is sgiurely connected to the poser unit and check the electrodes and adapters again.
If proper AC voltage is siill unavailable at the elecrrtrdes or the adapters the handpiece may ha-ve devilopec
a short in the cables, or ong ofthe wire conneclirrns mal have become loose. Ifyou are unable to determine
the source ofthe problent you may wish to rerum r..ur handpiece to the factory for an evaluation and repair
4. Verifothattheproporl20VAClinevoltageisarailablefromthereceptacleofthefootswitch'spig$.back plug assembly whgrl thq footsrvitch is beine depressed.
Ifproper line voltage is qvailable from the receptacle ..fthe footswitch's piggy-back plug assembly.but the
proper output is unavallaple from the porver unit. be sure that the power unit is tumed on and rhat the circuil
breaker has not been tripped. Ifthe circuit brealier has nlrr been tripped the problem may exist inside ofthe
power unit and you iiray wish to retum it to the facroq tbr an evaluition and repair.
5. Verifothattheproperl20VAClinevoltageisavailablefromthemainpowersupplyreceptaclethatthe
fbotswitch's piggy-back plug assembly was plugged inro.
If proper 120 VAC line voltage is available from the main porver receptacle but it is unar.ailable liom the
receptacle ofthe footswitch's piggy-back plug assembll )ou ma]'wish to retum vour tbots\ritch assembly
to the factory for an evaluation and repair.
You may find it easier to troubleshoot your resistance soldering system by following the verification steps
that are listed above in the reverse order (similar to the initial set-up procedures) tracing voltage fronr the
source until you reach the point where it becomes unavailable and then determining the exact cause.
