PRODUCT DESCRIPTION 136,
136ESD, 137ESD The electronically temperature
controlled soldering station was developed to meet the present and future needs
of the electronic production industry. The many features of the Xytronic
product make it the ideal tool for both service and repair as well as
production line soldering operations. Tip temperature is maintained to
within ±3ºC (±6ºF) of any setting from 150-450ºC (300-850ºF) by an electronic
circuit which has a temperature sensor located at the end of the heating
element. The variable temperature design means no tip or the heating element
changes are necessary to adjust temperatures. Analog stations include a linear-scale meter which indicates the
current tip temperature. LEDs indicator lights are used to signal Power “On” (Green) and Heater “On” (Red). Digital stations include a 14.2 mm
(.560”) three digit LED display to accurately indicate the current tip
temperature directly with a tolerance of ±1ºC (1ºF and one red 5mm LED to
indicate heater “ON”. Non-Display stations include a
multi-color LED to indicate power “On” (Green) or Heater “On” (Red). This soldering station
incorporated a temperature lock to prevent unwanted temperature adjustments by
the operator. Lock in the selected temperature by an allen head screw located
on the front panel. An allen key for this purpose is included. - Feature for the 136, 136ESD,
& 137ESD, is a calibration port located on_the face of the
unit that allows for quick and convenient fine tuning of the electronic temperature
control system. The detachable soldering iron is
connected to the base unit by a fire-resistant silicone rubber cable fitted
with a heavy duty, 5 or 6 pin plug and a steel locking ring. All housings are
molded of tough, heat resistant PC resin to better withstand high impact bumps
and abrasions. All materials used comply with DOD, CE, and MIL Specs. Caution: The heating element for
soldering iron assembly (SIA6O), is made of wound nichrome with a “K” type
thermocouple sensor and comes standard on Xytronic Model numbers 168-30,
XY9-60A, XY9-60D, XY9-60A/ESD, & XY9-600/ESD. Our newest ergonomic mini
handle irons (PIN#107, 1O7ESD)
incorporate a long life Japanese made ceramic heater with PTC sensor and is
standard equipment on Xytronic model numbers 136, 136ESD & 137ESD. The two
types of iron assemblies are incompatible and use of the wrong type of iron can
lead to premature heating element failure. The 5 pin configuration of the SIA6O
can be easily distinguished from the 6 pin connector of the 107 (1O7ESD) iron.
Please refer to Figures 1 & 2. The power unit is isolated form
the AC line by a high efficiency 24VAC output transformer for user safety and
to prevent unwanted high voltage leakage that may damage current sensitive
components. Zero-voltage switching circuit is incorporated to protect the C-MOS
IC from damage by transient voltage spikes. Fig. 2 SOLDERING IRON ASSY 107/107 ESD
A low temperature will slow the
rate of flow of the solder. A high temperature will burn the flux in the
solder, which in turn will emit a heavy white smoke resulting in a dry joint or
damage to the P.C.B. When the iron is set to the
correct temperature for the particular soldering situation at hand, a good
joint is assured. Key to successful soldering is knowing the type of solder you
are using, the size of the joint to be soldered and the characteristic of the
p.c.b. & component used and adjusting the tip temperature to meet the needs
of the application. The most common solder alloy used
in the electronic industry is 60% tin, 40% lead (60/40). The tip working
temperature of the solder is detailed below and can vary from manufacturer to
manufacturer. Below are listed the common
temperature for the specific job. SOLDERING

OPERATING INSTRUCTIONS * Ensure that the working
voltage matches your power supply before plugging in the station. * Check carefully for any
damage during transportation. Analog
Stations—linear analog meter, Model: 168-3C, XY9-60A, & XY9-60A/ESD. Set
temperature by rotating temperature control knob on the front of the front
panel stopping at the desired temperature. Digital
Stations—digital display, Model: XY9-60D, & XY9-60D/ESD & 137ESD Set
temperature by moving “SET-READ” switch to “SET” position, rotate temperature
control knob until the digital display reads the desired temperature, then move
“SET-READ” switch to “READ” position. The station will then maintain the
pre-set temperature No Digital
Stations — Model:

temperature by rotating temperature control knob on the front of the front
panel. First Time
Use: 1. Ensure
that the base unit’s power switch is in the “OFF” position. 2. Set
the temperature control knob to the MIN setting. 3. Switch
the base unit power switch to the “ON” position. Note that the LED light will
turn off when the tool reaches the set temperature. Models 136 & 136ESD use
a multi-color LED to indicate that the iron has reached the desired
temperature by changing from green to orange in color. 4. Rotate
the temperature control knob to 250ºC (480ºF), waiting until the LED turns off
to begin liberally tinning the soldering tip with a protective layer of solder. 5. Adjust
the temperature to the desired setting. When the LED turns off (or changes
color) you are ready to begin. CAUTION: Soldering
irons operate at high temperatures and can easily burn people or objects. Do not touch the tip and
heater at any time while the unit is on and keep it a sate distance from
inflammable materials. Please allow sufficient time for it to cool before
changing tips or servicing the unit! COMMON
CAUSES OF TIP UNWETTING 1. Tip
temperature higher than 410ºC (770ºF) 2. The
tip working surfaces are not tinned while the iron idling. 3. Lack
of flux in soldering, wicking, repairing, and touch-up operations. 4. Wiping
the tip on a high sulfur content, dirty or dry sponges and rags. 5. Touching
with organic substances such as plastic, resin, silicone, grease and other
chemicals. 6. Impurities
in solder and/or low tin content.
CARE OF
TIPS Caution : The
solder iron can reach very high temperatures. Be sure to turn the unit off
prior to carrying out any maintenance or trouble shooting steps listed below! IMPORTANT Remove
the tip and clean after moderate to heavy use or at least daily if on the production
line. Remove any loose build up in the tip retaining assembly to prevent tip
freezing. The
solder tips supplied are iron clad copper and if used properly, they should
maintain optimum life. 1. Always
tin the tip before returning it to the holder, turning off the station, or
storing it for long periods of time. Wipe the tip on a wet sponge prior to use. 2. Keeping
the iron set at high temperatures (more than 400ºC or 750ºF) will shorten tip
life. 3. Do
not use excessive pressure on the tip or rub the joint with the tip while
soldering, it does not improve the heat transfer and may damage the tip. 4. Apply
solder to the joint, not the tip when soldering. The flux is naturally caustic
and thus will eat away the tip. 5. Never
clean the tip with a file or abrasive materials. 6. Do
not use fluxes which contain chloride or acid. Use only rosin or resin
activated fluxes. 7. It
an oxide film forms on the tip, it can be removed by careful buffing with a
600-800 grit emery cloth, isopropyl alcohol or equivalent and then wrapping
rosin core solder around the newly exposed surfaces Coat the tinned areas with
rosin-core solder after the resin-core has melted NEW TIPS Following
these steps will lead to optimum tip life 1. Set
temperature to min. then turn the main power switch to the “ON” position. 2. Set
temperature to 250ºC (482ºF). 3. Coat
the tinned surfaces with rosin-core solder after reaching 250ºC (482ºF). 4. Set
to desired temperature after allowing the unit to idle at 250”C for 3 minutes. 5. The
iron will be ready for use once it reaches the preset temperature. IMPORTANT: Remove and
clean the tip daily. If a new tip is installed, remove any loose build up in
the barrel assembly otherwise the tip may fuse to the heating element or
retaining barrel. MAINTENANCE TIP MAINTENANCE AND DRESSING
Tips
can be changed or replaced simply by unscrewing the knurled nut barrel
assembly. The station must be switched off and allowed to cool before
this operation as damage may result if the system is left on without the tip in
place! After removing the tip, blow out any oxide dust that may
have formed in the tip retaining area of the barrel. Be careful to avoid
getting this dust in your eyes. Replace the tip and screw back the knurled nut
barrel assembly using only firm hand pressure to tighten. Pliers should only
be used to tighten the nut to avoid burning your fingers, but care should be
taken not to over-tighten as this could damage the element. GENERAL CLEANING The outer cover of the iron and station may be cleaned with
a damp cloth using small amounts of liquid detergent. Never submerse the unit
in liquid or allow any liquid to enter the case of the station. Never use any
solvent to clean the case. SERVICE If the iron or station should become faulty or, for some
reason not operate normally, the system should be returned to the service
department of your authorized dealer or agent. WARNING: Keep out of the reach of children. WARNING: Do not inhale solder fumes. WARNING: Keep tip and
heating element away from the body, clothes and flammable material when in
operation
