Sodr-X-Tractor Handpiece

Part Number 6010-0106

Manual Number 5050-0492

Rev. C

The following instructions detail the basic operational guidelines for using the
SX-80 Sodr-X-Tractor handpiece.

Introduction

The SX-80 Sodr-X-Tractor handpiece provides thermally enhanced through-hole
desoldering on extra heavy multilayer assemblies at safer, lower temperatures, even
during continuous use. It features a large, easy to replace solder trap. The SX-80
also provides safe removal of TQFP (Thin Quad FlatPack) and TSOP (Thin Small
Outline Package) surface mount components and continuous removal of old solder
from surface mount lands. Its slim-line, pencil grip design and finger actuated
vacuum switch facilitates ease of use and manipulation in tight places. The SX-80 is
a member of the PACE SensaTemp family of advanced handpieces.

CAUTION

Always return heated handpieces to the appropriate Tip & Tool Stand when not in
use. Failure to do so may cause burns to the operator, equipment or work surfaces
and may be a potential ignition source if combustible materials are nearby. Always
use this handpiece in a well ventilated area to avoid inhalation of fumes created by
solder flux.

NOTE

Always use your SX-80 Sodr-X-Tractor with a clean VisiFilter (See page 6) element.
Otherwise a deterioration in performance or damage to the unit may occur.

Select and enter your desired true operating temperature on your PACE power source.
To save tip life and reduce the possibility of damage, PACE recommends using the
lowest possible tip temperature that will provide rapid yet controllable melt of the
entire solder joint to be extracted. Begin with an operating temperature in the range
of 316°C (600°F) and adjust as necessary.

Handpiece Setup

Handpiece Connection

Connect the handpiece connector plug into one of the Power Receptacles on your
PACE power source in the following manner.

1. Align guide on connector with slot on power
receptacle.

2. Insert connector into power receptacle.

3. Turn the connector housing clockwise to
lock in place.

Air Hose Connection

NOTE

Insure that only one air handpiece is connected to either the Vacuum Port or
Controllable PRESSURE Port at one time. Attachment to both ports
simultaneously will cause a deterioration of performance.

To set up your SX-80 air hose connection, perform the following steps:

1. Air Hose To Handpiece Connection

a) Attach one end of a 137cm (54 inch) length of air hose to the metal

tube in the back of the handpiece.

b) If you have a PACE system incorporating only one handpiece, attach

the air hose to the SX-80 power cable using the supplied Hose Clamps
(P/N 1321-0085-01). Space them evenly along the length of the power
cable starting at a point 6 inches from the ends of the handpiece.

c) If you have a PACE system incorporating 2 or more air handpieces

(e.g., SX-80, DTP-80, TJ-70, TP-65), you may wish to leave the air hose
assembly unattached to allow a quick change to any air handpiece
being used.

2. Prepare a VisiFilter (P/N 1309-0028) in the following manner:

a) Connect a 1 inch (2.5cm) length of clear

pvc air hose to the FLOW OUT side of
the VisiFilter; push and turn the hose
onto the VisiFilter nipple to seat.

b) Insert the ribbed end of a male quick

connect hose mount fitting (P/N 1259-

0087) into the free end of the 1 inch
(2.5cm) length of air hose connected to
the FLOW OUT side of the VisiFilter.

c) Connect the free end of the 137cm (54

inch) length of air hose to the FLOW
IN side of the VisiFilter.

d) Insert the end of the quick connect

hose mount fitting (on VisiFilter FLOW
OUT side) into the power source
Vacuum Port.

3. When using air pressure, and/or utilizing multiple air handpieces, PACE
recommends the use of the following set up procedure which utilizes
additional quick connect hose mount fittings. An assortment of quick
connect air fittings are supplied with each additional air handpiece.

a) Disconnect the 137cm (54 inch) length of air hose from the FLOW IN

side of the VisiFilter assembly. Insert the ribbed end of a male quick
connect hose mount fitting (P/N 1259-0087) into the free end of this air
hose.

b) Connect the free end of a 1 inch (2.5cm) length of air hose with an

installed female quick connect hose mount fitting (P/N 1259-0086) to
the FLOW IN side of the VisiFilter Assembly.

c) The 137cm (54 inch) length of air hose can now be easily moved

between the VisiFilter Assembly and the Controllable Pressure Port.
The VisiFilter assembly remains connected to the Vacuum Port.

4. Additional fittings may also be added to the hose connection at the rear of
each air handpiece to ease changing of handpieces.

NOTE

When removing any air hose, turn and pull. Do not attempt to pull hose directly off.
Damage to or breakage of fitting or VisiFilter may occur. Use your SX-80 Sodr-X­Tractor with a clean VisiFilter element. Otherwise a deterioration in performance or
damage to the unit may occur.

Tip Selection

SX-80 Sodr-X-Tractor Tips come in three basic types:

1. Endura Desoldering Tips - These tips are tinnable and provide enhanced
thermal performance for thru-hole desoldering on high mass boards.

2. Endura Pik-Tips - Provides safe removal of TQFP (Thin Quad FlatPack)
and TSOP (Thin Small Outline Package) surface mount components.

3. Endura Flo-D-Sodr Tips - These tips provide rapid, continuous extraction
of old or excess solder from SMT lands.

Size selection of tips is important. For thru-hole desoldering, select a tip with an I.D.
just large enough to allow the lead to freely pass inside. The tip O.D. should not
exceed the diameter of the land to minimize risk of damage to the board substrate.
When removing TQFPs or TSOPs, the Pik-Tip should be sized so that the tip blades
make proper contact with all the lead/land connections simultaneously.

NOTE

The SX-80 Sodr-X-Tractor will only use the new Endura line of desoldering tips.

Tip Installation

For maximum productivity and proper fit, install tips into your SX-80 Sodr-X-Tractor
when the heater is hot and the Flux/Sodr trap and door are installed.

CAUTION

Hold the handpiece with the heater pointed at an
angle up to prevent injury to personnel.

1. Insert the Tip fully into heater bore using
supplied Tip Tool.

2. Gently tighten the Heater Set Screw.

3. Recheck the Heater Set Screw periodically to insure that it remains snug.

NOTE

Periodically, clean the heater bore with a properly sized wire brush (3/16" O.D.) to
insure optimum heat transfer and proper tip grounding.

Temperature Setting

To save tip life and reduce the possibility of damage to the PCB, PACE recommends
using the lowest possible tip temperature that will provide rapid yet controllable melt
of the entire solder joint. Begin with an operating temperature of 316°C (600°F) and
adjust as necessary. Tip temperatures in excess of 399°C (750°F) may cause damage.
For safest removal, some components on extra heavy assemblies may require
preheating or auxiliary heating.

Tip Cleaning

During heavy, continuous desoldering, on boards with flux residues or other
contamination, the tip may occasionally become clogged with such material. If
this should occur, clean the tip with the Tip Cleaning Kit (PACE part number
6993-0200) by inserting the wire tool into the tip end.

Replacing the Disposable Flux/Sodr Trap

As the Sodr-X-Tractor is used, solder and flux build-up will begin to impede the
airflow and decrease system performance. The SX-80 utilizes a disposable chamber
which makes maintenance of the SX-80 a quick and simple process. Regular
replacement of the Sodr-Flux Trap will keep the Sodr-X-Tractor operating at peak
performance. To replace the Sodr-Flux Trap follow the procedures outlined below.

1) While holding the Sodr-X-Tractor with the tip facing away from you and the
handpiece in an downward
position, remove the door
assembly from the handpiece.
This action is accomplished by
pulling the plunger lock
approximately ¼” and turning it
approximately ten (10) degrees to
the right or left. The door
assembly can now be removed by
simply gripping the door near the
ear shaped protrusions and lifting
straight up.

2) Replace the disposable chamber by holding the door assembly in the palm of
your hand with the filter assembly facing up. With your free hand use a fresh
solder chamber with the arrows facing away to push the spent chamber out of
the door assembly and into a waste receptacle. The fresh chamber is now in
position and ready for reassembly.

CAUTION

The handpiece will not function properly if the chamber is inserted incorrectly. The
directional arrows on the solder chamber must be pointed at the heater.

3) Complete the process by lowering the door into the handle assembly. Insure that
the door is properly situated with the ears seated in their respective detents.
Now return the plunger assembly to its locked position by simply twisting the
plunger lock mechanism so that it returns to the channels in the handle assembly.

4) Insure that the door assembly is securely in place by attempting to lift the door
from the handle assembly. It should now be held firmly in place.

5) Check all air hose fittings. Actuate the vacuum and insure that proper vacuum is

present at the tip.

6) Return the handpiece to the cubby or resume work as required.
