Safety
Safety Guidelines
The following are safety precautions that personnel must understand and follow when using or
servicing this product.
1. POTENTIAL SHOCK HAZARD - Repair procedures on PACE products should be performed
by Qualified Service Personnel only. Line voltage parts may be exposed when the
equipment is disassembled. Service personnel must avoid contact with these parts when
troubleshooting the product.
2. To prevent personnel injury, adhere to safety guidelines in accordance with OSHA and other
applicable safety standards.
3. SensaTemp handpiece heaters and installed tips are hot when the handpiece is powered on
and for a period of time after power off. DO NOT touch either the heater or the tip. Severe
burns may result.
4. PACE Tip & Tool Stands and handpiece cubbies are designed specifically for use with the
associated handpiece and houses it in a manner that protects the user from accidental burns.
Always store the handpiece in its holder. Be sure to place the handpiece in its holder after
use and allow for cooling before storing.
5. Always use PACE systems in a well ventilated area. A fume extraction system such as those
available from PACE are highly recommended to help protect personnel from solder flux
fumes.
6. Exercise proper precautions when using chemicals (e.g., solder paste). Refer to the Material
Safety Data Sheet (MSDS) supplied with each chemical and adhere to all safety precautions
recommended by the manufacturer.

System Set-Up
Set up the ST 145 system using the following steps and associated drawings.
1. Store the shipping container in a convenient location. Reuse of these
containers will prevent damage if you store or ship your system.
2. Place the Power Switch in the “OFF” or “0” position.
Tip & Tool Stand
The Tip & Tool Stand can be mounted to the power source. If the system will be placed on the
workbench, this is recommended. If the ST 145 is to be mounted under the workbench or shelf, the
Tip & Tool Stand should not be mounted to the power source.
1. To attach the stand to the power source:
a) Insert the 2 Mounting Screws (head first) into the
power source mounting slots (plastic case shown).
Slide the screws toward rear of the power source.
b) Place the Tip & Tool Stand beside the power source.
Insert ends of the 2 Mounting Screws into the 2 Tip &
Tool Stand mounting holes as shown.
c) Install a Thumb Nut onto the end of each Mounting
Screw and tighten Thumb Nuts.
2. Place the handpiece into its Tip & Tool Stand.
Handpiece Connection
Connect the handpiece connector plug into the Power Receptacle 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.
CAUTION: Ensure that only one air hose is connected to the
VACUUM or controllable PRESSURE port at one time. Attachment to both ports
simultaneously will cause deterioration in performance.
TEKLINK
The TEKLINK receptacle located on the back panel of the power supply allows
you to interface the VACUUM and PRESSURE features of your ST 125/145
with the SODRTEK ST 25/45 system. This feature gives you the freedom to
operate air-controlled handpieces (SX-70/80, TP-65, or TJ-70/80) from an ST
25/45 system through the VACUUM and PRESSURE ports of your ST
125/145. To link your ST 125/145 system to the ST 25/45 system, perform the
following procedure.
TEKLINK Receptacle

All Rights Reserved

1. Place the ST 25/45 system adjacent to (side by side) or stacked on top of your ST 125/145
system.
2. Use the TEKLINK cable (sold separately) to connect the systems together. The TEKLINK
Receptacle is located on the back panel of each power supply.
3. Ensure the VisiFilter assembly is connected to either the ST 125/145 VACUUM Port.
4. Connect the air hose of the handpiece being used, to either the VisiFilter assembly or the
controllable PRESSURE port.
The TEKLINK Remote Box (sold separately) allows the connection of up to three ST 25/45 systems in
any combination.
NOTE: Systems connected together through the TEKLINK system must be used and controlled by a
single operator. Any attempt to operate by more than one individual can create a hazardous
condition and will cause deterioration in performance.
System Power Up
1. Insert the female end of the power cord into the AC Power Receptacle on the rear panel of
the power source.
2. Plug the prong end (male end) of the power cord into an appropriate 3 wire grounded AC
supply receptacle.
CAUTION: To insure operator and ESD/EOS safety, the AC power supply receptacle must be
checked for proper grounding before initial operation.
