Vacuum/Pressure Pump Operation
The PACE ST125 contains a vacuum pump that also provides air pressure. To activate, depress the activation button on
the connected handpiece. The ST125 has an optional foot pedal connector on the back, which can be used to activate
the pump instead of the switch on the handpiece.
Tip Offset
Differences between the temperature settings and true tip temperatures are negligible when using Thru-Hole,
single point soldering tips. With any heating system however, True Tip Temperatures can differ greatly from
temperature settings when using larger SMT soldering tips. Before adjusting offset, it is recommended to first
check the actual temperature of the tip using a Tip Temperature Monitor.
To adjust the temperature offset, hold the Program Key ( ) down for 5 seconds. The display will change to
show "000". If the unit already has a Tip Offset than it will be shown in place of "000". Use the keypad (
increase the temperature offset up to 83°C (150°F) hotter. When finished press the Program Key ( ) to return
to normal operation or, after 5 seconds of inactivity, the system will return to normal operation on its own
