OPERATION

TIP & TEMPERATURE SELECTION
TIP OFFSET
Differences between temperature settings and true tip temperatures are negligible when using Thru-hole, single
point soldering or desoldering tips. With any heating system however, actual tip temperatures can differ greatly
from temperature control settings when using larger SMT soldering tips. This difference is called Tip
Temperature Offset. The PACE "Tip & Temperature Selection System" allows you to select and maintain a True
Tip Temperature for any size and type of tip using the appropriate Tip Offset compensation value. The PACE Tip
& Temperature Selection System allows you to select and maintain a True Tip Temperature for any size and type
of SMT tip.
PACE recommends the use of the Tip & Temperature Selection System Booklet (PACE P/N 5050-0251 included
with your system) as a guide to accurately set and maintain a true tip temperature. Select the appropriate
handpiece chart (in the booklet) for your application; identify the correct tip and Dial/Display setting for the
desired tip temperature. Then set the Variable Temperature Control (Dial/Display setting) for the channel
powering the handpiece to obtain the desired True Tip Temperature.
VARIABLE TEMPERATURE CONTROL
Adjust the Variable Temperature Control(s) to the desired temperature setting.
Notice that the control dial has a Gray scale denoting temperature in °C
(Celsius) and a Yellow scale denoting temperature in °F (Fahrenheit). These
numerical scales denote the set tip temperature times 100 (e.g., "3" on the
Yellow scale is 3 x 100 or 300°C).
CHANNEL LED OPERATION
Figure 10. Adjust Temperature
The Channel LED(s) are a visual indication of Power Output status. Following is an explanation of these status
indicators.
LED Full On - Continuous power is being delivered to the handpiece connected to the associated channel. This
condition is evident when the system is first powered up (handpiece heater cold) or the Variable Temperature
Control is increased.
LED Flashing - Indicates that the set tip temperature (as set on the associated Variable Temperature Control) has
been reached. Power to the handpiece is cycling Off and On to maintain set temperature.
LED Off - No power is being delivered to the handpiece connected to the associated channel. This condition is
evident if the Variable Temperature Control is decreased.
