Operation

Temperature Selection

Variable Temperature Control

Adjust the Variable Temperature Control Knob
to the desired temperature setting. Notice that
the control dial has a White graphic scale
denoting temperature in °C (Celsius) and a
Yellow graphic scale denoting temperature in
°F (Fahrenheit). These numerical scales
denote the set tip temperature times 100 (e.g.,
"3" on the White scale is 3 x 100 or 300°C).
Temperature/Dial Lock
The Variable Temperature Control Knob can
be locked in position (at one temperature) to
avoid accidental or unauthorized changes of
the temperature setting. Perform the following
procedure to lock the Variable Temperature
Control Knob.
1. Adjust the Temp. Control Knob to the
desired temperature setting.
2. Using the Temp. Locking Key (hex
head wrench) included with the system,
tighten the 2 set screws on the Temp.
Locking Ring.
NOTE - Temperature will remain at its locked setting, even if the Variable
Temperature Control Knob is forced to move.

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. This difference is called Tip Temperature Offset.
PACE recommends the use of the Tip & Temperature Selection System booklet
(PACE P/N 5050-0251) as a guide to accurately set and maintain a true tip
temperature for any size and type of SMT tip.
