CHAPTER 3: USING PROGRAMMING FUNCTIONS
HF25 DC RESISTANCE WELDING SYSTEM

Run State
Pressing the
RUN
key puts the Control in the run
state. In the run state, the screen shows a trace
that represents your programmed parameters for
a given weld schedule. You may select a
different weld schedule to be programmed with
the
SCHEDULE
key and keypad, or with the up
and down arrows. Then, you may program
squeeze time, up slope, weld time, weld energy,
down slope and cool time with the trace segment selector keys.
The top line of text is showing (in the order displayed) that the Control is in the run state, the voltage at
the voltage sense lead connections for the
PULSE 1
weld period is
1.012
volts, the energy limits monitor
is set for monitoring peak voltage (rather than average voltage), the voltage at the voltage sense input
connection for the
PULSE 2
weld period is
1.014
volts, and the total weld count since the weld counter
was last reset is
5,237
.
The weld profile trace is an analog display of the
electrical parameters programmed with the weld
period selector keys. When the weld is initiated,
a profile of the actual weld energy delivered
during the weld cycle, or both weld cycles, will
be overlaid on the trace.
The large-type number
02
is the selected weld
schedule.
The values
0.050kA
and
0.060kA
below the trace are respectively the weld current values programmed
for
PULSE 1
and
PULSE 2
weld periods. You may optionally program weld energy in volts or kilowatts
with the energy units selection keys.
Use the time/energy selector keys to toggle between the weld energy value field and the bottom line of
text, which is the weld period time selection field. Use the weld period selector keys to enable the weld
periods for programming, and use the numeric pad keys for entering time values.
See
Section IV, Using HF28 Welding and Monitoring Functions for application-related descriptions of
the weld schedule profile.
