CHAPTER 3: SYSTEM CONFIGURATION
HF28 DC RESISTANCE WELDING SYSTEM
3-14 990-372
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.
In the example on the right, the top line of the
screen shows that the Control is in the
RUN
state,
the voltage at the voltage sense lead connections
for the
PULSE 1
weld period was
1.012
volts, the
monitor is set for displaying peak voltage (rather
than average voltage), the voltage at the voltage
sense input
connection for the
PULSE 2
weld period was
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
1
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 in milliseconds.
See Chapter 5, Operating Instructions for application-related descriptions of the weld schedule profile.
