CHAPTER 1: DESCRIPTION
HF28 DC RESISTANCE WELDING SYSTEM
990-372 1-7
Control Mode Selection Keys. These keys allow you to select the control mode when
programming with the
WELD
(time/energy) selector keys.
Pressing the
kA
key selects current as the control mode for this schedule. The
control will output the current waveform shown on the LCD.
Pressing the
V
key selects voltage as the control mode for this schedule. The
control will output the voltage waveform shown on the LCD.
NOTE: Selecting the voltage feedback mode requires you to make a test weld
when the voltage or weld pulse time is changed. The test weld optimizes the
Control feedback performance. The weld status message
TEST
disappears after
the internal control parameters are optimized.
Pressing the
kW
key selects power as the control mode for this schedule. The
control will output the power waveform shown on the LCD.
Monitor Keys
These keys allow you to view the results of the last weld and to set the limits of the welding parameters
beyond which the energy limits monitor terminate the weld and/or initiate alarms.
Pressing the
kA
key displays the current monitor. This screen shows the results of
the most recent weld. This screen also allows the operator to set limits that
automatically interrupt the weld when they are reached. You can also program
the current monitor to output an alarm when the limits are exceeded.
Pressing the
V
key displays the voltage monitor. This screen shows the results of
the most recent weld. This screen also allows the operator to set limits that
automatically interrupt the weld when they are reached. You can also program
the voltage monitor to output an alarm when the limits are exceeded.
