CHAPTER 1: DESCRIPTION
HF28 DC RESISTANCE WELDING SYSTEM
1-8 990-372
Pressing the
kW
key displays the power 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 power monitor to output an alarm when the limits are exceeded.
Pressing the
Ω
key displays the resistance 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 power monitor to output an alarm when the limits are exceeded.
Pressing this key selects either peak welding energy or average welding energy to
be monitored by the energy limits monitors.
WELD/NO WELD Switch
When the switch is in the
WELD
position, the programmed weld sequence can
initiate weld energy.
When you set this switch to the
NO WELD
position, no weld current can flow.
However, the Control can execute a complete weld sequence. This function is
required to adjust the weld head prior to operation.
Emergency Stop Switch Operation
If your work station is equipped with an emergency stop switch (connected to the emergency stop
connection of the Control), operate the switch to immediately stop the welding process. All power to
the air valves and power circuits will be disconnected. To restart the Control, you must press the
RUN
key on the front panel.
