GLOSSARY
Arc Established — A signal generated by the power
source indicating that an arc is struck from the wire to
the work.
Arc Hours — Amount of time that the control panel has
been in control of an arc, i.e., the accumulated amount of
weld time on the panel.
Automatic Configuration — This is the configuration
where the weld is controlled entirely by the welding
equipment.
CV — constant voltage power source.
Deadman Operation — This mode of operation requires
that the control signal to start an event is required
throughout the whole event or that event will be
terminated.
Fault — A condition where an operation normally under
control of the panel is not operating correctly. Faults can
be Ground, Feeder, or Tolerance Faults. See Operational
Faults section located in the Operation chapter.
Fault Abort — The control panel will terminate the weld
by proceeding to the crater fill segment when a tolerance
fault is recognized by the control panel (see Fault Delay
Time) and the fault abort is enabled. See Soft Switch
section located in the Operation chapter.
Fault Delay Time — The amount of time that a tolerance
fault condition must continuously exist before the control
panel recognizes the error. This time is default set to 1
second, or programmable. See Soft Switch section located
in the Operation chapter.
Feeder Fault — This occurs if the current through the
motor exceeds specifications. This could be from a bind
on the feed, bad cabling or various other causes. This
fault will disable the motor control circuitry. In order to
clear the error, power should be cycled on the control
panel.
Ground Fault — The ground fault occurs when a large
current is sensed through the earth ground from the
power source to the HMC-410 chassis. This fault will
cause the control panel to shut down all systems under
its control since it is a significant safety hazard.
Maximum Programmable Voltage — This voltage is the
maximum number that can be programmed in the center
display for the run-in, weld, crater fill, and burnback
segments. This number changes depending on the type
of power source that is used.
The following table shows the various maximums:
RC/RCC 300 36 V
RC/RCC 450 42 V
RC/RCC 650 44 V
Arc-Master 501 40 V (44 V Pulsed MIG)
Arc-Master 351 38 V (44 V Pulsed MIG)
Fabstar 4030 36 V
Excel-Arc 4030 36 V
Excel-Arc 6045 42 V
Excel-Arc 8065 44 V
Ultra Flex CC/CV 38 V (44 V Pulsed MIG)
Ultra Flex Pulse 38 V (44 V Pulsed MIG)
Minimum Programmable Voltage — This voltage is the
minimum number that can be programmed in the center
display for the run-in, weld, crater fill, and burnback
segments. This number changes depending on the type
of power source that is used. The following table shows
the various minimums:
RC/RCC 300 10 V
RC/RCC 450 10 V
RC/RCC 650 10 V
Arc-Master 500 10 V (0 V Pulsed MIG)
Arc-Master 350 10 V (0 V Pulsed MIG)
Fabstar 4030 10 V
Excel-Arc 4030 11 V
Excel-Arc 6045 12 V
Excel-Arc 8065 14 V
Ultra Flex CC/CV 10 V (0 V Pulsed MIG)
Ultra Flex Pulse 10 V (0 V Pulsed MIG)
