HMC-410
7-2 July 27, 2005
Multi Sub Segment Operation — This type of operation
allows the weld parameters to automatically change during
a weld without stopping and restarting the weld. Refer to
the Operation chapter for more details.
Nonvolatile Memory — This memory will store the
various, long term programmable parameters. Nonvolatile
means that it is not disrupted by power loss.
Ready Mode — The mode in which the control panel
segments can be viewed, and if so privileged,
programmed. The control panel is in ready mode if the
unit is not in a weld cycle, and is not performing
diagnostics.
Schedule — The collection of various segments which
together describe a complete weld.
Semiautomatic Configuration — This configuration is
where the control panel controls the power source and
the feeder, but the welder moves, guides, and directs the
arc on the work. In this configuration, the HMC-410 may
typically be physically placed on a feeder.
Sequence/Weld Sequence — Weld cycle.
Soft Switch — Soft switches allow for setup of
configuration parameters. Refer to the Operation chapter
for more details.
Sub Segment — The weld sub segment(s) are segments
which can be executed while the weld is in the weld
segment. This may be required because of discontinuity
in the work where different weld parameters are required.
See Operation chapter for a description of the weld sub
segment operation.
Tolerance Fault — This error is caused because of arc
voltage out of tolerance (± .5 Volt variance from
programmed value), wire feed speed out of tolerance (±
10 IPM variance from programmed value), or a loss of
arc established from the power source. If any of these
conditions continuously persist for more time than the
fault delay time the error will be recognized. If the fault
was caused by the loss of arc established, the panel will
shut off the power source and feeder automatically. This
type of error will clear itself once a new weld cycle is
initiated.
Trigger Hold — For semiautomatic applications. The
trigger hold feature allows the welder to initiate the weld
with a momentary pull of the switch, and terminate the
weld with another momentary pull of the switch. The full
description of this process is described in the
Semiautomatic section located in the Operation chapter
of this manual.
Trim — This capability allows the weld operator to change
the weld parameters arc voltage and WFS during the weld.
See Soft Switch section located in the Operation chapter.
Weld Cycle — A weld cycle is the completion of the
segments preflow through postflow once. Thus, if a
schedule dictates a recycle, this would be considered
multiple weld cycles.
Weld Segment — The weld segment is the segment
which describes the static part of the weld. This segment
will dictate if the weld is a spot weld (time non-
continuous), or a continuous weld.
WFS — wire feed speed.
