Setup 1
1. Footswitch Weld Abort
From the
SETUP 1
screen, press the
1
key to toggle between
ON
and
OFF
. This function controls how
the Control interfaces with a foot switch, a force firing switch, or a programmable logic control (PLC).
Any of these switches could be the weld initiation switch in your system setup.
ON
means that the welding process is initiated by closure of the initiation switch and continues to its
conclusion while the initiation switch remains closed. If the initiation switch opens during the welding
process, the welding process will terminate. The
ON
state is preferred for human operated welding
stations since it allows you to abort the weld process by releasing the foot switch (or the foot pedal in the
case of a manually actuated weld head).
OFF
is preferred for computer or PLC controlled welding stations since a single start pulse can be used
to initiate the welding process. To select the
ON/OFF
states, press the
1
key. The
FOOTSWITCH WELD
ABORT
line will now reflect your selection.
2. Switch Debounce Time
The contacts of single pole mechanical firing switches “bounce” when they close. The switch de-
bounce time function allows you to specify that the initiation switch contacts must remain closed for 10,
