START OPTIONS OPERATION
Pressing the
Arc Start/End Options
pushbutton will
illuminate the START OPTIONS LED and the Arc
Delay Time parameter will show on the MSP Display.
Use the
Mode Select Panel Control
to select the
desired delay time. Press the
Weld Mode Selector
to
exit the Start parameters. Repeated pressing of the
Arc Start/End Options
pushbutton will scroll through
the parameters. Turning the
Mode Select Panel
Control
, while on a parameter will change its value.
When a Start Option is set to a value other than OFF,
the START OPTIONS LED will blink synchronous with
the WFS or Amps and/or the Volts LED located on the
Dual Display Panel prompting the user to enter these
parameters. The parameters that can be set by the
user in the START OPTIONS will be as follows:
ARC DELAY TIME
STRIKE WFS
STRIKE TIME
START WFS/AMPS
START VOLTS
START TIME
UPSLOPE TIME
END OPTIONS
The downslope, crater, and burnback parameters are
used to define the end of the weld sequence. They are
defined in the following:
•
DOWNSLOPE
determines the amount of time it
takes to ramp from the weld parameters to the crater
parameters. The transition is linear and may be up or
down depending on the relationship between the
weld and crater settings.
•
CRATER
parameters are typically used to fill the
crater at the end of the weld and include both time
and output settings.
•
BURNBACK
defines the amount of time the output
remains on after the wire has stopped. This feature
is used to prevent the wire from sticking in the weld
puddle and to condition the end of the wire for the
next weld. A burnback time of 0.4 second is sufficient
in most applications.
•
RESTRIKE TIME
determines how long the system
will try to re-establish the arc in the event of a poor
start or if the arc goes out for any reason (short cir-
cuit or open circuit). During restrike, the WFS and
outputs are driven in an attempt to re-establish the
arc.
• A restrike time of 1 to 2 seconds is sufficient
in most applications.
• A restrike time of 0 seconds allows the
restrike function to continue indefinitely.
END OPTIONS OPERATION
Pressing the
Arc Start/End Options
pushbutton after
scrolling through the Start Options will illuminate the
END OPTIONS LED and the Downslope Time para-
meter will show on the MSP Display.
Use the
Mode Select Panel Control
to select the
desired delay time. Press the
Weld Mode Selector
to
exit the End parameters. Repeated pressing of the
Arc
Start/End Options
pushbutton will toggle through the
parameters. Turning the
Mode Select Panel Control
while on a parameter will change its value. When the
Crater Time is set to a value other than OFF, the END
OPTIONS LED will blink synchronous with the WFS or
Amps LED (depending on CC or CV Weld Modes) and
with the Volts LED located on the Dual Display Panel
prompting the user to enter these parameters. The
parameters that can be set by the user in the END
OPTIONS will be as follows:
DOWNSLOPE TIME
CRATER WFS/AMPS
CRATER VOLTS
CRATER TIME
BURNBACK TIME
RESTRIKE TIME
