END OPTIONS
The downslope, crater, and burnback parameters are
used to define the end of the weld sequence. The 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 suffi-
cient 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 parame-
ter 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

(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 VOLTS
CRATER TIME
BURNBACK TIME
RESTRIKE TIME
