Try different start delay times for yourself.
The start delay time can be set from 0 to 99.9
seconds.

Screen 4 STOP DELAY
STOP DELAY
This screen allows a stop delay to be set by turn-
ing the adjust knob to increase or decrease its
value. As the change is made, the number on
the display changes accordingly. (This feature
is only active if remote stop is used).
When the remote stop signal is received, wire
feed will continue until the stop delay has timed
out. After the stop delay has elapsed, wire feed
will stop.
The stop delay time can be set from 0 to 99.9
seconds.
The stop delay is used to stop the wire feed at
the correct time in the weld sequence. If the
wire feeder is part of a system and a power
supply with current downslope is being used,
it is recommended to stop the wire feed when
the current has sloped down to about 60% of its
weld value. If the total downslope time is set
to 10 seconds, a travel stop delay of 4 seconds
would be appropriate. Try different stop delay
times for yourself.
Press the touch pad with the down arrow to
proceed to the next screen.
Screen 5 WIRE RETRACT
WIRE RETRACT 0.3sec
This screen allows a time to be set during which
the wire retracts. When the wire feed stops,
3.9sec

the motor will reverse and travel at the wire
retraction speed defined in the set-up mode
(See Screen 11) for the length of time set in
this screen. The time can be set by turning the
adjust knob to increase or decrease its value. As
the change is made, the number on the display
changes accordingly.
Wire retract is used to avoid the wire freezing
into the weld pool at the end of the weld. The
retract time should be set to retract the wire out
of the pool but not so far that it moves outside
the gas shield. This would cause the end of the
wire, which is still hot as it leaves the weld pool,
to oxidize.
The wire retract time can be set from 0.0 to 9.9
seconds.
Press the touch pad with the down arrow to
proceed to the next screen.
If the control is supplied with the 9629-HW
Hot Wire Control option, the following screen
will appear.
Screen 6 RAMP TIME
RAMP TIME
This screen allows a time to be set during which
the wire speed ramps up from zero to the pro-
grammed wire feed speed level. The time can
be set by turning the adjust knob to increase or
decrease its value. As the change is made, the
number on the display changes accordingly.
The ramp time facility is used to provide a
gradual speed increase of the wire at the start of
a hot wire weld. This avoids "stubbing" of the
wire until the weld pool has grown large enough
to accept the high wire feed speed.
The ramp time can be set from 0.0 to 99.9 sec-
onds.
Press the touch pad with the down arrow to
