T I M E = X X .X
6. Define the shielding gas postflow time as desired.
The range for postflow is 0.0 to 25.0 seconds, in incre-
ments of 0.1 seconds.
7. Press Right/Increase, and the display shows:
# 0 X W I R E – F E E D S T A R T
D E L A Y = X X .X S E C.
8. Define the wire feed start delay as desired.
Wire feed start delay is the amount of time between the
end of initial current and when the wire feed user relay
(see Section 2-3) changes states. A delay time of 0
means the wire feed relay changes state immediately
at the end of initial current. A delay time of 3.5 means
the relay changes state 3.5 seconds after the end of ini-
tial current.
The wire feed relay change cannot be delayed beyond
the end of weld current. When weld current ends, the
wire feed relay changes states whether or not the de-
fined start delay time has elapsed.
The range for start delay time is 0.0 to 25.0 seconds, in
increments of 0.1 seconds.
9. Press Right/Increase, and the display shows:
# 0 X W I R E – F E E D S T O P
D E L A Y = X X .X S E C.
10. Define the wire feed stop delay as desired.
Wire feed stop delay is the amount of time between the
end of weld current and when the wire feed user relay
(see Section 2-3) changes states. A delay time of 0
means the wire feed relay changes state immediately
at the end of weld current. A delay time of 7.0 means
the relay changes state 7.0 seconds after the end of
weld current.
The wire feed relay change cannot be delayed beyond
the end of postflow. When postflow ends, the wire feed
relay changes states whether or not the defined stop
delay time has elapsed.
The range for stop delay time is 0.0 to 25.0 seconds, in
increments of 0.1 seconds.

12. If desired, press Start/Increase on the Remote Pend-
ant to carry out a dry run of the program (see Section
5-7 for information on the dry run feature). To place the
microprocessor control in the Ready condition, press
Right/Increase.
13. In the Ready condition the microprocessor control is
ready to have another program entered or to execute a
program. For information on executing a program, see
Section 6.

T I M E = X X .X
2. Define the final slope time as desired.
The range for final slope time is 0.0 to 25.0 seconds, in
increments of 0.1 seconds. Define the final slope time
as desired.
3. Press Right/Increase, and the display shows:
a. For Semi-Automatic 2 and 3 modes:
# 0 X F I N A L

b. For Semi-Automatic 4 mode:
# 0 X F I N A L
T I M E = X X .X A M P S = X X X .X
4. Define the final current time (if applicable) and amper-
age as desired.
The range for final current level time is 0.0 to 25.0 sec-
onds, in increments of 0.1 seconds. The range for final
level amperage varies from 2.0 to 400 amperes, in in-
crements of 1.0 amperes.
