Enables exit from menu
Enables change WFS units:

"Metric" (factory default) = m/min;

"English" = in/min.
This option allows a memory to be recalled by quickly pulling and releasing
the gun trigger:

"Enable" = Selecting memories 2 through 9 by quickly pulling and
releasing the gun trigger. To recall a memory with the gun trigger, quickly
pull and release the trigger the number of times that correspond to the
memory number. For example, to recall memory 3, quickly pull and
release the trigger 3 times. Trigger memory recall can only be performed
when the system is not welding.

"Disable" (factory default) = Memory selection is performed only by the
Panel Buttons.
This option selects how remote procedure selection (A/B) will be made. The
following methods can be used to remotely change the selected procedure:

"External Switch" (factory default) = Dual Procedure selection may only
be performed by the Cross-switch gun or remote control.

"Quick Trigger" = Allows switching between Procedure A and procedure
B while welding with 2-stroke mode. The Cross-switch gun or remote
control is required. To operate:
Select " WFS/Proced. A-B" in P.25 to set up parameters for A and B

procedures.
 Start the weld by pulling the gun trigger. The system will weld with
procedure A settings.
 While welding, quickly release and then pull the gun trigger. The
system will switch to procedure B settings. Repeat to switch back to
procedure A settings. The procedure can be changed as many
times as needed during the weld.
 Release the trigger to stop welding. When the next weld is made,
the system will start again with procedure A.

"IntegralTrigProc" = Allows switching between Procedure A and
procedure B while welding with 4-stroke mode. When in 2-step, the
system operates identical to the External Switch selection. To operate in
4-step:
Select " WFS/Proced. A-B" in P.25 to set up parameters for A and B

procedures.
 Start the weld by pulling the gun trigger. The system will weld with
procedure A settings.
 While welding, quickly release and then pull the gun trigger. The
system will switch to procedure B settings. Repeat to switch back to
procedure A settings. The procedure can be changed as many
times as needed during the weld.
Release the trigger to stop welding. When the next weld is made, the
system will start again with procedure A.
This option adjusts the wire feed speed calibration of the pull motor of a
push-pull gun. This should only be performed when other possible
corrections do not solve any push-pull feeding problems. An rpm meter is
required to perform the pull gun motor offset calibration. To perform the
calibration procedure do the following:
1. Release the pressure arm on both the pull and push wire drives.
2. Set the wire feed speed to 200 ipm.
3. Remove wire from the pull wire drive.
4. Hold an rpm meter to the drive roll in the pull gun.
5. Pull the trigger on the push-pull gun.
6. Measure the rpm of the pull motor. The rpm should be between 115
and 125 rpm. If necessary, decrease the calibration setting to slow
the pull motor, or increase the calibration setting to speed up the
motor.

The calibration range is -30 to +30, with 0 as the default value.
This option is used to skip the Crater sequence when making short tack
welds. If the trigger is released before the timer expires, Crater will be
bypassed and the weld will end. If the trigger is released after the timer
expires, the Crater sequence will function normally (if enabled).

OFF (0) to 10.0 seconds (default = Off)
