Switch when using a Lincoln Dual Schedule gun.
When in 2-step, the system operates identical to the
External Switch selection. To operate in 4-step:
 Select procedure "GUN" on the memory panel.
 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.
 Release the trigger to stop welding. When the
next weld is made, the system will start again
with procedure A.

External Switch = Dual Procedure selection may
only be performed by the memory panel button or a
dual procedure gun (default).
P.6 Push Pull Gun, Stall Factor Adjustment
The stall factor controls the stall torque of the push
motor when using a push-pull gun. The wire feeder is
factory set to not stall unless there is a large resistance
to feeding wire. The stall factor can be reduced to stall
more easily and possibly prevent bird nesting. However,
low stall factors can cause motor stalling while welding
which results in the wire burning back to the tip. If you
are experiencing bird nests, check for other feeding
problems before adjusting the stall factor. Default value
for the stall factor is 75, with a range of 5 - 100. To
change the stall factor:

Use the VOLTS/TRIM knob to adjust the stall factor.
Increasing the stall factor raises the motor torque
and decreasing the stall factor lowers the motor
torque. Do not increase the stall factor more than
necessary. A high stall factor may increase the
occurrence of bird nesting and a low stall factor may
cause the wire to burn back to the tip.

Press the right hand button to save the new setting.
P.7 Push Pull Gun, Gun Offset Adjustment
The pushpull gun offset calibration adjusts the wire feed
speed calibration of the pull motor. The procedure
should only be performed when other possible
corrections do not solve the push-pull feeding problems.
A rpm meter is required to perform the pull gun motor
offset calibration. To perform the calibration procedure:

Release the pressure arm on both the pull and push
wire drives.

Set the wire feed speed to 200 rpm.

Remove wire from the pull wire drive.

Hold the rpm meter to the drive roll in the pull gun.

Pull the trigger on the push-pull gun.

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.

Press the right hand button to save the new setting.
P.8 TIG Gas Control (Two Settings)

1. "Valve (manual)", the internal solenoid will not
actuate while TIG welding, gas flow is manually
controlled by an external valve.

2. "Solenoid (auto)", the internal gas solenoid will
turn on and off automatically while TIG welding as
follows:
 Preflow time will not be accessible from the
MSP4.
 Postflow time will be available in the MSP4
"End Options" and have a range of OFF to 10.0
English
seconds.
 The postflow time value is maintained when
switching between MIG and TIG modes.
When machine output on/off is controlled via

the right encoder, gas flow will not start until the
tungsten touches, the work piece, gas flow will
stop after the postflow time when the arc is
broken.
 When machine output on/off is controlled via an
arc start switch or foot Amptrol, gas will begin
flowing when the output is turned on and stop
flowing after the postflow period after the output
is turned off.
P.9 Crater Delay
Use the crater delay to skip the Crater sequence when
making short tack welds. If the trigger is released before
the Crater Delay Timer ends, then the Crater sequence
is skipped. If the trigger is released afterwards, the
Crater sequence functions normally.

Values = OFF to 10.0 seconds (OFF is default).
P.11 Set Timers
This menu is used to adjust timer values for Upslope,
Downslope and Restrike. Press the right button to enter
the Set Timer menu. Rotate the knob to select the timer
to adjust and then press the right button. Adjust the
value of the timer by rotating the knob. Press the left
MSP4 button to set the value and exit. Continue to
adjust other timers as necessary, and then press the left
button to exit the Set Timer menu.
P.12 Travel Options
This menu is used to change the travel options for a
travel carriage, including starting and ending functions.
The right MSP4 button to enter the Travel Options menu
and rotate the encoder to select either starting or ending
options. Press the right MSP4 button to select the
option. Press the left MSP4 button to set the value and
exit. Rotate the encoder to select other options, or press
the left MSP4 button to exit the menu.
P.13 Adjust Arc Force
Use this menu to adjust Arc Force values for Start, Weld
and Crater. Press the right MSP4 button to enter the
menu and rotate the knob to choose either Start, Weld or
Crater. Press the right MSP4 button and then rotate the
knob to the desired value. Press the left MSP4 button to
set the value and exit. Continue to adjust Arc Force for
other states, and then press the left MSP4 button to exit
the menu.
P.14 Reset Consumable Weight
This parameter only appears with systems using
Production Monitoring. Use this parameter to reset the
initial weight of the consumable package.
P.16 Push-Pull Gun Knob

Gun Pot Enabled = The wire feed speed is always
controlled by the potentiometer on the push-pull gun
(default).

Gun Pot Disabled = The wire feed speed is always
controlled by the left display knob on the feeder.

Gun Pot Proc A = When in procedure A, the wire
feed speed is set by the push-pull gun
potentiometer. When in procedure B, the wire feed
speed is set by the left display knob on the feeder.
