Trigger Memory Recall
Enable = Selecting memories 2 through 6 with
quick trigger pulls is enabled when the option-
al dual procedure/memory panel is installed.
To recall a memory with the gun trigger, quick-
ly 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 memo-
ry recall can only be performed when the sys-
tem is not welding. Disable = Memory selec-
tion is performed only by the buttons on the
optional dual procedure/memory panel.

Procedure Change Method (Three Settings)
In order for any of these procedure change methods
to function, the

"A-Gun-B"

switch must be on the

"Gun"

position.

"External Switch"

(the default value), the

machine will only change the selected procedure
when the procedure select digital input changes
state.

"Quick Trigger"

(the optional value 1), the

machine will only change the selected procedure
when the trigger is released and quickly re-pulled
while welding in 2-step. Enable=Allows switching
between procedure A and procedure B while
welding. The exception is that the procedure
select digital input is no longer recognized.

"Integral Trigger Procedure"

(the optional value

2), the machine will only change the selected pro-
cedure when the procedure select digital input
changes state. Machine operation is similar to
the

"External Switch"

selection except that addi-

tional logic prevents procedure A from being re-
selected when the trigger is quickly and com-
pletely released at step 2 of the 4-step weld
sequence. This selection is intended to be used
when a MIG gun with an integral procedure select
switch built into the trigger (e.g.DS400) is used
with 4-step welding.

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 fac-
tor 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.

Push Pull Gun, Gun Offset Adjustment The
push-pull 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 ipm.
• 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 nec-
essary, decrease the calibration setting to
slow the pull motor, or increase the calibra-
tion 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.
