EXTENDED FEATURES MENU
The Extended Features Menu gives access to the set-
up configuration. Stored in the set-up configuration
are user preferences that rarely change, like calibra-
tion test modes or wire feed speed units.
To access the Extended Features Menu, turn power
OFF to the feeder and then hold the SELECT switch
in the up position. Continue to hold while the Power
Feed 15M powers up. Release the SELECT switch
when the display shows the first user preference that
may be changed.

User Preference
WFS/AMPS knob
The left display shows the User Preference number
and is changed with the WFS/AMPS knob. The right
display shows the present setting and is changed with
the VOLTS/TRIM knob.
Rotate the WFS/AMPS knob to the desired User
Preference. User Preferences for the Power Feed
15M are:
P0
On = Enter the Extended Features Menu
Off = Exit the Extended Features Menu
P1
On = m/min wire feed speed units
Off = In/min wire feed speed units (default)
P2
On = The left display shows Amperage while
welding .
Off = The left display shows Wire Feed Speed
while welding. (default).
P101 On = All weld modes and test modes are
accessible. The test modes allow for calibra-
tion of the power supply. When wire feeder
power is turned off, User Preference P101 will
revert back to the "Off" and only the weld
modes will be available.
Off = Only weld modes are accessible
(default).
P513 Adjust the stall factor for a push-pull gun.
OPERATION
The stall factor controls the torque of the wire drive
inside the Power Feed 15M when using a push-pull
gun. The Power Feed 15M is factory set to generate
enough torque for pushing the electrode but not so
much as to cause bird nesting. Check for other feed-
ing problems before adjusting the stall factor.
Default value for the stall factor is 25, with a range of
5 - 35.
To change the stall factor:
VOLTS
TRIM
P514
Setting
The push-pull gun offset calibration adjusts the wire
feed speed calibration of the pull motor. The proce-
dure should only be performed when other possible
corrections do not solve the push-pull feeding prob-
VOLTS/TRIM knob
lems. A rpm meter is required to perform the pull gun
motor offset calibration.
To perform the calibration procedure:
POWER FEED 15M
• 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.
Adjust pull gun offset.
• Release the pressure arm on both the pull and push
wire drives.
• 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.
