CASE FRONT CONTROLS (See Figure B.3b)
1. WIRE FEED SPEED/AMMETER DISPLAY- This
meter displays either the wire feed speed or current
value (Amps) depending upon the status of the wire
feeder and the power source. Written below the dis-
play is "WFS" and "Amps". A LED light illuminates
the units of the value displayed on the meter.
• Prior to CV welding, the meter displays the desired
preset WFS value.
• During welding, the meter displays the actual
amperage.
• After welding, the meter holds the actual current
value for 5 seconds. The display blinks to indicate
the Power Feed 15M is in the "Hold" period. If the
Wire Feed Speed knob is adjusted while in the
"Hold" period, the Power Feed 15M will revert to
the "Prior to welding" display described above.
The default wire feed speed units are inches/minute
and can be changed to meters/minute by entering
the "Extended Feature Menu" during power-up. The
wire feed speed is calibrated to within ±2%. Refer to
the power source manual for calibration specifica-
tions of the ammeter.
2. WIRE FEED SPEED KNOB - The Wire Feed Speed
knob that adjusts of the rate of feeding electrode.
3. VOLTAGE / TRIM DISPLAY - The voltage/trim
meter displays either the voltage or trim value,
depending upon the status of the wire feeder and
the power source.
The voltage display shows the actual average arc volt-
age during the welding.
After welding, the meter holds the actual average arc
voltage for 5 seconds. During this time, the display
flashes to indicate the product name is in the "Hold"
period. Output adjustment while in the "Hold" period
results in the "prior to operation" characteristics
described above.
The voltage is calibrated to ±2% over a range of 10 to
45 volts.
4. VOLTAGE / TRIM KNOB- The Voltage / Trim knob
is rotated to adjust the ideal voltage / trim for each
personal welding mode process used.

Voltage / Trim Display prior to operation
Displays the preset Voltage value
Displays the preset Voltage value.
Displays the preset Trim value from 0.50 to 1.50, with 1.00 as the default. Trim adjusts the arc length
for Pulse programs. Lower the trim value to decrease the arc length, and raise the trim value to
increase the arc length. A trim value of 1.00 is a setting for most conditions.
• Adjusts the background current of the STT waveform. Used to modify the heat input.
• Linc Net Power Sources: Displays the background current as a value from 0.50 to 1.50, with 1.00
as the default. Lower the trim value to decrease the heat input, and raise the trim value to increase
the heat input. A trim value of 1.00 is a good setting for most conditions.
• Arc Link Power Sources: Displays the background current in amps. Lower the background current
to decrease the heat input and raise the background current to increase the heat input.
Displays the preset CP value from 0 to 20. The Power mode is best for thin sheet metal and aluminum
applications.
