B. VOLTS / TRIM DISPLAY AND OUTPUT KNOB

The voltage/trim meter displays either the voltage or
trim value, depending upon the welding process
(mode) being used and the status of the wire feeder
and power source.
Below the meter are the words "Volts" and "Trim". An
LED light illuminates to designate which value is being
displayed on the meter. The knob below the meter
adjusts the value displayed in the meter. The following
tables describe the function of the Volts / Trim display
depending upon the status of the wire feeder / power
source package and the welding process utilized.
PRIOR TO WELDING
Weld Process Volts / Trim Display prior to operation
Nonsynergic CV Displays the preset Voltage value.
Synergic CV Displays the preset Voltage value.
Synergic Displays the preset Trim value from 0.50
CV-Pulse 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 opti-
mum for most conditions.
Synergic CV-STT • 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 opti-
mum 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.
Nonsynergic Displays the preset CP value from 0 to 20.
Power The Power mode is best for thin sheet
metal and aluminum applications.

SYNERGIC CV VOLTAGE DISPLAY

Synergic CV programs feature an ideal voltage best
suited for most procedures. Use this voltage as a start-
ing point for the weld procedure and adjust if needed
for personal preferences.
The voltage is calibrated to ±2% over a range of 10 to
45 volts.
When the voltage knob is rotated, the display will show
an upper or lower bar indicating if the voltage is above
or below the ideal voltage.
• Preset voltage above ideal
• Preset voltage at ideal
• Preset voltage below ideal

Volt/Trim Display
After welding, the meter holds the actual
average arc voltage for 5 seconds. During
this time, the display flashes to indicate
the wire feeder is in the "Hold" period.
Output adjustment while in the "Hold"
period results in the "prior to operation"
characteristics described above.
