Lincoln Electric IM915 manual Volts / Trim Display, Prior to Welding, Synergic CV Voltage Display

b-6 OPERATION b-6

b. VOLTS / TRIM DISPLAY

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.

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 optimum 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.
DURING WELDING
Weld Process	Volts / Trim Display
All Processes	Displays Actual
	Average Arc Voltage

AFTER WELDING

Weld Process	Volt/Trim Display
All Processes	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 oper-
	ation" characteristics described above.

SYNERGIC CV VOLTAGE DISPLAY

Synergic CV programs feature an ideal voltage best suited for most procedures. Use this voltage as a starting 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 voltage. (upper bar displayed)

•Preset voltage at ideal voltage. (no bar displayed)

•Preset voltage below ideal voltage. (lower bar displayed)
