Setup

For typical system setup connections refer

to Section 7-7.

Rotate Mode Switch to V-SENSE FEEDER

position as shown.

The Left Display toggles between open cir-

cuit voltage and the trim setting. The open

circuit voltage is shown while the Volts Indi-

cator is lit, and the trim setting is shown

while the Arc Length Indicator is lit.

Operation

While the Arc Length Indicator is lit under

the Left Display, the Adjust Control is used

to set desired trim setting.

. The Left Display toggling momentarily

pauses while the trim setting is ad-

justed.

Pressing the Setup Button allows adjust-

ment of Arc Control, Wire Type, Gas Type

and Arc Length.

. For best results, select the appropriate

Wire and Gas Type to match the actual

wire and gas being used.

Refer to Pulsed MIG − Wire and Gas Selec-

tion Table for available wires and gases

(see Section 7-5).

Selecting a Wire and Gas

Press the Setup Button repeatedly until the

Wire Type indicator is lit. The active Wire

Type will appear in the Left and Right Dis-

play.

Rotate Adjust Control to select desired

wire.

Press the Setup Button again so the Gas

Type indicator is lit. The active Gas Type

will appear in the Left and Right Display.

Rotate Adjust Control to select desired gas.

Press the Setup Button again to confirm the

selection. The unit will acknowledge a

change of wire and gas information by dis-

playing PROG LOAD momentarily.

Arc Control (SharpArc)

Press the Setup Button repeatedly until the

Arc Control indicator is lit. SHRP appears

on the Left Display, and the corresponding

SharpArc setting appears on the Right Dis-

play.

Rotate Adjust Control to select desired

SharpArc setting from 0 to 50, default is 25.

Adjusting the SharpArc setting changes the

welding arc cone. Lower settings widen the

arc cone, increases puddle fluidity and flat-

tens the weld bead appearance.

Higher settings narrow the arc cone, re-

duces puddle fluidity and crowns the weld

bead appearance.

. Each Wire and Gas Type combination

has independent Arc Length and Shar-

pArc settings. These settings are pre-

served when the unit is turned off.

Arc Length (Trim)

Trim corresponds to the level of energy

needed to burn off the welding electrode.

As wire feed speed increases, a higher trim

setting is required to burn off the additional

wire. The trim setting appears in the Left

Display when the Arc Length Indicator is lit.

Trim can be adjusted from 0 to 100.

Prior to arc initiation, the unit displays the

letter “R” and a reference wire speed (IPM)

on the Right Display. The reference wire

speed can be used as a starting point for

the wire speed setting at the feeder. The

wire speed and trim can then be further ad-

justed to achieve the desired arc length.

The Configuration Option Menu (see Sec-

tion 5-3) can be used to change the Arc

Length setting from trim (0 to 100) to aver-

age arc voltage. Average arc voltage can

be used as an alternative method to set the

Pulsed MIG welding arc with the same pa-

rameters (voltage and wire speed) as a

conventional MIG arc. Lower voltage set-

tings correspond to tighter arc lengths while

higher voltage settings correspond to lon-

ger arc lengths. If the voltage mode is se-

lected, the average preset voltage will be

displayed on the Left Display with the Volts

Indicator lit.
