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.
