B. Control Descriptions
1.
Left Side Controls Select Button
Press and release this button to activate the wire feeder left side controls. The LEFT text below the button will
illuminate and the swooshes above the volts/arc length adjustment knob and wire feed speed adjustment knob will
illuminate. See Welding Power Source Owner's Manual for the procedure to select the appropriate MIG process type
parameters. Pressing the left side welding gun trigger will also active the left side controls.
When in Pulse or RMD, holding the Left Side Select button for more than two seconds will activate Arc Control. "ARC"
will be shown on the lower display and the Arc Control value on the upper display. The setable range is −25 to +25 with
0 as nominal. Increasing Arc Control value increases the arc cone width and subsequently effects the arc length (end
of electrode to workpiece distance). Decreasing Arc Control value decreases the arc cone width and subsequently
effects the arc length (electrode to workpiece distance).
When in MIG or FCAW, holding the Left Side Select button for more than two seconds will activate Inductance Control.
"IND" will be shown on the lower display and the Inductance Control value on the upper display. The setable range is 0
to 99 with nominal setting being program specific. An increase in inductance will decrease the number of short circuit
transfers per second (provided no other changes are made) and increase the arc-on time. The increased arc-on time
makes the welding puddle more fluid. A decrease in inductance will increase the number of short circuit transfers per
second (provided no other changes are made) and decrease the arc-on time. The decreased arc-on time makes the
welding puddle less fluid.
2.
Volts/Arc Length Display
This display shows the voltage setting for MIG and FCAW processes (10.0 to 44.0 volts), and it shows the arc length
for RMD and Pro-Pulse processes (−3.0 to +3.0 in 0.1 increments with 0 as nominal). The actual arc voltage is
displayed while welding and continues to appear for 10 seconds after the welding arc is extinguished. Dashes appear
on the display when other welding processes are selected.
3.
Volts/Arc Length Adjust Knob
Use this knob to adjust the desired voltage setting (10.0 to 44.0 volts) or arc length setting (−3.0 to +3.0 in 0.1
increments with 0 as nominal) depending on the type of MIG process selection. Rotating the knob clockwise increases
volts/arc length and counter-clockwise decreases volts/arc length. Volts/arc length adjustment is active when the
swoosh above the knob is illuminated. The setting can be different for left and right sides, and the unit will hold these
settings for both sides.
4.
Right Side Controls Select Button (Dual Feeder Only)
Press and release this button to activate the wire feeder right side controls. The RIGHT text below the button will
illuminate and the swooshes above the volts/arc length adjustment knob and wire feed speed adjustment knob will
illuminate. See Welding Power Source Owner's Manual for the procedure to select the appropriate MIG process type
parameters. Pressing the right side welding gun trigger will also active the right side controls.
When in Pulse or RMD, holding the Right Side Select button for more than two seconds will activate Arc Control. "ARC"
will be shown on the lower display and the Arc Control value on the upper display. The setable range is −25 to +25 with
0 as nominal. Increasing Arc Control value increases the arc cone width and subsequently effects the arc length (end
of electrode to workpiece distance). Decreasing Arc Control value decreases the arc cone width and subsequently
effects the arc length (end of electrode to workpiece distance).
When in MIG or FCAW, holding the Left Side Select button for more than two seconds will activate Inductance Control.
"IND" will be shown on the lower display and the Inductance Control value on the upper display. The setable range is 0
to 99 with nominal setting being program specific. An increase in inductance will decrease the number of short circuit
transfers per second (provided no other changes are made) and increase the arc-on time. The increased arc-on time
makes the welding puddle more fluid. A decrease in inductance will increase the number of short circuit transfers per
second (provided no other changes are made) and decrease the arc-on time. The decreased arc-on time makes the
welding puddle less fluid.
5.
Wire Feed Speed Display
This display shows the wire feed speed setting when any of the MIG process types are selected and the display is
blank when other processes are selected. The wire feed speed range that can be displayed is from 50 to 780 ipm (1.3
to 19.8 mpm). Also, when the jog button is pressed the current jog speed appears on the display.
