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 Section 6-2 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 Section 6-2 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 Right 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.
