1 Lower Display

The lower display shows WFS (wire feed speed), AMPS (amperage), ARC CTL (arc control), or Time. The feeder displays only preset wire speed at idle (not welding). While welding, the average amperage is displayed. The lower display shows welding sequence time when the Time LED is illuminated.

2 WFS (Wire Feed Speed) LED

LED illuminates to indicate the preset wire feed value is being displayed and can be adjusted using the Adjust knob.

4 Arc Ctl (Arc Control) LED

LED illuminates to indicate that inductance (MIG) or ARC [Pulse, Accu-pulse, or RMD (optional)] is being displayed and can be adjusted using the Adjust knob.

5 Time LED

LED illuminates to indicate that a time value is being displayed for a sequence function and can be adjusted using the Adjust knob.

6Lower Display Push Button

7Lower Display Push Button LED

Pressing the button illuminates the LED and selects either WFS or Arc Ctl value for changing using the Adjust knob.

During a welding program operation, it is possible to change WFS (wire feed speed) by using the Adjust knob regardless of the active program sequence that appears on the dis- play.

When the Arc Ctl LED is illuminated, it is possible to change values while welding by using the Adjust knob. To return to actual values on the display, exit the Arc Ctl display.

.The lower display push button has

additional functions when entering the sequence and trigger control functions (see Section 6-7).

3 Amps LED

LED illuminates to indicate the average amperage is being displayed while welding and for 3 seconds after welding is terminated. The amperage must be above a minimum value of 25 amps for this function to operate.

To select Arc Ctl, press and hold lower display button for 2 seconds. The top display will show either INDU for a MIG program or ARC for Pulse, Accu-pulse, or RMD (optional). To exit Arc Ctl or INDU, either press the upper display push button or press and hold the lower display push button for 2 seconds.
