1 Lower Display

The lower display shows wire speed or amperage. The unit displays and adjusts only preset wire speed at idle. When the unit is in a welding state, actual wire speed is displayed for the active welding sequence.

2 Lower Display Push Button

3 Lower Display Push Button LED

The lower display push button LED illuminates

to indicate that information displayed can be changed by the Adjust control.

4Wire Speed LED

5Amps LED

The LEDs below the display illuminate to indi- cate which value is being shown.

If the unit is in a welding state that does not involve feeding wire, the unit displays the weld sequence wire speed. At any time dur- ing welding, the weld sequence wire speed can be adjusted and overrides the preset wire speed display. In other words, if the Ad-

just control is activated while welding, the unit displays and permits adjustment of the weld sequence wire feed speed regardless of the active welding sequence.

When the unit is displaying amperage, the Amps LED illuminates. Amperage is only displayed if the unit is in a welding state and the amperage is above a minimum value of 25 Amps.

The display will read dashes for amperage readings below the amperage threshold, prior to arc initiation.

When the Setup button is pressed, the Set- up push button LED flashes and the Trigger Hold LED flashes.

The flashing LED indicates that the unit is in the trigger hold display mode. In this mode the upper display indicates HOLD and the lower display indicates the trigger hold sta- tus On/Off. Use the Adjust control to change

the trigger hold status or press the lower dis- play push button. If trigger hold is turned On, the trigger hold LED illuminates and stays On.

When trigger hold is On, the user must press and hold the trigger for a predefined amount of time (the trigger hold delay time− see Section 5-12), then release it for the trig- ger hold function to be active. To shut off the weld when trigger hold is On, the user must press and release the trigger.

If a weld time is programmed, trigger hold is disabled.

Trigger hold and dual schedule cannot be used concurrently.

When the Setup button is pressed a second time, the dual schedule LED flashes. In this mode the upper display indicates DUAL and the lower display indicates dual schedule status On/Off. Use the Adjust control to change the dual schedule status if desired.

Pressing the Setup button again exits the Setup mode. The dual schedule LED stops flashing to indicate the dual schedule status is Off.

While in the Setup mode, the active program can be adjusted without deactivating the trigger hold Setup mode operation. If the trigger is activated, Setup mode(s) is termi- nated.
