•When the Feeder Set Up button is pressed while in standby, the Feeder Set Up push button LED illuminates and the top display will be active. Use the Adjust control to select preflow (PRE), start (STRT), crater (CRTR), or postflow (POST) parameters.

•Press the lower display push button to allow the bottom display to become active. The time LED will automatically begin flashing

and the unit will be in the time mode. Initially, all sequences will appear as off. Use the Adjust control display time and enable the time sequence. Setting a time automatically enables a sequence. To turn off a sequence, change time setting to OFF.

•If the sequence has a voltage or arc adjust setting, pressing the lower display push button a second time will cause either volts or arc adjust to appear on the display. Use the Adjust control to set either parameter.

•If the sequence has a wire feed setting, pressing the lower display push button a third time will cause wfs to appear on the display. Use the Adjust control to set wire speed parameter.

•Press the lower display push button a fourth time will cycle the display back to time.

•Press the Feeder Set Up button a second time to go to Trigger Control mode and allow

the top display to become active. Use the Adjust control to cycle through trigger control methods as follows: dual schedule, trigger hold, trigger dual schedule, program select, 4T (see Section 5-1). The lower display will show the current state of each trigger control method as being either on or off. Not all trigger control methods are compatible with each other, and turning on certain functions will cause other trigger functions to turn off.

•Press the lower display push button to allow the bottom display to become active. Use the Adjust control to turn selected trigger control methods on or off. If trigger hold is set to on, the trigger hold LED will illuminate. Note: if 4T is set to on, trigger hold will automatically be set to on since this parameter is necessary for the 4T function.

•Press the Feeder Set Up button a third time to cycle back to standby mode.
