.For more information on Setting Sequence Parameters see Section
•The Sequence push button allows the selection of welding sequences. Five weld- ing sequences are available. The default sequence is the Weld sequence. The Weld sequence is active on power up. Three welding sequence LEDs are located above the Sequence push button: Start, Crater, and Preflow/Postflow. The applicable LED illuminates to indicate which welding se- quence is active.
•The LED illuminates to indicate that a weld- ing sequence display mode other than Weld is active. Welding sequences other than Weld must be set prior to initiating the arc. When the unit enters a welding state, all se- quence display modes are terminated and
the weld display mode is activated.
If zero time is programmed for a timed se- quence except for Weld, that sequence will be skipped.
•In the weld sequence display mode, the Se- quence push button LED is Off. When the Sequence push button is pressed, the Se- quence push button flashes and the Start LEDs flash. In this condition, the unit is in the Start sequence display mode, and Start se- quence parameters are displayed (see Sec- tion
•When the Sequence push button is pressed a second time, the Crater sequence LED flashes. The Sequence push button LED re- mains flashing. In this condition, the unit is in the Crater sequence display mode, and Crater sequence parameters are displayed.
•When the Sequence push button is pressed a third time, the Preflow/Postflow sequence LED flashes. The Sequence push button LED remains flashing. In the Preflow display mode the upper display shows the preflow time and the lower display indicates the ab- breviation PRE, to inform the operator that preflow time is displayed. If the upper dis- play push button is pressed, the Adjust con- trol can be used to adjust preflow.
•If the lower display push button is pressed, the Adjust control can be used to select be- tween preflow (PRE) and postflow (POST). When POST is selected, the upper display can be used to specify postflow time.
•When the Sequence push button is pressed a fourth time, the unit returns to the welding sequence display mode.
