Recalling from Memory
To recall the contents of a memory into the active proce- dure, momentarily push the desired memory button (for less than 2 seconds). The saved parameters will be copied into the active procedure, and the LED of the memory button will light indicating the source of the infor- mation. As with saving to memory, this light will remain lit as long as the contents of the source memory remain equal to the contents of the associated procedure.
If a constant current mode is saved to memory with the power source in the "on" state, the "on" status will be changed to "off" when the procedure is recalled. This pre- vents a potential safety hazard if a memory button is pushed and the power source unexpectedly turns on.
2 STEP / 4 STEP OPERATION
The Wire Drive has a 2 Step / 4 Step switch located near the gun connector.
2 Step Synergic Operation:
Without Start/Crater/Burnback functions active
Waveform Sequence:
1.Trigger is pulled; Preflow sequence begins and runs until preflow timer expires.
2.Strike sequence initiates until Arc is established.
3.Arc established; Weld sequence begins.
4.Trigger released (Arc extinguished); Postflow sequence begins and runs until postflow timer expires.
5.End of sequence.
2 Step Synergic Operation: With Burnback function active.
Waveform Sequence:
1.Trigger is pulled; Preflow sequence begins and runs until preflow timer expires.
2.
3.Arc established; Weld sequence begins.
4.Trigger released (Arc extinguished); Burnback sequence begins and runs until burnback timer expires.
5.Postflow sequence begins and runs until postflow timer expires.
6.End of sequence.

WFS vs. Work point (Output) Waveform
= solid line represents WFS
2 Step Synergic Operation:
With Start/Crater/Burnback functions active.
Waveform Sequence:
1.Trigger is pulled; Preflow sequence begins and runs until preflow timer expires.
2.
3.Arc established; Start sequence begins and runs for the amount of time set.
4.Weld sequence begins.
5.Trigger released; Crater sequence begins and runs until crater timer expires.
6.Arc Extinguished; Burnback sequence begins and runs until burnback timer expires.
7.Postflow sequence begins and runs until postflow timer expires.
8.End of process.
