OPERATION
DUAL WIRE FEEDERS, DUAL PROCEDURE OVERLAY (OPTIONAL)
The Dual Wire Feeders, Dual Procedures Overlay is used when the Power Wave is equipped with two wire feed- ers and two guns with two position switches. Any welding procedure stored in memory locations 1, 2, 3, or 4 can be automatically recalled and used. See Figure B.7.

1.LCD DISPLAY WINDOW: Power up the machine with this overlay in place. When the Power Wave is turned on, the following message appears in the display window for a few seconds:
LINCOLN ELECTRIC
VERSION X.X
This display is followed by:
OVERLAY ID
NUMBER = 9
2.WIRE FEEDERS MEMORY CHART: The active welding procedure is determined by the active wire feeder and its gun switch position. The weld- ing procedure recall from memory is as follows:
Active | Gun Trigger | Memory Location |
Wire Feeder | Position | of Procedure |
#1 | A | 1 |
#1 | B | 2 |
#2 | A | 3 |
#2 | B | 4 |
Pull the trigger on either wire feeder.
Depending on the gun switch position, the corre- sponding memory location is automatically recalled. The wire feeders memory chart has no keys; it is simply a chart.
The display window will show the procedure description, wire feed speed, and the preset volt- age or arc length trim of the last active welding procedure.
2 | 3 |
With this overlay in place, the wire feed speed and the preset voltage or arc length trim can be changed from the wire feeder. The new values replace the previous values and become a perma- nent part of the procedure.
If limits have been set on the wire feed speed, volt- age or arc length trim of the selected procedures, these limits will be active when this overlay is in place. They cannot be overridden from this over- lay.
3.DISPLAY RECALL KEY:To view other information about the active welding procedure, press the DISPLAY RECALL key. The display window will show the procedure description and gas type of the last active procedure for as long as the key is held depressed. When the key is released, the wire size, material type, and process descriptions will be displayed for a few seconds.
4.HIGH TEMPERATURE LIGHT: The high tempera- ture light comes on when the internal machine temperature exceeds the allowed limit. Output is disabled until the machine cools down and the high temperature light goes out.
5.MEMORY LIGHTS: A memory light is on when its corresponding memory is slected. This tells you what memory location is active at any given time.
