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 = 2
This message is then replaced by the following message:
SELECT A MEMORY
LOCATION
2.MEMORY RECALL NUMBERS: Select the mem- ory location of the desired welding procedure by pressing the appropriate MEMORY RECALL NUMBER key.
If no procedure was saved in the selected memo- ry location, the following message appears:
MEMORY LOCATION
#IS EMPTY
Select another memory location.
When a welding procedure is recalled from mem- ory, the display window will show the procedure description, wire feed speed, and arc length trim or preset voltage.
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 will 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 procedure, these limits will be active when this overlay is in place. They cannot be overridden from this over- lay.
3.PROGRAM LIST: The PROGRAM LIST block in the center of this overlay provides a convenient place to record a brief description of each welding procedure stored in memory. A “Dry Erase” mark- er should be used for this purpose.
4.DISPLAY RECALL KEY: To view other information about the selected procedure, press the DISPLAY RECALL key. The display window will show the procedure description and gas type of the se- lected procedure for as long as the key is held depressed. When the key is released, material type, wire size, and process descriptions will be displayed for a few seconds.
5.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.
6.MEMORY LIGHTS: A memory light is on when its corresponding memory is selected. This tells you what memory is active at any given time.
