OPERATION
When a pair of welding procedures are recalled from memory, the display window will show the procedure description, wire feed speed, and the preset voltage or arc length trim of the LAST pro- cedure welded with.
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 procedures, these limits will be active when this overlay is in place. They cannot be overridden from this over- lay.
3.THE 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 active procedure, press the DISPLAY RECALL key. The display window will show the procedure description and gas type of the active procedure for as long as the key is held depressed. When the key is released, the wire size, material type, and process descriptions dis- play 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 location is active at any given time.
