4.ELECTRODE SIZE UP/DOWN: Use the ELEC- TRODE SIZE UP or DOWN keys to select from the wire diameters available for the selected process and material type. Press the ELECTRODE SIZE UP or DOWN key until the desired wire diameter is displayed.

5.ELECTRODE/GAS TYPE UP/DOWN KEYS: Use the ELECTRODE/GAS TYPE UP or DOWN keys to select from the programs available for the select- ed process, material type, and wire diameter. Press the ELECTRODE/GAS TYPE UP or DOWN Key until the desired program is displayed.

6.WAVE CONTROL UP/DOWN KEYS: Press one of the two WAVE CONTROL keys to display the pre- sent wave control. This is shown on a scale from LO to HI. Use the WAVE CONTROL UP or WAVE CONTROL DOWN key to change the wave control to the desired level. When this scale is shown, the WAVE CONTROL setting can also be changed while welding (on the fly). Press the DISPLAY RECALL key to exit the wave control function. For a description of how the wave control setting affects the welding procedure, refer to the Overview of Welding Procedures sub-section of the Operation section of this manual.

The wire feed speed and voltage or arc length trim desired for the new procedure can be changed from the wire feeder.

7.DISPLAY RECALL KEY: Since not all the informa- tion about the procedure can be seen on the 2-line LCD display window at the same time, use the DISPLAY RECALL key to display and verify all of the selected procedure information. The normal default display window shows the Procedure Description, WFS, and preset voltage or arc length trim values. Press and hold the DISPLAY RECALL key, and the window shows the procedure de- scription and gas type for as long as the key is held depressed. Release the DISPLAY RECALL key, and the window shows wire size, material type, and process description. After a few sec- onds, the window changes back to the default dis- play.

8.SAVE TO MEMORY KEY: This key is used to save a newly created welding procedure. The Power Wave has eight memory locations which can be used to store all the settings of up to eight welding procedures. Once stored in a memory location, a procedure can be recalled for later use with the RECALL FROM MEMORY key. To save a newly created welding procedure:

Press the SAVE TO MEMORY key SAVE and then one of the MEMORY LOCATION NUMBER keys. Keep a record of this number for future reference.

Any previously created welding procedure stored in that location will be erased.

If you press the SAVE TO MEMORY key but decide not to save the procedure, you can exit this function by pressing the DISPLAY RECALL key.

9.MEMORY LOCATION NUMBER KEYS: To view information about any stored welding procedure, simply press its MEMORY LOCATION NUMBER key.

As you hold down the selected key, the procedure description and gas type of the procedure appear in the display window. The process type is shown by the indicating light opposite the appropriate process symbol.

When you release the selected key, the wire size, material type and process description appear for a few seconds.

This function does not display the wire feed speed and voltage or arc length trim settings. To view these, you must recall the procedure from memo- ry with the RECALL FROM MEMORY key.
