PROCESS SELECTION OVERLAY

An operator can use this overlay to create a new welding procedure, save a newly created welding procedure, view an existing welding procedure, recall an existing welding procedure, and clear a memory location. See Figure B.4. The steps for performing each of these functions are given below.

This display is followed by:

OVERLAY ID

NUMBER = 1

A welding procedure is made up of seven compo- nents: process, material type, wire diameter, program, wire feed speed, voltage or arc length trim, and wave control. A new welding procedure is created by selecting a combination of these components from the ones that have been programmed into the Power Wave. See Figure B.4 for key locations.

NOTE: The following four selections should

always be performed in this order: process, elec- trode class, electrode size, electrode/gas type. Selecting a setting for one component narrows your choice of available settings in remaining com- ponents. This is why the order of performing the steps is important. However, if you make compo- nent selections out of order, the machine will prompt you to make a new selection for any set- tings that do not apply.

2.PROCESS SELECT KEY: Use the PROCESS SELECT key to select from the processes avail- able in the machine. Press the PROCESS SELECT key until the light by the desired process is lit.
