QUICK ST ART REFERENCE FOR USING THE PROCESS SELECTION OVERLA Y Read and understand the “Controls and Settings” and “Operating Overlays” sections of this manual before using the following Quick Start Reference pr ocedure to operate the Power W ave.
GENERAL DESCRIPTION The INVERTEC Power W ave power source is a high performance, digitally controlled inverter welding power source capable of complex, high-speed wave- form control. It uses thr ee-phase input power only . The Power W ave is designed to be used as a syner gic welding system in conjunction with a wire feeder .
CONTROLS AND SETTINGS All operator controls and adjustments ar e located on the case front of the Power W ave. Refer to Figure B.1 and corresponding explanations. FIGURE B.1 – CASE FRONT CONTROLS CASE FRONT CONTROLS Refer to Figure B.1 for the location of the following controls: 1.
OPERA TING OVERLA YS OVERVIEW The Power W ave is controlled by a panel of keys (key- pad) located on the front of the machine. The opera- tor can access controls by placing an overlay over the keys. An OVERLA Y is a special plastic sheet with a number of keys and symbols printed on one side and a bar code printed on the other .
OVERLA Y TYPES Four types of overlays can be used with the Power W ave. 1. Process Overlays. These overlays are used to create, save and r ecall specific welding proce- dures by selecting and adjusting the various weld- ing settings that have been programmed into the Power W ave at the factory .
1. LCD DISPLA Y WINDOW : Power up the machine with this overlay in place. When the Power W ave is turned on, the following message appears on the display for a few seconds: LINCOLN ELECTRIC VERSION X.
3. ELECTRODE CLASS UP/DOWN: Use the ELEC- TRODE CLASS UP or DOWN keys to select from the material types available for the selected process. Pr ess the ELECTRODE CLASS UP or DOWN key until the desired material type is dis- played.
10. RECALL FROM MEMOR Y KEY : This key is used to recall an existing pr ocedure fr om memory . Y ou can recall and use any of the pr eviously created welding procedur es that are stor ed in one of the eight memory locations. Simply press the RECALL FROM MEMOR Y key and then the appropriate MEMOR Y LOCA TION NUMBER key .
1. LCD DISPLA Y WINDOW: Power up the machine with this overlay in place. When the Power W ave is turned on, the following message appears in the display window for a few seconds: LINCOLN ELECTRIC V ersion X.X This display is followed by: OVERLA Y ID NUMBER = 2 This message is then replaced by the following message: SELECT A MEMOR Y LOCA TION 2.

When a pair of welding procedur es are r ecalled from memory , the display window will show the procedur e description, wire feed speed, and the preset voltage or ar c length trim of the LAST pro- cedure welded with. With this overlay in place, the wire feed speed and the preset voltage or ar c length trim can be changed from the wir e feeder .

When the Power W ave is turned on, the following message appears in the display window for a few seconds: LINCOLN ELECTRIC V ersion X.X This display is followed by: OVERLA Y ID NUMBER = 0 This message is then replaced by the following message: POWER WA VE SETUP 2.
When the “WA TER COOLER PRESSURE” light turns on, release the key . If this key has been pressed for 30 seconds and the ‘W A TER COOLER PRESSURE’ light still did not turn on, check the water cooler for adequate fluid level. 5. WIRE FEEDER 1 +/- POLARITY KEY : Press this key to change the present voltage sensing polari- ty of wire feeder 1.
Use the ELECTRODE SENSE LEAD KEY to select either the - output terminal or the electrode sense (67) lead for the positive voltage refer ence. The work sense (21) lead is used only in rare cir cum- stances. For most installations, use the WORK SENSE LEAD KEY to select the - output terminal for negative voltage refer ence.
OVERVIEW OF WELDING PROCEDURES FLUX CORED ARC WELDING (FCA W) AND GMA W PROCEDURES For each wire feed speed, a corr esponding voltage has been prepr ogrammed into the machine by welding experts. This prepr ogrammed voltage is the best average voltage for the procedur e at the given wire feed speed.

In Pulse processes: The wave control adjustment allows the fr equency set- ting to vary . Increasing the wave contr ol allows the fre- quency setting to increase, and decr easing the wave control allows the fr equency setting to decrease.
OVERLOAD PROTECTION THERMAL PROTECTION The Power W ave has thermostatic protection fr om excessive duty cycles, overloads, loss of cooling, and high ambient temperatures. When the power sour ce is subjected to any of these conditions or any of the con- ditions mentioned above, a thermostat will open.

THERMAL PROTECTION T wo normally closed (NC) thermostats protect the machine from excessive operating temperatur es. These thermostats are wir ed in series and are con- nected to the Control Boar d. One of the thermostats is located on the heat sink of a switch board, and the other is located on the main choke.
An FET is a type of transistor . FET s are semi- conductors well suited for high-frequency switching. Drawing A above shows an FET in a passive mode. There is no gate signal (zer o volts) from the source and, ther efore, no curr ent flow . The drain terminal of the FET may be connected to a voltage supply .
