NOMINAL PROCEDURES

The Power Wave is designed to operate with 3/4" electrode stick-out for CV and Pulse processes and a 1/2" stick-out for STT processes.

FRINGE PROCEDURES

Excessively short or long electrode stick-outs may function only on a limited basis, if at all.

WELDING ADJUSTMENTS

All adjustments are made on the system component known as the User Interface (Control Box), which con- tains the switches, knobs, and digital displays neces- sary to control both the Power Wave and a Power Feed wire feeder. Typically, the Control Box is sup- plied as part of the wire feeder. It can be mounted directly on the wire feeder itself, the front of the power source, or mounted separately, as might be done in a welding boom installation.

MAKING A WELD

WARNING

The serviceability of a product or structure utiliz- ing the welding programs is and must be the sole responsibility of the builder/user. Many variables beyond the control of The Lincoln Electric Company affect the results obtained in applying these programs. These variables include, but are not limited to, welding procedure, plate chemistry and temperature, weldment design, fabrication methods and service requirements. The available range of a welding program may not be suitable for all applications, and the build/user is and must be solely responsible for welding program selec- tion.

-----------------------------------------------------------------------

The steps for operating the Power Wave will vary depending upon the options installed in the user inter- face (control box) of the welding system. The flexibility of the Power Wave system lets the user customize operation for the best performance.

First, consider the desired welding process and the part to be welded. Choose an electrode material, diameter, shielding gas and process (GMAW, GMAW- P, GMAW-STT, etc.)

Second, find the program in the welding software that best matches the desired welding process. The stan- dard software shipped with the Power Waves encom- passes a wide range of common processes and will meet most needs. If a special welding program is desired, contact the local Lincoln Electric sales repre- sentative.

To make a weld, the Power Wave needs to know the desired welding parameters. The Power Feed (PF) family of feeders communicate settings to the Power Wave through control cable connection. Arc length, wire feed speed, arc control, etc. are all communicat- ed digitally via the control cable.

Because the Control Box can be configured with many different options, your system may not have all of the following adjustments. Regardless of availability, all controls are described below. For further information, consult the Power Feed wire feeder instruction manu- al.

•WFS / AMPS:

In synergic welding modes (synergic CV, pulse GMAW, STT) WFS (wire feed speed) is the dominant control parameter, controlling all other variables. The user adjusts WFS according to factors such as weld size, penetration requirements, heat input, etc. The Power Wave then uses the WFS setting to adjust its output characteristics (output voltage, output current) according to pre-programmed settings contained in the Power Wave. In non-synergic modes, the WFS control behaves more like a conventional CV power source where WFS and voltage are independent adjustments. Therefore to maintain the arc character- istics, the operator must adjust the voltage to compen- sate for any changes made to the WFS.

In constant current modes (stick, TIG) this control adjusts the output current, in amps.
