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, 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.
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.
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) WFS (wire feed speed) is the dominant con- trol 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) accord- ing to
In
In constant current modes (stick, TIG) this control adjusts the output current, in amps.
•VOLTS / TRIM:
In constant voltage modes (synergic CV, standard CV) the control adjusts the welding voltage.
In pulse synergic welding modes (pulse GMAW only) the user can change the Trim setting to adjust the arc length. It is adjustable from 0.500 to 1.500. A Trim set- ting of 1.000 is a good starting point for most condi- tions.
• WELDING MODE
May be selected by name (CV/MIG, CC/Stick Crisp, Gouge, etc.) or by a mode number (10, 24, 71, etc.) depending on the Control Box options. Selecting a welding mode determines the output characteristics of the Power Wave power source. For a more complete description of the welding modes available in the Power Wave, see the explanation following.
