COMMON WELDING PROCEDURES
WARNING
MAKING A WELD
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.
Choose the electrode material, electrode size, shield- ing gas, and process (GMAW,
Select the weld mode that best matches the desired welding process. The standard weld set shipped with the POWER WAVE® R350 encompasses a wide range of common processes that will meet most needs. If a special weld mode is desired, contact the local Lincoln Electric sales representative.
All adjustments are made through the user interface. Because of the different configuration options your system may not have all of the following adjustments. See Accessories Section for Kits and Options avali- able to use with the POWER WAVE® R350.
Definition of Welding Modes

SYNERGIC WELDING MODES
•A Synergic welding mode offers the simplicity of single knob control. The machine will select the cor- rect voltage and amperage based on the Wire Feed Speed (WFS) set by the operator.
Basic Welding Controls
Weld Mode
Selecting a weld mode determines the output charac- teristics of the Power Wave power source. Weld modes are developed with a specific electrode materi- al, electrode size, and shielding gas. For a more com- plete description of the weld modes programmed into the POWER WAVE® R350 at the factory, refer to the Weld Set Reference Guide supplied with the machine or available at www.powerwavesoftware.com.

In constant voltage modes, this control adjusts the welding voltage.
Trim
In pulse synergic welding modes, the Trim setting adjusts the arc length. Trim is adjustable from 0.50 to
1.50.1.00 is the nominal setting and is a good start- ing point for most conditions.
