COMMON WELDING PROCEDURES
MAKING A WELD
The serviceability of a product or structure utilizing 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 selection.
Choose the electrode material, electrode size, shielding gas, and
process (GMAW, GMAW-P etc.) appropriate for the material to be
welded.
Select the weld mode that best matches the desired welding
process. The standard weld set shipped with the Power Wave
®
S350 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 avaliable to use

Definition of Welding Modes
NON-SYNERGIC WELDING MODES
• A
Non-synergic
welding mode requires all welding process
variables to be set by the operator.
SYNERGIC WELDING MODES
• A
Synergic
welding mode offers the simplicity of single knob
control. The machine will select the correct 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 characteristics of
the Power Wave
®
power source. Weld modes are developed
with a specific electrode material, electrode size, and shielding
gas. For a more complete description of the weld modes
programmed into the Power Wave
®
S350 at the factory, refer to
the Weld Set Reference Guide supplied with the machine or
available at
www.powerwavesoftware.com.
Wire Feed Speed (WFS)
In synergic welding modes (synergic CV, GMAW-P), WFS is the
dominant control parameter. The user adjusts WFS according to
factors such as wire size, penetration requirements, heat input,
etc. The Power Wave
®
S350 then uses the WFS setting to adjust
the voltage and current according to settings contained in the
Power Wave.
In non-synergic modes, the WFS control behaves like a
conventional power source where WFS and voltage are
independent adjustments. Therefore, to maintain proper arc
characteristics, the operator must adjust the voltage to
compensate for any changes made to the WFS.
Amps
In constant current modes, this control adjusts the welding
amperage.
Volts
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 starting point for most conditions.
UltimArc™ Control
UltimArc™ Control allows the operator to vary the arc
characteristics. UltimArc™ Control is adjustable from –10.0 to
+10.0 with a nominal setting of 0.0.
