COMMON WELDING PROCEDURES
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 builder/user is and
must be solely responsible for welding program
selection.
The steps for operating the Power Wave
®
S700 will
vary depending upon the user interface of the welding
system. The flexibility of the Power Wave
®
S700 lets
the user customize operation for the best perfor-
mance.
Find the program in the welding software that best
matches the desired welding process. The standard
software shipped with the Power Waves S700 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
®
S700 needs to
know the desired welding parameters. Waveform
Control Technology™ allows full customization of
Strike, Run-in, Crater and other weld parameters for
exacting performance.
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 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
®
S700 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
®
S700 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
®
S700 then uses the WFS setting to adjust the
voltage and current according to settings contained in
the machine.
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 start-
ing 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.
