MAKING A WELD WITH WAVEFORM
TECHNOLOGY POWER SOURCES
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, GMAW-P etc.) appro-
priate 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 300C 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.
Regardless of availability, all controls are described in
the following section ( See Figure B.4 Panel Controls
Used)
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 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 at the factory, refer to the
Weld Set
Reference Guide

.
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 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 current.
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
TM
CONTROL
UltimArc
TM
Control allows the operator to vary the arc
characteristics from “soft” to “crisp”. UltimArc™ Control
is adjustable from –10.0 to +10.0 with a normal
setting of 0.0.
