MAKING A WELD WITH WAVEFORM
TECHNOLOGY POWER SOURCES
WARNING
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 tem-
perature, weldment design, fabrication methods and ser-
vice requirements. The available range of a welding pro-
gram 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 materi-
al to be welded.
Select the weld mode that best matches the desired welding
process. The standard weld set shipped with the Power Wave
C300 encompasses a wide range of common processes that
will meet most needs. If a special weld mode is desired, con-
tact 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 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 pro-
grammed into the Power Wave at the factory, refer to the Weld
Set Reference Guide supplied with the machine or available at
www.powerwavesoftware.com.
OPERATION
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 conven-
tional 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 cur-
rent.
VOLTS
In constant voltage modes, this control adjusts the welding volt-
age.
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

teristics from "soft" to "crisp". UltimArc™Control is adjustable
from –10.0 to +10.0 with a nominal setting of 0.0.
