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 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 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 starting
point for most conditions.
Inductance and UltimArc
TM
UltimArc 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 nominal setting
of 0.0.
SMAW (Stick) Welding
SMAW is most often used for outdoor construction, pipe
welding and general repairs. The POWER WAVE

Non-Synergic GMAW and FCAW
Welding
In non-synergic modes, the WFS control is similar to a
conventional CV power source where WFS and voltage
are independent adjustments. Therefore to maintain the
arc characteristics, the operator must adjust the voltage
to compensate for any changes made to the WFS.
UltimArc™ Control, adjusts the apparent inductance of
the wave shape. The UltimArc™ Control adjustment is
similar to the "pinch" function in that it is inversely
proportional to inductance. Therefore, increasing
UltimArc™ Control greater than 0.0 results in a crisper
arc (more spatter) while decreasing the UltimArc™
Control to less than 0.0 provides a softer arc (less
spatter).

GMAW (MIG) Synergic Welding
In synergic welding modes, WFS is the dominant control
parameter. For each wire feed speed, a corresponding
voltage is programmed into the machine at the factory.
The user adjusts WFS according to factors such as wire
size, material thickness, penetration requirements, etc.
The Power Wave then uses the WFS setting to select
the appropriate voltage. The voltage selected will be a
nominal voltage. The user can adjust the voltage higher
or lower to compensate for material condition or
individual preference.
UltimArc™ Control, adjusts the apparent inductance of
the wave shape. The UltimArc™ Control adjustment is
similar to the "pinch" function in that it is inversely
