selected, connect here the output cable.
11. Auxiliary Output: 220Vac case front receptacle
auxiliary supply.
12. Devicenet Connector (5 pin): This optional module
can be used for DeviceNet capability. It will be a 5
pin sealed mini connector per ANSI B93.55M-1981.
13. Optional Robotic Wire Feeder Receptacle: For
Robotic platforms the Wire Drive Control Module is
required to drive the Power Feed-10R wire drive.
This module can be factory installed through our
automation division or field installed for robotic
applications.
The Wire Drive Control Module is also be equipped
with a terminal strip for making simple input signal
connections. It can be used to externally control the
basic wire drive function. It is divided into three
groups: Trigger group, Cold Inch group, and
Shutdown group.
14. Optional I/O Connector: The wire drive control
module is equipped with a terminal strip for making
simple input signal connections. It can be used to
externally control the basic wire drive functions like
Trigger, Cold Inch, gas purge and shutdown.
15. 455M/STT only: STT Stud: Depending by the type
of welding selected, connect here the output cable.
16. Optional Ethernet Connector: This module includes
the DeviceNet and EtherNet capability. The
DeviceNet uses a 5 pin sealed mini connector per
ANSI B93.55M-1981. The EtherNet uses a RJ5
connector.

Making a weld

The Power Wave is designed to operate with 19mm
(3/4") electrode stick-out for CV and Pulse processes.
Excessively short or long electrode stick-outs may
function only on a limited basis, if at all.
WARNING: 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.
The steps for operating the Power Wave will vary
depending upon the options installed in the user
interface (control box) of the welding system. The
flexibility of the Power Wave system lets the user
customize operation for the best performance.
First, consider the desired welding process and the part
to be welded. Choose an electrode material, diameter,
shielding gas and process (GMAW, GMAW-P, etc.).
Second, find the program in the welding software that
best matches the desired welding process. The
standard software shipped with the Power Waves
encompasses a wide range of common processes and
will meet most needs. If a special welding program is
desired, contact the local Lincoln Electric sales
representative.
To make a weld, the Power Wave needs to know the
desired welding parameters. The Power Feed (PF)
family of feeders communicate settings to the Power
Wave through control cable connection. Arc length, wire
feed speed, arc control, etc. are all communicated
digitally via the control cable.
Welding adjustments
All adjustments are made on the system component
known as the User Interface (Control Box), which
contains the switches, knobs, and digital displays
necessary to control both the Power Wave and a Power
Feed wire feeder. Typically, the Control Box is supplied
as part of the wire feeder. It can be mounted directly on
the wire feeder itself, the front of the power source, or
mounted separately, as might be done in a welding
boom installation.
Because the Control Box can be configured with many
different options, your system may not have all of the
following adjustments. Regardless of availability, all
controls are described below. For further information,
consult the Power Feed wire feeder instruction manual.
WFS / AMPS:
In synergic welding modes (synergic CV, pulse GMAW,
STT), WFS (wire feed speed) is the dominant control
parameter, controlling all other variables. The user
adjusts WFS according to factors such as weld size,
penetration requirements, heat input, etc. The Power
Wave then uses the WFS setting to adjust its output
characteristics (output voltage, output current) according
to pre-programmed settings contained in the Power
Wave. In non-synergic modes, the WFS control
behaves more like 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.
In constant current modes (stick, TIG) this control
adjusts the output current.
VOLTS / TRIM:
In constant voltage modes (synergic CV, standard CV)
the control adjusts the welding voltage.
In pulse synergic welding modes (pulse GMAW only) the
user can change the Trim setting to adjust the arc
length. It is adjustable from 0.500 to 1.500. A Trim
setting of 1.000 is a good starting point for most
conditions.
455M/STT only: In STT modes, the user can adjust the
Trim setting to change the overall heat input to the weld.

Welding mode

:
May be selected by name (CV/MIG, CC/Stick Crisp,
Gouge, etc.) or by a mode number (10, 24, 71, etc.)
depending on the Control Box options. Selecting a
welding mode determines the output characteristics of
the Power Wave. For a more complete description of
the welding modes available in the Power Wave, see the
explanation below.
