GENERAL DESCRIPTION

The Power Wave semi-automatic power source is
designed to be a part of a modular, multi-process
welding system. Depending on configuration, it can
support constant current, constant voltage, and pulse
welding modes. The surface tension transfer mode is
supported only by the 455/STT.
The Power Wave power source is designed to be
used with the semi automatic family of Power Feed
wire feeders, operating as a system. Each component
in the system has special circuitry to "talk with" the
other system components, so each component (power
source, wire feeder, user interface) knows what the
other is doing at all times. These components commu-
nicate with Linc-Net.
The Power Wave 455/STT is a high performance, dig-
itally controlled inverter welding power source capable
of complex, high-speed waveform control. Properly
equipped, it can support the GMAW, GMAW-P,
FCAW, SMAW, GTAW, CAC-A, and STT processes.
It carries an output rating of either 450 amps, 38 volts;
or 400 amps, 36 volts (both at 100% duty cycle),
depending on input voltage and frequency. The
Surface Tension transfer process (STT) is supported
at currents up to 325 amps, at 100% duty cycle.
RECOMMENDED PROCESSES AND
EQUIPMENT
RECOMMENDED PROCESSES
The Power Wave 455/STT can be set up in a number
of configurations, some requiring optional equipment
or welding programs. Each machine is factory prepro-
grammed with multiple welding procedures, typically
including GMAW, GMAW-P, FCAW, SMAW, GTAW,
CAC-A, and STT for a variety of materials, including
mild steel, stainless steel, cored wires, and aluminum.
The STT process supports mild steel and stainless
steel welding.
The Power Wave 455/STT is recommended for semi-
automatic welding, and may also be suitable for basic
hard automation applications.
OPERATION
RECOMMENDED EQUIPMENT
Power Wave 455/STT – Semi-Automatic Operation
Semi Automatic Power Waves can only be used with
Linc-Net compatible Power Feed semi-automatic wire
feeders. In addition, the Power Feed semi-automatic
wire feeders may require optional equipment to
access certain weld modes in the Power Wave. Other
models of Lincoln feeders, or any models of non-
Lincoln wire feeders, cannot be used.
All welding programs and procedures are selected
through the Power Feed semi-automatic user inter-
face

REQUIRED EQUIPMENT

Any Linc-Net compatible semi-automatic wire feeding
equipment. Specifically, the semi-automatic Power
Feed family (PF-10, PF-10X2, PF-11).

LIMITATIONS

• The Power Waves are not to be used in outdoor
environments.
-----------------------------------------------------------------------
• The Power Wave 455/STT will support a maximum
average output current of 570 Amps (60% Duty
Cycle) on the standard Power Wave stud, and a
maximum average output current of 325 Amps
(100% Duty Cycle) on the STT stud.
• Only Linc-Net compatible Power Feed semi-auto-
matic wire feeders and users interfaces may be
used. Other Lincoln wire feeders or non-Lincoln wire
feeders cannot be used.

DUTY CYCLE AND TIME PERIOD

The Power Feed wire feeders are capable of welding
at a 100% duty cycle (continuous welding). The power
source will be the limiting factor in determining system
duty cycle capability. Note that the duty cycle is based
upon a ten minute period. A 60% duty cycle repre-
sents 6 minutes of welding and 4 minutes of idling in a
ten minute period.
