GENERAL DESCRIPTION

The Power Wave 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, Surface Tension Transfer
and pulse welding modes.

The Power Wave power source is designed to be used
with the family of Power Feed wire feeders, operating
as a system. Each component in the system has spe-
cial circuitry to “talk with” the other system compo-
nents, so each component (power source, wire feeder,
electrical accessories) knows what the other is doing at
all times. The components communicate using ArcLink
protocol.

Robotic systems can communicate with other industri-
al machines via DeviceNET protocol. The result is a
highly intigrated and flexible welding cell.

The Power Wave 455/R is a high performance, digital-
ly controlled inverter welding power source capable of
complex, high-speed waveform control. Properly
equipped, it can support the GMAW, GMAW-P, FCAW,
GTAW 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.

If the duty cycle is exceeded, a thermostat will shut off
the output until the machine cools to a reasonable
operating temperature.

DESIGN FEATURES AND ADVANTAGES

• Designed to the IEC 974-1 Standard.

• Power Wave 455 multiple process output ranges:

5 - 570 amps

• Easy access for input connections. Connections are

simple strip and clamp (no lugs required).

• F.A.N. (Fan As Needed). Cooling fan runs only when

necessary (above Code 10500 only, and all STT
machines).

• Modular construction for easy servicing.

• Thermostatically protected.

• Electronic over-current protection.
