GENERAL DESCRIPTION
The Power Wave 455/R power source is designed to
be a part of a modular, multi-process welding system.
It is a high performance, digitally controlled inverter
welding power source capable of complex, high-speed
waveform control. Depending upon configuration, it
can support constant current, constant voltage, surface
tension transfer and pulse welding modes. Each
machine is factory preprogrammed with multiple weld-
ing procedures. Typically these procedures include
GMAW, GMAW-P, FCAW, GTAW and STT (Surface
Tension Transfer) for a variety of materials such as
mild steel, stainless steel, cored wires and aluminum.
The STT process supports mild steel and stainless
steel welding.
The Power Wave 455/R has an output rating of either
450 amps at 38 volts or 400 amps at 36 volts. The two
output ratings are dependent upon input voltage and
frequency. Both have a duty cycle of 100%. The STT
process is rated at currents up to 325 amps at a 100%
duty cycle.
