Technology creates change.
The ability to evolve along
with change is what
distinguishes a successful
product from the rest.
Power source design is
almost entirely devoted
to reliability. Fast power
conversion is important to
obtaining a smooth
welding output, but we
also know that speed is
inconsequential without
reliability. No matter how
fast your machine operates,
if it is not durable, then it is
not usable for welding. And
if it is not welding, you are
not meeting your
production goals and
making a living.
QUICKER RESPONSE
High-speed power conversion allows for quick response to changing
arc conditions.
SMALLER FOOTPRINT
Power electronic components are compact, making equipment size smaller and
therefore more portable.
UNIVERSAL INPUT VOLTAGE
Capable of operating from 208 to 575 volts on virtually any power supply for
versatile, consistent performance.
HIGHLY EFFICIENT
Smaller transformer coils, higher thermal conductivity, and higher operating
frequencies means more efficient output power, and more economical use
of power. This translates to decreased utility costs and increased power
source efficiency.
WAVEFORM CONTROL TECHNOLOGY

gives it equivalent power
capabilities as a
conventional
transformer/rectifier
such as the Lincoln
CV-305, but in
a much smaller and
portable machine.
