2.1 - Description

The RT4000 is a 400A (500A for the RT5000) constant current welding power source
based on IGBT technology. The Inverter drive circuitry operates above the audio fre-
quency spectrum making the RT4000/RT5000 virtually silent in operation. The high op-
erational frequency also means that the RT4000/RT5000 is able to respond quickly to
changing arc dynamics, making for a very smooth and stable arc.
