2.1 Description
The RT2500 is a 250A constant current TIG welding machine based on IGBT tech-
nology. The Inverter drive circuitry operates above the audio frequency spec-
trum. The high operational frequency also means that the RT2500 is able to re-
spond quickly to changing arc dynamics, making for a very smooth, stable arc.
As well as TIG welding the RT2500 is capable of MMA welding with all types of
electrodes within the current rating of the machine, normally up to 5mm.
