R2500

 

 

 

 

Important Information 

The R2500 is a 250 constant current welding power source 

based on IGBT technology. The Inverter  drive circuitry operates 

above the audio frequency spectrum making the R2500 virtu-

ally silent in operation. The high operational frequency also 

means that the R2500 is able to respond quickly to changing 

arc dynamics, making for a very smooth , stable arc. 

The R2500 is capable of TIG welding with the addition of an 

external TIG control unit (TIG300).
