The R1500 is a 150 amp constant current MMA welding machine based on IGBT technology. The inverter drive circuitry operates above the audio frequency spectrum making the R1500 virtually silent in operation.

The high operational frequency also means that the R1500 is able to respond quickly to changing arc dynamics, making for a very smooth stable arc. The R1500 is capable of welding with all types of electrodes within the current rating of the machine, normally up to 4mm.

The R1500 is able to TIG weld using a TIG torch with a built in gas valve using the ‘scratch start’ technique. It is available in three versions, a dedicated 230v, dedicated 115V and a 115/230V auto switching dual Voltage version
