1.2 Introduction
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.
Features
• Fabricated in robust external casing to withstand the most extreme environments
• Safety circuits which protect against overloading and short circuits
• Arc force control for maximum user control
• Fan assisted cooling with
thermostatic protection
