This Esab Suprarex 3100 is a plasma cutting machine — sometimes referred to as a plasma cutter or CNC plasma table — used for the precision thermal cutting of metal profiles, tubes, and flat plate. Esab is a well-established Swedish welding and cutting manufacturer with a long history of supplying industrial cutting systems, welding equipment, and automation solutions to fabrication, shipbuilding, structural steel, and general metalworking industries worldwide.
Built in 2020 and currently located in Germany, this machine is presented in used condition and remains under power. It is configured for both tube cutting and flat cutting, making it a versatile platform for a wide range of cutting applications. The machine's X-axis runs along a guide length of 11,000 mm with dual motorisation, and it accommodates tubes up to 8,000 mm in length with diameters ranging from 100 mm to 750 mm and wall thicknesses from 3 mm to 20 mm. A single synchronised axis spindle handles tube rotation during cutting, and three manually positioned tube support carriages, adjusted via trapezoidal screw, provide stable workpiece support throughout the process. A flat cutting table fitted with slats, measuring 1,500 x 1,000 mm, extends the machine's capability to sheet and plate work.
The plasma source is an Esab iSeries300 generator mounted on a dedicated carriage. It delivers a rated output of 300 A, with a current adjustment range spanning 5 A to 300 A. The supplied voltage is 180 V and the power supply is 380 V at 50/60 Hz. The unit achieves a 100% duty cycle at 40 °C, meaning it is rated for continuous operation at full power. Plasma gas options include air, oxygen, argon-hydrogen, and nitrogen, while shielding gas options cover air, nitrogen, oxygen, and water injection — a broad compatibility range that supports cutting across various material types and thicknesses.
A key feature of this machine is its VBA WRIST bevel cutting unit, which enables bevel, V-groove, and Y-groove cuts in addition to standard flat cutting. Torch height control is provided through both arc voltage sensing and a touch sensor specifically suited to bevel cutting, while tangential control is maintained throughout the cutting path. A plasma torch collision protection system is fitted as a safety measure, and a photocell-based safety system is also integrated into the machine.
Control is handled by the Esab Vision T5 CNC, which features an 18.5-inch colour touchscreen monitor designed to be operable with gloves. The control system includes the OPWizard application and the Esab Pipe Cutting programming software, supporting efficient programming of tube cutting operations including complex bevel profiles. The machine is supplied with manuals and CE certification.
