Device functions & components
- Plasma / CUT - A plasma jet is generated by means of electricity, which melts the material, which is then removed with compressed air, allowing all conductive metals such as standard steel, stainless steel, copper, aluminum, titanium and many more to be cut precisely and effortlessly.
- Cutting thickness - Depending on the material, cuts of up to 14 mm are possible. Mild steel ST37 up to 14 mm, V2A or V4A up to 8 mm, aluminum up to 5 mm.
- Contact ignition - High-frequency (HF) contact ignition for first-class ignition behavior.
- Cutting current - Stepless adjustment from 15 to 50 A.
- Air after-run - After the cutting process is complete, air flows automatically to cool the torch and reduce wear on the nozzle and electrode.
Device features & advantages
- IGBT technology - The latest and most modern transistor technology enables the highest performance and duty cycle (ED) of 60 % at full power! No transformer, no MOSFET, state-of-the-art IGBT!
- Lightweight & compact design - With only 7.2 kg weight and dimensions of 400 x 175 x 280 mm, the device is ideal for cutting work anywhere. Innovative IGBT transistors save space and weight compared to the old MOSFET technology - no more heavy carrying!
- Highest efficiency & performance - single-phase alternating current (230 V) supplies the device and allows an output power of real 50 amps.
- Smart cooling & overheating protection - State-of-the-art technology, integrated overheating protection and high-performance cooling enable maximum power to be called up.
