TELWIN SUPERIOR PLASMA 70: dual voltage power and cutting precision for professionals.
Forget compromises and equipment limits. The TELWIN SUPERIOR PLASMA 70 is an inverter plasma cutter made for professionals who expect full reliability, versatility and the highest cut quality in normal workshop conditions. Picture a unit that adapts to your workplace, whether you have a single-phase 230V supply in the workshop or a three-phase 400V supply in the production hall. The SUPERIOR PLASMA 70 is your key to efficient work on many materials, from carbon steel through stainless steel to aluminium, copper and brass.
Tired of equipment that cannot keep up with your projects? This cutter was designed to meet the hardest tasks. With a maximum cutting current of 70A (at 400V) it cuts steel up to 25 mm thick with excellent edge quality, and severs up to 30 mm. That means faster order turnaround, fewer corrections and more throughput in your workshop. Inverter technology gives not only a stable arc and precise cutting, but also clear energy savings and a smaller unit, which translates into mobility and comfort at work.
The TELWIN SUPERIOR PLASMA 70 is more than a tool, it is a partner in your daily work. Fitted with a set of protections, thermal, overvoltage, undervoltage and overcurrent, it supports long and trouble-free operation even in intensive industrial use. The intuitive control panel with legible indicators lets you follow the working parameters as you go, and contact striking with a pilot arc removes high frequency (HF) interference, protecting sensitive electronics nearby.
Whether you produce steel structures, carry out maintenance work or offer specialist cutting services, the SUPERIOR PLASMA 70 gives you the power, precision and reliability you need to stay ahead of the competition. Invest in technology that raises the quality of your services and improves your production processes.
Explore the advanced capabilities of the TELWIN SUPERIOR PLASMA 70 230V/400V
Supply flexibility: 230V and 400V power in one unit
One of the biggest strengths of the TELWIN SUPERIOR PLASMA 70 is its ability to work both on single-phase 230V and on three-phase 400V. This function, often undervalued, opens entirely new possibilities for a professional in practice. Picture a job in the field where only a 230V socket is available, the SUPERIOR PLASMA 70 still cuts efficiently (up to 40A) and covers most typical tasks. Back in the workshop or on a large site with access to 400V, you release the full 70A and cut thicker material at maximum speed.
This versatility removes the need for two separate cutters or for costly and bulky transformers. Automatic voltage detection simplifies operation, you only connect the unit to the available source. For companies offering mobile services or working in varied locations this is a real advantage in space, cost and time. The option of running on generator sets (of suitable output) also makes it a fitting tool for work in places without mains supply.
Inverter technology: precision, output and energy savings
The TELWIN SUPERIOR PLASMA 70 uses advanced inverter technology, which reshapes the plasma cutting process. Unlike traditional transformer power sources, inverters offer much better control over the arc parameters. The result is an exceptionally stable and concentrated plasma jet, which is the basis for clean, smooth cut edges with a minimal heat affected zone. That means less material distortion and less need for time consuming finishing.
Another important benefit of inverter technology is high energy efficiency. Inverter units draw far less electricity than their transformer counterparts of the same power. For a professional this means lower electricity bills and more economical work. The technology also allows units with smaller dimensions and lower weight, which makes the SUPERIOR PLASMA 70 relatively light and easy to carry, adding comfort and mobility at the workstation.
Advanced protections and reliability in hard conditions
Work in an industrial or workshop setting often means hard conditions, dust, voltage fluctuations and intensive use. The TELWIN SUPERIOR PLASMA 70 was designed to meet that, thanks to an extended protection system. It includes thermal protection, which prevents overheating of key components by switching the unit off automatically when the safe temperature is exceeded.
The cutter is also protected against overvoltage and undervoltage in the supply network, which matters when working with generator sets or in places with unstable power infrastructure. Overcurrent protection guards against the effects of overload. Solid construction and a high IP23 protection rating give resistance to dust and moisture. All these mechanisms work together to provide a long and trouble-free service life of the unit, cutting downtime and service costs. For a professional this means the certainty that the investment is well protected and that the equipment will serve reliably for many years.
Intelligent arc striking and specialist cutting
The SUPERIOR PLASMA 70 uses a contact pilot arc striking system. Unlike older high frequency (HF) striking systems, this mechanism is far safer for the surrounding electronics. HF striking can generate electromagnetic interference that affects computers, PLC controllers and other sensitive devices. The contact system removes that risk, which is decisive in modern, automated workshops.
A stable pilot arc also allows efficient cutting of difficult material such as mesh, grating, perforated sheet and surfaces covered with rust or paint. The arc does not go out when contact with the base material is briefly lost, so the cut can be guided smoothly without frequent re-striking. This function is invaluable in demolition work, cutting of openwork parts and surface preparation. On top of that, this model often offers a gouging function, allowing precise removal of welds or material defects, which extends its scope of use.

Key features and benefits
- Versatile dual voltage supply (230V/400V): This distinctive feature lets the unit adapt automatically to the available supply, single-phase 230V or three-phase 400V. For a professional it means maximum flexibility and mobility, with no need for several units or costly adapters. Work without trouble in a smaller workshop and on large industrial sites alike, always using the full potential of the cutter.
- Advanced inverter technology: At the heart of the SUPERIOR PLASMA 70 is a modern inverter circuit that keeps the plasma arc stable and concentrated. That translates into outstanding cutting precision, clean edges that reduce the need for further machining and high energy efficiency. For you it means faster work, lower running costs and the ability to cut complicated shapes with excellent quality, even under long loads.
- Multi-level protection system: The unit carries protections on several levels: thermal, overvoltage, undervoltage and overcurrent. Intelligent sensors monitor the key working parameters and protect both the cutter and the operator. For a professional this is an assurance of trouble-free work, longer equipment life and safety, even in hard industrial conditions.
- Contact pilot arc striking (no HF): This system provides reliable and immediate striking of the plasma arc without high frequency (HF). It removes the risk of electromagnetic interference that could affect other electronic devices nearby (CNC controllers, computers and the like). For you it means stable operation and protection of your workshop equipment.
- Efficient cutting of mesh and perforated material: Thanks to a purpose-shaped arc characteristic and advanced control, the SUPERIOR PLASMA 70 copes well with cutting mesh, grating and other perforated materials, holding the arc even over an interrupted surface. That means a clear saving of time and material, with no stoppages and no need to strike the arc again, which is decisive in many specialist applications.
- Intuitive operation and legible indicators: The control panel was designed for simplicity and efficiency. Clear LED indicators report the state of the unit, the presence of voltage, the tripping of thermal protections and correct air pressure. For a professional this means easy set-up, fast diagnostics and full control over the cutting process, with less risk of errors and stoppages.
