One of the biggest advantages of the TELWIN SUPERIOR PLASMA 70 is its ability to work with both single-phase 230V and three-phase 400V. This feature, often underestimated, in practice opens up completely new possibilities for the professional. Imagine a situation where you are working in the field, where only a 230V outlet is available – the SUPERIOR PLASMA 70 still allows you to cut efficiently (up to 40A), completing most typical tasks. Then, when you return to the workshop or a large construction site with access to 400V, you can unleash the full power of 70A, cutting thicker materials at maximum speed.

This versatility eliminates the need to have two separate cutters or invest in expensive and bulky transformers. Automatic voltage detection simplifies operation – simply connect the device to the appropriate source. For companies providing mobile services or working in diverse locations, this is an invaluable advantage, translating into space, cost and time savings. In addition, the ability to work with power generators (with adequate power) makes it an ideal tool for work in places without access to the electricity grid.

The TELWIN SUPERIOR PLASMA 70 uses advanced inverter technology to revolutionize the plasma cutting process. Unlike traditional transformer-based power sources, invertors offer much better control over arc parameters. This translates into an extremely stable and concentrated plasma stream, which is key to achieving clean, smooth cutting edges with a minimal heat-affected zone. This means less material distortion and a reduction in the need for time-consuming finishing.

Another major benefit of inverter technology is high energy efficiency. Inverter devices use significantly less electricity compared to their transformer counterparts of the same power. For the professional, this means lower electricity bills and greener operation. In addition, this technology allows the construction of smaller and lighter devices, making the SUPERIOR PLASMA 70 relatively lightweight and easy to carry, increasing comfort and mobility on the job site.

Working in an industrial or workshop environment often involves harsh conditions – dust, voltage fluctuations or intense use. The TELWIN SUPERIOR PLASMA 70 is designed to meet these challenges with an extensive protection system. It includes thermal protection that prevents key components from overheating, automatically shutting down the unit if the safe temperature is exceeded.

In addition, the cutter is protected against surges and undervoltage in the power supply, which is especially important when working with generator sets or in areas with unstable power infrastructure. Overcurrent protection protects against the effects of overloading. Robust construction and a high IP23 rating ensure resistance to dust and moisture. All these mechanisms work together to ensure a long and trouble-free life of the device, minimizing downtime and service costs. For the professional, this means confidence that his investment is well protected and the equipment will serve reliably for many years.

SUPERIOR PLASMA 70 uses a contact pilot arc ignition system. Unlike older high frequency (HF) ignition systems, this mechanism is much safer for surrounding electronics. HF ignition can generate electromagnetic interference that adversely affects computers, PLCs or other sensitive equipment. The contact system eliminates this risk, which is crucial in modern automated workshops.

What’s more, the stable pilot arc allows efficient cutting of difficult materials, such as mesh, grids, perforated sheets, or surfaces covered with rust or paint. The arc does not extinguish upon momentary loss of contact with the base material, allowing for smooth cutting without the need for frequent re-ignition. This feature is invaluable for demolition work, cutting openwork parts or preparing surfaces. In addition, this model often offers a gouging function, allowing precise removal of welds or material defects, extending its versatility.
