Explore the Advanced Capabilities of the TELWIN TECNICA 171/S 230V
? Unmatched Mobility, Maximum Performance
The TELWIN TECNICA 171/S is revolutionizing the concept of mobile welding. Imagine the full power of a professional MMA and TIG welder enclosed in a housing weighing just 2.8 kg. Its compact dimensions (300x130x230 mm) allow it to be easily transported and work in places where traditional heavy welding equipment simply won’t fit. It’s ideal for professionals working in the field, at heights, assembling structures or in tight service spaces.
Despite its small size, the TECNICA 171/S offers an impressive welding current of up to 150A, allowing efficient welding with electrodes up to 4.0 mm in diameter. A sturdy shoulder strap and sturdy carrying case (included) further simplify portability, making it a tool that’s ready for action in all conditions. No longer do you have to choose between mobility and power – the TELWIN TECNICA 171/S delivers both.
? Intelligent Welder Support: Arc Force, Hot Start, Anti-Stick
At the heart of the TELWIN TECNICA 171/S welder are advanced microprocessor control systems that actively support the welder to guarantee excellent welding results. The HOT START function provides increased current at the moment of ignition, making it easier to get started even with difficult electrodes or in unfavorable conditions. It eliminates the risk of electrode “sticking” at start-up and ensures an instant, stable arc glow.
During welding, the ARC FORCE system dynamically regulates the arc current. When the arc shortens (which often happens when welding in forced positions), the system automatically increases the current, preventing the arc from dimming and “sticking” the electrode. This ensures a smooth and deep fusion, even when the distance between the electrode and the material fluctuates. This is complemented by the ANTI-STICK function, which immediately reduces the current when the electrode sticks, protecting the electrode from overheating and allowing it to be easily detached. These three technologies work together to make welding easier, faster and more efficient, with excellent weld quality.
?️ TELWIN Reliability: Safe and Working in All Conditions
The TELWIN brand is synonymous with Italian quality and reliability, and the TECNICA 171/S model is a prime example. The welder is designed for long-term and trouble-free operation, even in demanding professional environments. A key feature is the extensive safety system. Thermostatic protection protects the device from overheating, signaling the need for a break and automatically resuming operation after cooling down. Over-voltage and under-voltage prote ctions protect the electronics from voltage fluctuations in the grid, which is especially important when working with unstable power sources.
In addition, the TECNICA 171/S is suitable for use with generators (with a minimum power of 6 kW), making it an ideal tool for work in areas without access to the electrical grid. The IP23 degree of protection means resistance to solid objects with a diameter of more than 12.5 mm, as well as protection against water spray at an angle of up to 60° from the vertical. This combination of features provides the welder not only with safety, but also with the confidence that the device will stand up to the challenges of intensive daily work.

Key Features and Benefits
- ? Compact Design and Ultra-Lightweight: Thanks to advanced inverter technology, the TECNICA 171/S welder weighs just 2.8 kg and has a compact footprint (300x130x230mm). For the professional, this means unparalleled mobility, ease of transport and the ability to work in tight, hard-to-reach places without compromising on power. Installation work at heights or in the field becomes much less strenuous.
- ? HOT START (Hot Start) function: This system delivers increased welding current at the moment of arc ignition. In practice, this eliminates problems with starting welding, especially with cold or wet electrodes, and when welding materials with high thermal conductivity. The welder gains the assurance of an immediate start, which reduces preparation time and increases the fluidity of the work.
- ? ARC FORCE (Arc Dynamics) function: This intelligent function automatically increases the welding current when the arc becomes shorter (e.g., when the electrode is brought closer to the material), preventing it from extinguishing and sticking the electrode. This makes it possible to weld with a short arc even in difficult positions, ensuring deeper penetration and a more uniform weld. For the welder, this means a more stable process, fewer spatters and better control over the weld pool.
- ?️ ANTI-STICK (Anti-Collapse) function: If the electrode sticks to the material being welded, the ANTI-STICK function immediately reduces the welding current to a minimum. This prevents overheating and damage to the electrode, facilitates electrode detachment and protects the welder from overloading. The professional saves consumables and time, avoiding frustrating interruptions.
- ⚙️ MMA and TIG LIFT Welding Versatility: The TECNICA 171/S allows MMA welding with a wide range of covered electrodes (rutile, basic, stainless, cast iron) up to 4.0 mm in diameter. In addition, it offers TIG DC welding with LIFT ARC contact ignition, which is ideal for precision work on stainless steel, carbon steel or copper. This versatility makes it a versatile tool for a variety of tasks.
- ? Cooperation with Generator and Advanced Protection: The device is designed to work with power generators (minimum power of 6 kW) and has a number of protections: thermal, over-voltage, under-voltage and overload protection. This guarantees reliability and safe operation even in difficult power conditions, protecting the welder from damage and ensuring continuous operation.
