Key Features and Benefits

• ? Advanced Inverter Technology: At the heart of the device is a state-of-the-art inverter circuit that converts the mains current into high-frequency welding current. This solution not only ensures a much lighter weight and size compared to traditional transformer welders, but most importantly, it guarantees a stable, smooth welding arc and precise control over the process. For the welder, this means easier electrode ignition, fewer spatters, deeper penetration and the ability to weld a wide range of electrodes, including rutile, alkaline, stainless steel and cast iron, resulting in higher weld quality and versatility.
• ? Intelligent HOT START System: This function automatically increases the welding current at the very beginning of the process, the moment the arc is struck. This prevents the electrode from sticking to the material, and the arc ignites instantly and steadily, even with cold or damp electrodes or on rusted surfaces. The professional will appreciate the time savings, the elimination of the frustration of a problematic start, and a cleaner weld start without the risk of a faulty joint at the beginning of the stitch.
• ?️ Dynamic Arc Control ARC FORCE: This system monitors the welding arc voltage in real time and automatically adjusts the current to prevent it from extinguishing when the arc length is shortened (e.g., when the electrode is too close to the material). This ensures a smooth transfer of electrode material into the weld pool, makes it easier to weld in forced positions, and allows the machine to work with different types of electrodes, even those that are more difficult to guide. The result is a more homogeneous weld, better remelting and greater control over the process, which is key to achieving durable and aesthetically pleasing joints.
• ? ANTI-STICK system to prevent electrode sticking: If the electrode is short-circuited and sticks to the material being welded, the Anti-Stick function immediately reduces the welding current to a minimum value. This allows the electrode to be easily detached without damaging it (overheating the core) and without risking damage to the electrode holder or the welder itself. For the user, this means less material loss, longer life of electrodes and accessories, and greater operational safety, eliminating the need to forcibly peel off a stuck electrode.
• ⚙️ Comprehensive Equipment Security: The TELWIN FORCE 145 is equipped with a number of safety features to protect the key components of the welder. These include thermostatic protection (against overheating), overvoltage protection (protecting against power surges), undervoltage protection (ensuring stable operation during voltage drops) and overload protection. In addition, the welder has a tolerance for fluctuations in the supply voltage of +/- 15%, making it ideal for use with power generators. All this translates into high reliability, long life of the device and safety of use even in difficult operating conditions.
• ✈️ Unmatched Mobility and Compact Design: Weighing only about 2.8 kg by itself and delivered in a sturdy carrying case, the FORCE 145 is synonymous with mobility. Its compact size allows it to be easily stored and transported, making it an ideal choice for field work, at heights, in tight spaces, and for anyone who needs reliable equipment ready to go at a moment’s notice. This feature is invaluable for service technicians, assemblers and hobbyists who value order and ease of carrying equipment.
