The inverter technology used in the TELWIN FORCE 145 welder is a real breakthrough in the field of welding equipment. Unlike traditional transformer welders, the inverter allows a significant reduction in the weight and dimensions of the device, while maintaining, and even increasing, its performance and precision. At the heart of the system is a microprocessor that controls the flow of current at high frequency, resulting in an extremely stable and smooth welding arc.

For the professional welder, this means easier electrode guidance, less spatter and deeper fusion, resulting in welds of excellent quality and strength. Arc stability is crucial, especially when working with difficult materials or in demanding positions. What’s more, inverter technology is much more energy efficient, resulting in lower operating costs and less strain on the electrical grid. TELWIN FORCE 145 proves that powerful welding power does not have to go hand in hand with large dimensions.

The TELWIN FORCE 145 welder is equipped with advanced features that make the welding process more intuitive, efficient and safe. The Arc Force (arc dynamics) system automatically adjusts the welding current according to the arc length. When the arc becomes shorter (e.g., when the electrode gets closer to the material), the system increases the current, preventing dimming and facilitating the transfer of metal droplets. This ensures smooth welding and uniformity of the weld.

The Hot Start function delivers a pulse of higher current when the electrode is ignited. This is an invaluable aid, especially when working with electrodes that are difficult to ignite, or on cold or contaminated surfaces. With Hot Start, the arc ignites instantly and reliably every time. In turn, the Anti-Stick system prevents the electrode from sticking to the material being welded. In the event of a short circuit, the current is automatically reduced, allowing the electrode to be easily torn off without damaging it and without risking overheating the welder. These three functions work synergistically, significantly improving the comfort of work and the quality of the obtained connections.

The TELWIN FORCE 145 is designed for professionals for whom mobility and reliability are a priority. Its light weight (about 3.57 kg) and compact dimensions make it extremely easy to transport and store. It will easily fit in the trunk of a car, on a shelf in the workshop or in a toolbox. It’s ideal for welders working at heights, in tight spaces or who frequently change their work location.

Despite its small size, the FORCE 145 is solidly built and resistant to harsh operating conditions, as confirmed by its IP21 protection rating. Integrated thermal, overvoltage and undervoltage protections protect the key components of the welder from damage, guaranteeing long and trouble-free operation. The ability to be powered by a generator (with a minimum output of 5 kW) further enhances its versatility, allowing it to work in places without access to the electricity grid. This is a tool you can rely on in any situation.

When you choose the TELWIN FORCE 145 model in the ACX (Accessories) version, you not only get an excellent welder, but also a complete starter kit that will allow you to start working immediately and in complete safety. The key component of this kit is a high-quality automatic welding visor. It provides optimum protection for your eyes and face against UV/IR radiation and spatter, automatically adjusting the filter’s darkening level to the intensity of the welding arc.

In addition to the visor, the kit also includes welding cables – electrode holder and ground clamp – made of materials that guarantee good conductivity and durability. This means you don’t have to waste time and money selecting compatible accessories. Telwin has made sure that you can focus on what matters most – precise and efficient welding. The ACX kit is an investment in comfort, safety and immediate readiness for your projects.
