TELWIN SUPERMIG 350i with Dual Voltage technology is a real breakthrough in power supply flexibility. Forget the dilemmas of 400V three-phase mains availability. This intelligent device automatically recognizes and adapts to the connected source – be it a standard 230V single-phase outlet or an industrial 400V installation.

For a professional welder, this means unlimited possibilities. Working in a smaller workshop with limited infrastructure? The SUPERMIG 350i will deliver impressive power even on 230V. Fulfilling a job in a large production hall or construction site with access to 400V? The unit will utilize its full potential, guaranteeing maximum productivity. This versatility eliminates the need for several different machines, reduces costs and simplifies logistics, allowing you to focus on getting the job done perfectly, whatever the conditions.

The TELWIN SUPERMIG 350i takes MIG/MAG welding to a new level with advanced microprocessor-managed synergy programs (often referred to as OneTouch LCD Synergy on Telwin models). No more time-consuming and often frustrating trial-and-error parameter selection. Simply select the type of material to be welded, wire diameter and shielding gas type on the easy-to-read control panel.

The synergy system will automatically set the optimal welding parameters, such as arc voltage and wire feed speed, providing the ideal conditions for creating a high-quality weld from the first moment. Of course, experienced welders still have the option to fine-tune these settings manually to adapt the arc characteristics to their specific preferences or unusual applications. This feature drastically reduces set-up time, minimizes the risk of errors and guarantees reproducible results, which is crucial in batch production and for jobs requiring the utmost precision.

At the heart of the TELWIN SUPERMIG 350i is a powerful inverter module that delivers a stable 350 Amperes of welding current. Such power, combined with a high duty cycle, makes this semi-automatic machine the ideal tool for the most demanding welding tasks. You can easily handle welding of thick steel sheets and profiles, realization of complex structures or intensive work in production conditions.

Advanced inverter technology not only provides high power, but also excellent arc dynamics and precise control over the welding process. This means deeper fusion, less spatter and more aesthetically pleasing welds, reducing the time needed for post-processing. Whether you’re working on steel structures, in heavy industry or in advanced repair shops, the SUPERMIG 350i will provide you with reliable power and performance that translates into faster projects and a higher quality final product.

The TELWIN SUPERMIG 350i is not just about power and synergy, but also advanced features that allow precise calibration of welding arc characteristics. Professionals will appreciate the ability to adjust key parameters such as electronic inductance, which affects the smoothness of metal transfer, the depth of fusion and the amount of spatter, especially when welding thin sheet metal or in forced positions.

Additional features often found in this class of Telwin equipment, such as adjustable wire-burn time (Burn-Back), prevent the wire from sticking to the current tip after welding. The feeder ‘s soft-start function (Soft Start) ensures a smooth start to the process, minimizing spatter at the beginning of the weld. Selectable 2T/4T and spot welding modes further expand the machine’s range of applications. These advanced control options give the welder complete authority over the process, allowing the machine to be tailored to the specific requirements of each job and material, which is the key to achieving welds of the highest radiographic quality.
